We were visiting some friends of ours and his wife asked us if I work on ovens. I said maybe and asked what's wrong with their gas wall oven. This is what I was told.

"When I use our wall oven I turn it up to about 250F and then walk away. About 5 minutes later I hear a "pop" sound and both the oven door and the broiler door come flying open all on their own. Then the oven is heating up and I can increase the temp to whatever I wish with no further problems. What could be wrong?"

I looked at the oven and my friend says this is a 1980's model oven but when I look inside I don't think the thing has ever been cleaned. The broiler area was what I considered to be unusable because of all the dirt & grime. It's not a self cleaning model. Just a single gas wall oven with broiler.

It's a Caloric Model: RXP-212 S/N:5285719. I told her to stop using it because waiting until the thing backfires and blows the doors of the oven open is just not safe. Could it be that the ignitor has been contaminated by all the dirt in the oven and is not working correctly? What do you all think?

Sounds plausible..

An aunt of my ex had an older gas stove, (I can't remember the brand), with a pilot light rather than if igniter, which would do that, of course the oven didnt blow fully open, the door would bounce a few inches open and slam shut, thanks to the springs .

I finally convinced her to get it looked at, and it was a simple matter of the pilot light being adjusted. After that it was fine.

A classic case of delayed ignition. Igniters get weak and have to be replaced, although I was under the impression that a certain temperature had to be measured in a link between the igniter and the gas valve before the gas valve would open. I would not work on any gas appliance unless I had lots of liability insurance. It is a job best left to professionals so that if there is some unfortunate after effect, there would at least be training/certification to show that they were not entirely responsible for any destruction.

My mother....

had a BRAND NEW Magic ---- stove and the oven was making a booming noise also. The repair man told her she was lucky the thing didn't blow up as the entire oven filled with gas until the ignitor came on.

I wonder if you could hold the doors closed and force flame out of the oven vent. That would make a good video in the style of the guys who blow up microwave ovens.

I'll pass that on to the people who own the oven. Taking the oven out of the wall to run the wire from the igniter to the gas valve would be a bitch to do. I am sure that these ovens are not lightweight.

I'll bet anything that any repair guy they call will tell them just to buy a new oven. That seems to be the way things go these days.

If it's that dirty, it's possible that only one side of the burner is lighting. The raw gas would escape from the other side, until the flame lights it. Try a good cleaning of the burner.

Exploding Coloric Gas Wall Oven

combo52's profile picture

This was a very common problem with Coloric Gas wall ovens and free standing ranges with the Ultra-Ray broiler burner in the 1980s and to some extent with ALL GAS OVENS, with flat hot surface igniters.  Allen does this oven have the UR burner? or a regular looking burner tube with holes punched down both sides.

 

 

The most common reason for this occurring is an old weak igniter, but as I mentioned Coloric had problems with the gas getting to the hot ignitor on the UR burners so additional adjustments needed to be made to make these ovens work properly.

I wonder why she starts it at 250 and then turns the thermostat higher after the doors blow open.

Exploding Coloric Gas Wall Oven

I am sure it does not make any difference what the thermostat is set for when turned on for the first time and often once everything is heated the delayed ignition does not happen again. I guess it just makes the user feel better if she works the temperature gradually, LOL.

I asked her about that and she said that's the way she always has used it. What does the UltraRay burner look like? Is it kind of a flat burner with holes around the parimeter edges near the top?

It has a square igniter that looks like it's mounted with two screws on the right hand side of the burner.

The Caloric Ultraray burners I have seen have a surface that looks like stainless steel screen.

I asked about the 250 setting because all of the instructions I have seen for gas and electric ovens simply say to turn the thermostat to the desired setting. Some older gas ranges tell you to strike the match before turning the thermostat knob.

It might be interesting to watch the burner from when the oven is switched on to see what happens.


Post# 684019 , Reply# 14   6/15/2013 at 19:23 (3,975 days old) by whirlcool (Just North Of Houston, Texas)        

Nope, no screen like things in there.

