Hello, I'm new here. I found your site when searching for information on getting my Sensi-Temp burner to work, and getting my range in better condition.

This range came with my house, and I have loved it from the first time I used it. How can anyone do without a double oven? It is simply fantastic. I'm not sure what year it is, but I would guess late 60s.

What I don't like is that the burners are dodgy. Most of the time I can get the three main burners to work, and for a brief period of 3 or 4 months, the sensi-temp burner started working. But now when I turn it on, there's a hum and the knob vibrates very slightly. It does not get hot.

My Grandpa is a retired appliance repairman, but as he's in his late 80s and 250 miles away, he's no good for an on-site visit. All he told me was "Those sensitemp burners go bad all the time--replace it with a regular burner". My local appliance repair company said there's no way to replace it with a regular burner and they can't get parts to fix it.

I have seen enough posts about these to know that what Grandpa said is true--they do go bad. But I've also seen quite a few that appear to be very promising with the possibility of getting it working again.

I don't have much experience with electrical work, but my husband does have some experience. What would you recommend for the next steps? Any good resources on how to go about this?

Also, the plastic covering the front of the clock is stained with grease on the inside (ugh!). Any tips on how to disassemble and clean? I'm at least happy the clock and timer work, as does my light! If I can get four functional burners I will be a happy camper.

There Is Hope!

danemodsandy's profile picture
The problem with your Sensi-Temp burner is almost certainly the sensor (the part in the center of the burner), or the responder (behind the knob). Given that you're hearing a hum and feeling the knob vibrate, my money would be on the responder. To put things in terms that are perhaps overly simple, the sensor determines the temperature of the pan, and the responder adjusts the temperature to give you what you set. The sensor's job is to tell the responder what is needed.

One member here, John, whose handle is combo52, sometimes has parts for these units. He's going to need to know your range's model number and serial number; both these numbers will be on a metal plate on the frame of the oven door opening. John can also help you diagnose the problem better. Parts also turn up on eBay.

John can probably help you diagnose and repair the problems with your other burners as well. I can see one problem on your right rear burner (the 8-inch unit without Sensi-Temp); the burner looks as if it could have been badly overheated. This often occurs when someone has been cooking on high heat, takes the pot or pan off the burner, and then forgets to turn the burner off.

Your range is a top-of-the-line 40-inch range from about 1972. It originally had a griddle, a rotisserie and a meat probe thermometer. If yours still has all those accessories, you have some real rarities.

The range is very much worth keeping and repairing. You will not find anything on today's market that even begins to approach the quality level of that unit.

Thank you!

Thanks for your help. I will find out the model and serial number and update the thread. Also, I do have the meat thermometer, but not the griddle or rotisserie. I will have to keep an eye out for those accessories second-hand!

As for the rear right burner, I'm amazed you could spot anything wrong in that cell phone photo. I'm sure you are right--As I look at it carefully, the burner does appear to be damaged. I hadn't paid too much attention to it because it does work, but now I can see it should be replaced. Who knows how long it has been that way. I can't think of any time I have overheated it by accident, but this stove has been around longer than I have.

It'll All Be Okay....

danemodsandy's profile picture
Once you have a model and serial number, John can advise you of parts availability and cost. Be aware that Sensi-Temp parts are not cheap, but I have always found John's pricing to be very fair.

John runs a busy appliance repair service in the D.C. area, so it can be a few days before he has time to log on here, scan the threads, and find ones that he needs to look at. Please don't despair; John is a businesslike person and will get to it.

Also, as you look at repair costs on your range, it will be useful to go to your local Home Depot or Lowe's and look at their ranges. Look at the cheapest ones you can find, and you'll be shocked at what these stores are asking for pieces of garbage. When you are totaling up repair costs for your range, they will not be as much as that, and you'll have something worth owning when you're done.

P.S.:

danemodsandy's profile picture
Looking a little more closely at the photo you provided, your range is later than 1972.

In the mid-1970s, the Feds regulated a feature that had been on ranges for a long time - convenience outlets. Those were electric outlets on the backguards of ranges; ranges with automatic ovens like yours usually had two - one regular outlet, and one timed outlet controlled by the automatic oven timer. You could use the timed outlet to start percolators, etc. automatically in the morning.