I'm reminded of my sister from years ago. Our parent at one time had a manually lit gas oven. You light the match, turn the gas on and drop the match down a hole on the floor of the oven at the front of the oven where it said "MATCH>"

One day my sister turned the oven on and realized that she didn't have any matches nearby, so she went searched the house until she found some. She then went back to the oven and lit the match so she could light the oven. As soon as she lit the match she said the oven came up off the floor about a foot and it made a big boom! noise. Her eyebrows were singed off of her face and some of her hair was singed. I remember laughing my you know what off at her. But it could have been a very dangerous situation. She was about 12 at the time.

So you have to be careful around those things.

Granny's previous gas range had a weak igniter (glow bar) for some long while until it quit completely.  Took several minutes for the oven to light, and usually there was a mild fooom when it did.  Substitute replacement part was available but more expen$ive than rea$onable so the oven was unused for a couple years until we replaced the range.

Singed Hair

rp2813's profile picture

A common occurrence next door when I was a kid.  The mom there, Coral, couldn't hold her alcohol.  One drink and she'd be flying.  Harry, the patriarch, was Irish so it's no surprise that the household revolved around alcohol (the atmosphere there was always festive) so Coral was flying most evenings.  Thankfully, she never drove a car, but a lot of her luncheoning and card partying friends did.  At least those events ended well before commute time.

 

Coral was always the life of any party.  My dad would say, when Coral walked in, she lit up the room.  She also had an affinity for lighting up her cigarettes via gas burner on the stove.  Every once in a while my mom would share what didn't take long to become old rehashed news over the years:  "Coral singed her hair again last night."

 

It's probably been 20 years since Coral left for the big party in the sky, but I still miss her.  It was a big loss to the old guard in the 'hood here.   As my sister put it, growing up in that family was like having Holly Golightly for a mom.

I sent a video over to my friend who owns this oven. It explains how the ignition system works. So he pulled the floor of the oven and looked around the burner and the ignitor and found nothing. So he reassembled it all and tried it again and within 15 seconds after turning the oven on the burner ignited. No more explosive doors.

He tried this 10 more times over a 24 hour period. It worked each and every time.
He thinks that maybe there could have been a weak connection. If it does it again he's going to replace the oven.

But he said thanks to all of you who helped me out with this!

I'll bet that in reassembling the parts, he positioned something slightly differently so that the gas flows more toward the igniter than it did previously. Modern gas ovens, for the most part, use a sheet of steel over the burner instead of the cast iron like old gas stoves used and that thin steel warps which causes several problems.

Well the oven has been working well again for the past few weeks. Now it is doing something new. It'll ignite the burner pretty quick. But after running about 15 minutes it turns itself off, it'll maintain 350F and then when the temp drops below that it won't relight. If they turn the oven to off wait 10 minutes it'll relight but after about 15 minutes it turns itself off again.

To me it sounds like a thermostat. I have read up on gas safety valves and it seems that they just fail, i.e. not go intermittent.

Personally, I think this oven just wants to be replaced.

NON RELIGHTING COLORIC GAS WALL OVEN

combo52's profile picture

Could be a thermostat, but I would need more information. Instead of turning the oven off when it will not come back on why not trying turning the thermostat to a hotter setting, even 500F. If it comes back on then it is likely a bad thermostat, if it still does not come back on for 15 minutes it is more likely a bad gas valve, pressure regulator etc.

There is a photo of one at the beginning of this thread.

We tried to bump up the temp from 350F to 450F after it fails. Nothing, still no relight. The only way to get it to relight is to turn it off for 10 min and then turn it back on again.

The gas valve for this model is NLA. The thermostat is still available.

This is the first gas wall oven I have seen. Most of them are electric.

OK, so my friends decided to replace the Caloric wall oven. They now have a new problem. The space it is located in is only 22 inches wide by 38 inches high. The cabinets will not allow for any modification of the opening.

The only oven they have found is a Summit brand oven. I've never heard of these. It looks like Summit is a specialty manufacturer in New York.

Any suggestions?

Send your friends online to AJ Madison. Maytag, Frigidaire and GE all still make a gas oven that will fit the space. Summit is poor quality. Greg

We see GE 24 inch ovens, but will they fit in a 22 inch wide hole?