However, your range does not have these outlets, so that makes it mid-'70s or later, after this feature was regulated out of existence. The Feds felt that stupid people might melt an appliance cord on a hot burner, so they made sure no one could have convenience outlets.

Here's a photo of a slightly earlier range that does have the convenience outlets, at the very bottom of the backguard, under the burner control knobs. The photo is cut off, so only one is in the picture, but there were two on this model:

Model and Serial #

The Model Number is J CP 6800 1 WH
Serial Number: DZ 224927 G

Based on a chart for serial number/manufacture dates, it looks like this puts it at February 1976.

John combo52 will hopefully be along presently. I've also sent him a private message to let him know you're in need of assistance, linking him to this thread.

P.S.: Glad to see you found the GE date decoder and used it by yourself. If you're going to keep vintage appliances running, that kind of initiative really helps.

Sensi-Temp

robinsondm's profile picture

Carrie,

 

I have a 1966 40-inch GE Range, and the Sensi-Temp feature is definitely worth having. I repaired my Sensi-Temp in 2000, and it has continued to work since then. My range needed both a sensor and a responder, and back in 2000, GE still sold both parts (not any more, unfortunately).

 

According to repairclinic.com, which is usually pretty accurate, your Sensi-Temp sensor is part number WB21X5207. That's the same as on my range. Repairclinic doesn't report your responder part number, but IF it's the same as on my range, that would be WB21X153. That part is available on eBay now. As Sandy mentioned, John (combo52) may also have the parts you need.

 

Another tip: If you want to confirm the above part numbers, you can call GE Appliance Parts at 1-877-959-8688. For an older range like yours, they may need to look up the part numbers on microfiche, which takes several minutes -- and you may even need to call twice before getting all the information you need -- but this is a helpful service.

 

Good luck with the repairs, to a fellow owner of a vintage GE range!

 

Dean

SenceAtemp burner issues

combo52's profile picture
Hi Carrie, the most likely failure is the sensor, you can check it by testing the resistance across it, if it is OK you should come up with about 17.5 ohms, if it tests bad and you want to check weather the responder is good just connect the two yellow wires together and the burner will heat at FULL HEAT, it is not a good idea to leave the sensor bypassed [ you will end setting fire to something ]. I do have some good used sensors that I will sell if you find this is all you need and want to try fixing this neat feature, if it were me I would fix it.

It is also fairly easy to install a regular infinite switch on this range and if you do you do not lose the three size burner or the grill feature.

Deans advice is good, your range uses the same sensor that his needed, the responder however would have a different part#.

For the record the Feds had nothing to do with convenience outlets disappearing from ranges. This was done by UL Underwriters Laboratory, which is a private [ non government association ] that is supported by the appliance industry [ and others ].

This was a good regulation and an easy one to get range manufacturers to agree to BECAUSE it saved them MONEY and because everyone dropped the feature at the same time there was no sales disadvantage in eliminating convenience outlets, at the same the push to turn safety controls also became mandatory [ another life saving feature that your range has, both of these features became a UL regulation in 1974.

John:

danemodsandy's profile picture
I gladly stand corrected on the source of the mandate against convenience outlets, but I will forever wish that it had not happened.

On my present GE J 370 with convenience outlets, I have the happy option of starting my Farberware perc automatically in the morning, without the use of a cluttering plug-in timer. The non-timed outlet also gives me an additional outlet on that side of the kitchen, and outlets are manna from Heaven in houses built when mine was, which was 1950.

I'm glad to hear you think Carrie's problem is the sensor. That's easier to get to and to replace than the responder, at least for us non-pro types. I'm sure either assembly would be a piece of cake for you.

Convenience Outlets On Electric Ranges

combo52's profile picture
Hi Sandy And Hans, yes I agree with both of you, convenience outlets on electric ranges could be very useful in older homes that did not have enough circuits in the kitchen, many a portable dishwasher was run on these outlets along with waffle irons, clothes washers and on and on. The convenience outlets were less useful on gas ranges because they were usually just plugged into the general kitchens wiring, but on an electric range you got a separate dedicated 15 or 20 Amp outlet.

Post# 743380 , Reply# 12   3/19/2014 at 21:05 (1,362 days old) by norgeway (mocksville n c )        
I use them for..

The waffle iron/electric frying pan or the electric deep fryer, also the crock pot,they are also great when making 7 minute icing,'portable mixer"..The push to turn knobs spelled the end for pushbuttons, which I always loved.

Carrie (zinniz),

 

There's a Sensi-Temp sensor on eBay now, for what I think is a good price. Of course, John (combo52) may be able to sell you one at an even better price. I'll leave that up to you and him.

Woo hoo! I just got that part on eBay. Even if that's not what's wrong right now, it will be great to have it for future needs.

John--I will test the sensor after work today. I really appreciate your advice!

Probably is the sensor...

I got out my husband's multimeter and I'm seeing 4.7 ohms across the sensor. I also pulled the assembly out and from the looks of it, I would say someone has attempted a repair in the past. I haven't seen a photo of one of these things from the bottom so I can't be sure but it certainly doesn't seem like this is how it should look.

Gray stuff on sensor

robinsondm's profile picture
Carrie,

Great job nabbing that eBay sensor! You're welcome. ;-)

If you're talking about that gray blob on the bottom, when you say the sensor doesn't look normal -- actually, that is normal! I've replaced my Sensi-Temp sensor in the past, and they do have that gray blob of stuff -- I assume it's a high temperature adhesive and/or sealant -- on the bottom.

I just wanted to mention this, so you won't assume something is wrong with your new sensor. Good luck,

Dean

Thanks again for the info!

Dean,

Thanks for letting me know that's normal! I would have figured it out when the new one arrives, but it's good to know the previous owners weren't hacking around with it this time.

Since I started looking into all this, I've replaced the damaged burner in back, and while I was at it got some new drip pans and rings. My stove is looking better than ever and hopefully soon will be running with 4 burners again.

Carrie.

I also have a question. about the sensitemp.

Hi guys,

I'm new to the forum. I just found it. I have been trying to find more info on my 40" GE P7. Mine has the knobs and no buttons. I think it is from the early 70s. It is Avocado colored and my wife hates it and wants to get rid of it. I love it and want to repair the little things that are wrong and get another 40 + years out of it. I have used the sensitemp burner because the other 8" burner stopped working. I just got a replacement 8" burner to fix that. The sensitemp burner works well still, but sometimes it gets to temperature and cuts off, but doesn't come back on. could that be an issue with the sensor or the type of cookware? Also, I plan on replacing the 8" burner and cleaning the area under the top, but I am having trouble getting the top off. Is there a latch or magic button?

Drew

SenceAtemp burner issues

combo52's profile picture
Hi Drew, it is important that the cookware be flat and most importantly the center of the pan must be in good contact with the sensor for proper operation.

Keep in mind when cooking on these Calrod style surface elements, and you are using high heat, THE ELEMENT SHOULD NEVER GLOW RED HOT, if it does you need better cookware, this is true of any electric range with conventional elements.

Drew it is fairly difficult to remove the cook-top on your range, it is usually best to just clean through the burner openings.

GE Recommended

Medium weight aluminum cookware for best operation of the Sensi Temp, they stated in the owners manual to use a lower than normal temperature for other materials..ie, stainless or iron.Some people are afraid of aluminum these days, but it really does respond quickest to heat changes.

It worked!!!

My new sensor arrived in the mail today! It only took a few minutes to install and I have a working burner!! I tested it on a medium boil and I can not wait to "Get to know" my sensitemp better. I am kicking myself for listening to the repair guy who said nothing could be done.

You guys are amazing! I am ever so thankful.

Here's my new sensor in action, burning off years of gunk as it heats up some water.

You GO, Carrie!

danemodsandy's profile picture
I am so glad to hear - and see - that your range is looking and working great, ready for a few more decades of culinary adventures.

In case you do not have it, the GE Sensi-Temp instruction manual is a must, because Sensi-Temp doesn't work exactly like many people think it does. A lot of people try to use it strictly with the temperature settings, when in fact you need to use the "Boil" settings when cooking with liquids. And it never needs to be cranked up red-hot, as John combo52 mentions above.

Again, the Sensi-Temp guide can be downloaded from Automatic Ephemera for only $1.99. Robert, the owner of this site, runs AE as well. A link directly to the page for the Sensi-Temp guide is below.

Again, congratulations on your first vintage appliance "save," and I am willing to bet there are more in your future! Glad we could help.