I recommended that to the guy who owns the Caloric. He said that there is only a 117V outlet back there and a gas line. He doesn't want to have to run a 240V line into the cabinet. Isn't there a way to get 240V in there by swapping the wires at the box and the outlet itself?

I do see that some 24" ovens only require a 22" mounting hole.

Unless money is a serious issue, I would heartily recommend that your friends bite the bullet and do whatever's needed to get 220 in there.

Electric ovens are usually much, much better bakers than gas ones, and having self-cleaning is an amazing advantage if you've never had an oven with it.

Your friends will be happy with their new oven long after they've gotten over the expense, trust me.

My two cents------

Contemporary gas ovens have electrically controlled valves, so you (one) is/are SOL for baking/roasting/ broiling in a power failure. That said, any gas cooktop burner I know, can be lit with a match or a butane candle lighter.


I reluctantly agree about converting to an electric wall oven, mostly because of the greater choice. Allen, I urge you to urge your friends to keep their gas cooktop, especially in the case of prolonged power outages, after hurricanes and other disasters.


As for the baking/roasting ability? I have used both, quite successfully.


I repeat from: The Fannie Farmer Baking Book, by Marion Cunningham: "I've found no important differences between gas and electricity in baking- either can produce fine results as long as the oven is performing well."

Emphasis added by me.



Again, this is only my experience/opinion, those who have had poor results with gas baking either have had poor or poorly maintained ovens (rental much?) or perhaps don't know their elbows from a can of Crisco.


Incidentally, I have had lovely results from my 2011 gas Whirlpool, and better than adequate oven cleaning.

The 120 wiring that is in place won't supply the current necessary to operate an electric oven.  While technically it could be wired to supply 220, the current rating on a 14-2 wire is not such that you could power up the wall oven.  If the owner can't rewire then you are looking at gas. 

 

Regarding the 22" width, most wall ovens will overlap the sides a bit, if the dimensions of the opening match he should be OK.


Post# 687389 , Reply# 32   7/4/2013 at 23:54 (3,956 days old) by hydralique (Los Angeles)        

Remember that the advertised width of a wall oven is nominal, not actual, so you have to check installation guides to see what size hole is required. I'd be very surprised if that old Caloric is anything other than a standard 24" size. Actual appliance sizes do vary slightly by manufacturer but it's not much, and most likely the hole can be enlarged a tad if needed, though there is no way to tell how much enlargement can be done without removing the oven and looking at cabinet construction. The market for 24" wall ovens has been ossified for years and years as this is an old size that nobody uses in new construction today, but there are millions of old ones across the nation; it is not in the best interest of any manufacturer to make a 24" oven that won't fit old cabinets.

 

If this replacement were a part of a kitchen remodel with new cabinets it would be foolish to not convert to a 27" or 30" electric oven as there is a much better selection, but I can't imagine justifying the expense of electric conversion to keep a 24" oven when several manufacturers still make gas models that work just fine. Running wire for an electric conversion is just the tip of the iceberg, more than likely there will be drywall patching, paint matching and lots of other PITA considerations. You cannot convert a 120 v outlet to a 240 v outlet because the former needs only a hot, a neutral and a ground, while the latter requires all these plus an additional hot.

Money is not an issue with these friends of ours. Just the willingness to spend any is.

Their house is a typical mid century house and the wall the oven is in is a wood cabinet that sticks out slightly from the middle of the counter top. Plus it has electrical switches on one side of it. So any widening would be difficult at best.


I am afraid that once they see the price of new ovens they'll go back to trying to fix the Caloric again. They did say that tomorrow they are going to visit the independent dealer from whom they purchased the Caloric back in the mid 80's and see what they can do for him.

To tell you the truth if they buy a new oven, I think it would be best for the dealer to install it. The job is a little more than I wanted to handle.


Post# 687436 , Reply# 34   7/5/2013 at 10:03 (3,956 days old) by hydralique (Los Angeles)        

You have to make a distinction between widening the cabinet and enlarging the hole already in that cabinet. The front bezel of the oven is approximately 24" wide and covers the the hole behind it, while the cabinet itself must be wider than the bezel, thus there is always some room there. Usually if any hole widening is needed it is on the order of a quarter-inch or so and can be done with a jigsaw. The switches could complicate things, but shallow switchboxes are available. Basically, the old oven will have to come out to determine how much room there is for a new oven and what needs to be done to install it.