Glad you like the Sensi-Temp guide! The cookware drawings in the book are of a Wear-Ever line of cookware called Hallite, which turns up a lot in thrift stores and on eBay. I keep meaning to nab a couple of pieces and see if it's any better on the Sensi-Temp than my aluminum-clad Farberware.

Not that anyone's going to pry me away from my Farberware, you understand....

Hi

sarahperdue's profile picture
Hi Carrie,

I'm Sarah. I love seeing your range and have enjoyed this discussion about the Sensi-Temp burner. I have a Hotpoint with Hotpoint's version of the Sensi-Temp and hope to take on fixing it sometime in the not so distant future. I love your analog clocks. Mine has the mechanical digital clock, but it was a major upgrade from the 30" Kenmore with the rusted through oven liner, so I bought it especially since the large oven is self cleaning.

Glad you found AW. I agree with Sandy, once you successfully repair an old appliance, it is hard to resist taking on another.

Sarah

Speaking of Hotpoint...

Hi Sarah,

Good luck with fixing your Hotpoint! It's funny that you mention you have the Hotpoint version. When I was working on my stove, I noticed that the part box had both brands listed on it, and I had wondered if they existed on Hotpoint ranges too.

Carrie.

Just got mine working....

I love, love, love it! I have a gorgeous 1969 model. I had to run new electric service for it, as I had hookups for a propane oven. So I just got all that done, and after reading here, realized my sensi temp sensor is also not working. Everything else does. I have the original griddle and it is in almost perfect condition. I don't have the probe, sad face, but this range is immaculate, inside and out. Even the back is clean, without built up grease, etc. I feel VERY lucky to have come across it.

Some things I need are the drip pans, sensor and probe. If anyone has these, I would be eternally grateful! If no sensor is available, I would love to know how I can make that burner function without one. Someone tried replacing the pans, but the coils don't fit on top of them, since they aren't notched. I haven't been able to find the correct item replacement for them. I am so glad I found this forum and thread!

Any help is greatly appreciated!

Welcome to AW.org.

John combo52 is the GE expert around here, so I'll let him advise you on the repairs. Your range is well worth saving. It's from around 1972, as can be seen from the rotary controls and the convenience outlets on the control panel.

Nice range!

I also have a 40" GE range with a sensitemp burner that is not working. GE no longer seems to sell the parts but I understand one of the members here may have parts available? I would be interested in pricing. The range is a 1978 model (jcp68ow1wh)

It does not seem to matter what position the power saver switch is in, there is a slight amount of heat from the burner if you turn on the switch, but never gets hot. I hear a low hum when the burner is on, but no vibration.

sensi temp repair

I also have the situation where the sense temp burner starts to get warm for a few seconds, then shuts off. I also hear a slight buzzing or humming noise coming from the responder unit (that's the temp setting control on the dash of the stove). Mine is the older ten ohm sensor model. The sensor is located in the middle of the burner. I actually don't think anything is wrong with that, but there is also a relay inside the responder unit which I believe could be causing the problem. Newer units were, I believe, upgraded to a 17 ohm sensor along with other changes. A replacement responder unit might still be available. Mine is not, it's from a 1961 stove, but there is surely somebody here who can help you with your stove. The only information I could ever find was from a G.E technical talk manual, which said something to the effect that when they checked the parts that were removed, the sensor turned out to be fine, and that it was the responder that needed to be replaced. Other members here have stated that they believe it's usually the sensor that's the cause of the problem. There is a check out sequence to troubleshooting these units, but I don't have it available to post right now. Hopefully, somebody with more electrical experience than me will give you some information and assist you. Good luck. Les

Sensi Temp

Was a great feature.....WHEN it worked, unfortunately I have never seen one that did work, as many old stoves as I have had down thru the years, only the ones that were on gas ranges worked, and they were great.

Sensi-Temp

I am glad to have found this forum.

We have a GE sensi-temp range in excellent condition and everything works except the sensi-temp burner. We used it to bottle grape juice this last week-end.

Our unit appears to have been manufactured in January 1970 - or January 1954 based on model and serial numbers and using the GE Date Decoder. I am guessing earlier than 1970 because pictures above for a 1969 model show dial controls. Our unit has pushbutton controls for all of the burners but with a dial temperature control for the sensi-temp burner. (I graduated from high school in 1969 and I am pretty sure I remember having the unit for some years before that.)