Post# 687499 , Reply# 35   7/5/2013 at 17:40 (3,956 days old) by whirlcool (Just North Of Houston, Texas)        

I was talking to this friend today and told him it may just be better to run a 240V line to the area where it will be needed for a new oven. He very firmly told me that he will not run an electrical line in there because it's an old house (1956) and there is no sense putting money into it. He said his wife doesn't use the oven enough to justify buying a new one.

OTOH, his wife is bitching pretty much about not having a oven that turns on and operates correctly each and every time it's used.

To even make matters more confusing they live in this house in Houston 3.5 days out of each week and live in their other house (a restored victorian) on Galveston Island the rest of the week.

So the equation here is how long will his wife have to bitch at him before he buys a new oven?

I told him that it's his decision to make and that's the end of my involvement in this mess.

This friend does have some money spending issues. A few years ago he accidentally sat on his cell phone breaking the LCD screen. He continued to use it for three more years afterwards.

Once we were in a restaurant and when he flipped the phone open a few little bits of the screen fell on the table. I mentioned that he may consider buying a new phone.
His response "Hell, it rings when someone calls and I can make calls from it. Why would I need to buy a new phone?"

It always amazes me how often people with real money will get very tight over repairing their expensive toys.

You got that right! Sometimes they don't even bother with a repair and just use the broken toy until they can't squeeze any of the last little bit out of it.

And sometimes they just get bored with stuff - must be nice to have so much you don't have to maintain any interest in it after you've had the thrill of buying it.

My personal favorite is my Singer Touch-Tronic 2010 sewing machine in the solid oak TOL No. 166 Flip 'n Sew cabinet. New? $1000 for the machine, $400 for the cabinet. Used? $130 for everything. She "just didn't care about it any more."

Well, I recommended the conversion to electric oven to this guy and he said he can't justify the cost based on how little his wife uses it. So he knows what his options are and now it depends on how long he can stand his wife bitching at him about this.
It may be years......

Like I said, money is not an issue for these people but the willingness to spend it is. Now it's up to them to take care of this.

Wow, so cool to finally find something online about my very problem! My Caloric lp wall oven did the EXACT same thing, doors would blow out when ignitor finally caught. Doors are on nice strong springs, though, and they would spring shut again. Eventually, I would just leave one door open a little, turn the knob up to about 350, then when it lit up (after anywhere from 2 to 10 minutes,) I would close the door for preheating. I just figured it was old, original to the house built in the fifties, so something to live with and not too inconvenient. Certainly not a worry for someone like me, who grew up with gas ovens and stovetops.
Now recently, and just in time for Thanksgiving, mind you, the oven has stopped lighting altogether. After following this thread, I am going to disassemble it and try cleaning it thoroughly, to see if that makes a difference. I have the same problem as listed above, the space it occupies now is 24" x 38", not your average size for today's models, and as it sits in a cabinet at the end of the countertop and a doorway, not easily modified.

Allen, for your own welfare, refuse to get drawn further into this situation. You have given your best advice. Scrooge refuses to spend the money. If you go back to do any work and there is any sort of bad effect, you will be blamed and, if there is any monetary loss, he will come after you for damages. Listen to them bitch about it if you have to, but do not do anything more on this oven for these people.

Possible solution for modern gas ovens' (and/or gas cooktops) need for electrical power:

Get a small battery backup system, such as used for personal computers. My gas cooktop has a standard 110 volt line cord and plug, which easily could plug into a battery backup system. I'm assuming a wall oven could have the same sort of connection, or easily be adapted to one.

The battery backup system need not be very large, since the power demand of the system computer control and ignitors is small. And it would only be needed in times when there is a power outage. Probably a good idea not to use the oven light during a power outage, though.

Same occurrence with grill

We have a really cheap gas grill and the Igniter doesn't work so you have to turn it on and stick a match up the hole where the burner is. I turned it on high with the lid shut and I stuck the match up there a few secs later there was a big FOOM! Luckily my hand didn't get burned but when that happend I shut the gas off IMMEADETLY. That would have been a bad one...

It's ironic that this thread popped up again now.

The guy went ahead and replaced the oven two days before Thanksgiving with a new BOL GE oven. It turns out that the wife's bitching exceeded his ability to withstand any more of it. Just as I figured it would happen.

But interestingly he removed the Caloric oven from it's mounting location before the new oven arrived. I asked him why he did that, usually the installers will do that. His response "I didn't want to have to pay for them to remove the oven". Another thing he found when he took the Caloric oven out was that it used only a 1/4" line as a gas feed. So the installers had to replace part of his old gas line.

Coloric Gas Wall Oven Ignation Problems

combo52's profile picture
Faye your Coloric likely needs a new igniter and Coloric also had problems with oven burner ignition if your oven is one with the infrared Ultraray broiler, if your has this burner you need a good techichion who can install the new igniter so it will work properly. Your Coloric wall oven would be from the 70s-80s if it uses a hot surface igniter. Also your experience with a gas grill may not have much to do with your ovens problem if your grill is using LP Propane gas, Natural and LP gas behave very differently.

Rich, a battery backup for gas ovens like we are discussing would need to be VERY ROBUST, these oven igniters consume almost 400 watts of power continuously when these ovens are in full use.

And remember some parts for these Caloric ovens are NLA.

Two questions.....

Allen: Why was the gas line an issue if the oven was replaced with electric? Was there a gas cooktop nearby?

John: Why does electricity continue to feed once the gas oven is ignited?

Electrically Ignited Gas Ovens

combo52's profile picture
Electricity is constantly required to keep the gas valve open, and in addition gas ovens that use hot surface igniters use the cheapest way of doing so. The system uses no sensor to detect when the flame actually lights so they just keep the igniter on full speed ahead consuming electricity at the rate of 300-400 watts the entire time the burner is burning.

Among US range brands ONLY WHIRLPOOL [ used on most WP, MT and Kitchenaid ranges ] has pioneered a system used on their 30" SC gas ranges that uses a spark to instantly light the oven or broiler burner. For this reason alone I sell a lot of WP built gas ranges [ these ranges are built in their Tulsa Oklahoma factory ] I think you will see this type of ignition required at some point in the future because of the electricity savings. I like it not only for the power savings and durability, but I also love pushing the bake button and then start and it lights within 2 seconds, no 30 second ---- two minute wait for the oven or broiler to start heating.

I think that you will soon see oven vents on gas ovens that will close when the burner shuts off, this will not only save gas , but should also improve baking results and keep the kitchen cooler.

I love my gas Whirlpool range.....

for many reasons, this nearly instant oven ignition is just one of them. The only time I have had a baking failure was due to OPERATOR (moi) ERROR. It has been Just That Good, and I would get it again. It has one of the best ovens I have ever owned. I am locally famous for my baking, and people are disappointed when I don't bring cookies or cake to a gathering.

Retromania:

They replaced the gas oven with another gas oven. The owner didn't want the expense of running a 240V line to the oven location. So to do this they had to upgrade the gas service plumbing.

The link shows the oven then installed. I'm just hoping they keep the new oven cleaner than they did the old oven. There must have been 2 inches of food debris on the bottom of the old one.

Oops, my mistake!

I assumed since it said GE, that it was electric. Don't think I have every seen a GE gas anything!

My Whirlpool also uses an electric spark to light both oven and top burners. Oven has the spark lit pilot that lights the burner and relights it as thermostat calls for more heat. Pilot is off when oven control is off. Best part of this system is you can use top burners and oven during a power outage. Another property I once owned had a brand new Brown gas countertop and wall oven. First time it was tested, it blew the broiler across the kitchen because a connection at the oven burner had not been sealed properly at the factory.

Yes, it scared the crap out of me. Big boom and quick flash. Gas tech yelled to shut the tank off quick! Tech figured out what exactly happened and it was fixed. Worked perfect after that. I like the Whirlpool I have now better.