Could this unit really have been made in 1954?

Model # J485A1WH
Serial # AL00079

Unfortunately I am not able to provide a picture at this time because the unit is in another location.

Visually it appears that the sensor unit is damaged. Are replacement sensors still available through John? Nothing appears to be available on eBay now.

This thread seems to have gone "cold" with the most recent entry before mine almost exactly one year ago.

I would appreciate any help that could be provided to fix the sensi-temp burner on this awesome range.

Seni-Temp

I have a vintage GE stove, circa 1963, and I also am looking for a sensor.

Model #J 346 14711.

Anyone have one or could you point me to one?

Thanks in advance.

First automatic GE burner was the hydraulic controlled "Automatic Calrod". Around 1960, I believe, it was changed to an electric control and renamed "Sensi-temp". The first Sensi-temp used a different sensor than later Sensi-temp. I don't know what year that change was made. The part number for the second style is WB21X5207 and has yellow leads. Im sure someone here knows year of change and part number for the earlier sensor.

Best bet is to look on ebay. I got one there earlier this year. They are usually quite expensive but keep watching and eventually one will be listed at a "reasonable" price. You can follow a search and ebay will email you an alert when one is listed.

Look at this old thread for a picture of one version of electric sensor. Its referred to as being the earlier one. Looks like it had white leads.

sensor or responder unit?

is that the sensi temp sensor unit (in the middle of the burner), or the responder unit (which is in the console)? Maybe posting a pic of the stove would give an idea of the year? I can remember reading somewhere at this site, some communication between the techs in the field who were repairing them, then sending in the parts for testing, and the company finding out that the sensor unit in the middle of the burner was rarely the problem. It was usually the responder unit, in the console. I did see a responder unit on eBay recently, for 89$. Don't know what year it is for though. On eBay search you can type in 'vintage General Electric' and see what comes up. Good luck to you. Les

Non Heating Sensatemp Burners

combo52's profile picture

70-80% of the time the sensor is bad, Part # WB21X5207 is the sensor that was used on all GE STBs after around 1962-the mid 80s when GE discontinued this wonderful feature.

 

The other 20-30% of the time you either have a bad transformer or responder. In rare cases you may have a broken wire where the wires connect to the element and even more rarely you could have a bad element. The elements seldom failed on STBs because the sensor system protected the element from the overheating abuse that many users of electric ranges put the surface elements through by running them red hot with warped or too small a pan on larger elements.

non-heating sensitemp burner

John (combo52),

my husband isolated sensitemp sensor, checked continuity and there was none.

do you know where we can get one of these or do you have one for sale? i have checked ebay and online with no luck.

thank you and take care.

Hi Sirena, thanks for asking but unfortunately we have exhausted our supply of these sensors at this time. They were used for a long time so if you keep checking on line you may find a good new or used one. Two weeks ago I was working on one of our customers ranges that had a bad sensor and I converted to a regular infinite switch.

thank you john - combo 52. i am so sad...this stove has been in the family for 50 yrs! is it expensive to convert to a regular burner?

Combo 52,

What are you referring to when you said you converted a unit to a regular infinite switch? My sensor is out on my stove. The last time I replaced it GE still had the part available. They show up on eBay but are pricey.

You can install a regular infinite switch in place of the responder control and the burner will work like a newer range.

 

GE had a kit to do this on any ST burner range they ever made, I dough that the kit is still available but any good tech can install a regular inf Sw kit in about 30 minutes so you will still have full use of the burner.

Looking to sell my GE P7 40" range

Hello - I am remodeling my kitchen and am looking to sell my vintage GE P7 40" range. The model/serial number tag is only partly legible. All I can see is J CP 68. Looking at the first post above, my range looks identical. Can I assume that it is also from 1976? The kitchen was last remodeled in 1952, but based on what I find online, it doesn't look like an early 1950's model. Also, any idea on how to reach people who would be interested in it? The main oven works well, including the self-clean feature. All burners work, but the Sensi-temp burner is wobbly. There are two heating elements in the smaller oven, the top one works but the bottom one does not. Thank you for any info you can provide!

That's a beautiful stove.

The thermostatically controlled burners prior to induction were all (at least in my experience and that of everyone I know, whether in the US or Europe) next door to useless. At best.

I'd not worry about it. The bottom heating element is not going to be too hard to find.

I'm too far away, but, gosh - it sure is pretty.

This link will take you to GE's site showing the chart to date your range. The first two letters in the Serial number designates the month and year of manufacture.

GE Sensi-Temp Burner

combo52's profile picture

Was one of the best features of these great ranges, the only time we found customers that did not like this feature was when people had no mechanical sense and never read how to use it.

 

You could not only cook almost anything with just one initial setting of the dial including baking a cake or even baking things like potatoes in a regular sauce pan with out a lid or water in the pan.

 

Your element that is not sitting level is easy to fix, it looks like the drip pan is sitting on the trim ring [ it is supposed to sit in the opening of the white cook-top and then the chrome ring sits above ] Also if the burner does not drop all the way to a level position the pivot stop needs a drop of oil.

John,

panthera's profile picture

I don't question that the sensi-temp under ideal conditions worked well. At least when the entire system was running.

Just - the restrictions were considerable as to material, size, etc.

I'm old enough to have used many variations on the system, here and in Europe and, well - let's be fair here - given that it's not the least bit unusual for a regular burner/control to run without adjustment or repair for over 50 years, how long does one get from a temperature controlled unit before there's this, that or the other major problem? Two years? Five? It sure as heck isn't long, not compared to how the indirect controls last.

GE Sensi-Temp Burners

combo52's profile picture

Do not have to be used under ideal conditions, I use glass and cast-iron cook ware on mine, and they are actually more durable than non heat controlled elements, in fact I have NEVER seen a bad element on a GE ST element, because it is hard to abuse a heat controlled element the elements are not stressed and never burn out and warp.

 

The hydraulic controlled elements that were used on European and many US electric and GAS ranges alike almost never failed in the life of a range, I have no idea of where this 3-5 year life crap comes from Keven but they haven't even built many of the controlled elements we are talking about since the 70s and into the 80s and I never saw any that only lasted 3-5 years, I don't know where you come up with this crap.

Sensi temp trouble

I recently replaced the sensor but the burner will not work. I disconnected the sensor and connected the leads and it works on high temp without sensor... all the buttons work..did I get a bad sensor?

Post# 971325 , Reply# 59   12/3/2017 at 17:27 by speedqueen (Harrison Twp, Michigan)        

I believe there was a mention of using an ohm meter across the sensor and that it should read about 17.5 ohms. With that info, I am sure John(combo52), our resident expert, could help.

OK...I've noticed he is the person to talk to..I've gotten more information from this site than any other. To add to the my confusion is the wiring diagram...that's where I had to stop...it's helpful but wires from the sensor to the responder don't look right

Thanks for the reply. The sensi-temp ("automatic calrod" on mine) has never worked since we got our 1958 GE. I was wondering if 5207 would work or not.

The sensor as mentioned should be around 17.5 ohms at room temp, if you want to check the entire sensor circuit check for 17.5 ohms at te responder control with one of the yellow sensor wires disconnected from the responder [ and the range unplugged of course ]

Post# 971466 , Reply# 67   12/4/2017 at 11:10 by Coop58 (Texas)        

Thanks John..does the sensor connect directly to the responder? Also do the T S T S connections on the responder mean T for transformer and S for sensor?


Post# 971477 , Reply# 68   12/4/2017 at 11:55 by Coop58 (Texas)        

Hey spacepig I would suggest buying parts based on the model number or if you know the part number.I purchased my based on it looked the same it was a a perfect fit but that doesn't mean it will work. I have yet to find my model number even exists

I do have the GE parts manual downloaded from the ephemera, and I usually check it against part numbers of the e-bay sensors. So far, no match on the part numbers.
I would even be ok with losing the sensi-temp and putting a regular burner/coil there, but that looks a lot more complex than it sounds (at least to us since we don't know what we're doing).


Post# 971571 , Reply# 70   12/4/2017 at 20:37 by Coop58 (Texas)        

I know I wouldn't attempt changing over to an infinite switch either...what was the sensor number you are looking for?

There are lots of the 3 size 8" burners available, I have good used and new ones alike that I will sell. I do not have any sensors left for them however.

 

New ones may still be available from GE, We sell good used ones for 1/2 of the new price.

Sensi temp trouble

When I disconnect the sensor and then connect the leads and the burner works does that mean the responder and transformer are good?
