Good afternoon, all. Recently aquired a 1929 Frigidaire fridge (yes, 1929, as in 81 years old!!). The mechanicals are all original and it's still running on sulphur dioxide. However, about a week ago, the compressor started making noise and I beleive the compressor has begun to draw some air into the low side when running (for those not familiar with SO2, it's a low pressure refrigerant and the low side actually operates in a vacuum).

At any rate, the reason for my question is this: Does anyone here have an OLD Frigidaire parts catalog that would give a part number for the compressor shaft seal? It's a model AHDP-4840 and the compressor is a model "EF". I know it's a long shot, but old warehouses of vintage Frigidaire parts are not unheard of. BUT, I need a part number to start. Thanks everyone!!

Can't help with a part number but just want to say that those are some really fine looking refrigerators.

Any pix you can post of it here?

Model # of the fridge

I think you'll have to have a seal made. I would fall over if a parts house had these. I saw one in a box once. The problem is finding them before someone tosses them.

Model is AHDP-4840, Compressor Model is "EF".

Yes, well aware of the nasty nature of SO2. Plan to bleed the air of very carefully into a bucket of lye water, wearing an acid vapor cartridge respirator and all of the other necessary safety precautions. Definitely nothing to be taken lightly.

SO2

Sulfur dioxide is pretty toxic, but it is a wonderful refrigerant!

And inside...notice the maple trim!!

Story goes as such: Unit delivered new to a railroad depot in Iona, MN. Spent most of it's life there (and obviously very well cared for). When the depot closed, an employee there purchased it and it was used as a spare basement fridge until 1994, when it was taken in on trade(!!) at a Frigidaire dealer in Lakefield, MN. I purchased from him two weeks ago. The porcelain and trim are flawless. The top comes off and on the bottom side of the top it still has chalk inspection marks from the factory!!

Ah, yes. I remember almost buying one of these many years ago, but repair was so much more complex than just switching tops like with a GE of similar vintage. Aren't these Frigidaires belt-driven?

They are much more handsome than Monitor Tops IMO.

What a beauty, and a rare find for sure. Good luck with it!

Thanks to all for the kind replies - I fell in love with it for all these same reasons. The condition is almost museum quality. I'm really hoping I can keep it running. That's a bit more challenging because yes, unlike a Monitor Top, it uses an "open" type belt driven compressor. Lots more opportunities for leaks than a hermetic unit. However, there is one upside - it's actually (as long as you respect the SO2 and think things through carefully) much more serviceable than a Monitor Top for all the same reasons. It has liquid and vapor shut-off valves at the receiver, compressor, and evap coil. So, as long as the valve packings don't leak, you can actually isolate and pump down any of the components using the compressor and service them without discharging the SO2.

While about 40 years apart in age, it doesn't look too bad next to my 1969 Frigidiare Custom Imperial "eye level" range (RXE-39P) that came with the house (eye level glass control panel, similar to a Flair). Which brings me to another topic - I've seen ads for a matching circa 1968 / 1969 Frigidaire Laundry Center pair with "eye level" controls, but I've never seen a set. Perhaps it never made it to production? If so, maybe it was so costly that people didn't bite? If they ever did make it, it must have been short lived. The ad I'm thinking of (Life?) shows a pair perched in a loft above a very "mod" late 60's open kitchen. Avocado set - both the washer and dryer look like standard models of the day, except with a hood over the top, with what looks like a cabinet at the rear for detergents, etc., and glass control panels at eye level (ala Flair)

Those look like a pair of pull-out ice trays to me. The rest of the unit is just the evaporator, so no freezing compartment other than the slots for the trays.

That's my guess, anyway.


Post# 478989 , Reply# 21   12/2/2010 at 15:46 (4,887 days old) by scooter76 ()        

That's correct - two aluminum ice trays slide into the evap coil, that's the extent of what you can freeze!! I guess one has to remember this was before the days where frozen foods were commonplace. You went to the store every few days, bought fresh, and ate it before it spoiled.

Well.....

in the 1920s-40s, there were a surprising number of recipes written for frozen desserts that started with "take out the grid of the ice tray, and turn down the temperature."


Some of these recipes were, of course, from General Electric, or Frigidaire, or Kelvinator, but even otherwise reputable sources, like the 1931 Joy of Cooking had some.

I think it's very interesting that recipes were already taking advantage of frozen dessert options back when freezer volume was no larger than what two ice trays could hold. Talk about impressing your dinner guests!

So Scooter, was the fridge kept running after it landed at the dealer in 1994 or did it sit until you bought it? I'm wondering if this is the classic use-it-or-lose-it scenario, or a case of entitlement after running continuously for 81 years.

What a wonderful machine!
And in such a perfect preservation state too!
I guess it can't be refilled with a modern refrigerant, isn't it? (unless swapping the cooling circuit of course)

Can I ask what are the power/current/voltage ratings on the compressor?


Post# 479208 , Reply# 25   12/3/2010 at 13:30 (4,886 days old) by scooter76 ()        

Unfortunately, I'm not aware of another refrigerant that will operate at such low pressure differentials. It may be possible, but I'd have to convert the cold control to a thermostatic system - it works now off of pressure - there is a barometric bellows in the low side suction line that kicks the motor out at a certain inches of vacuum and kicks it back in at about 5 lbs. pressure.

IIRC, the motor is a 1/4 hp, 5A.

Steam boiler stuff?

volvoguy87's profile picture
Look into a vaporstat. A steam boiler runs on very low pressure (heating steam). A steam boiler is turned on and off based on pressure. Normally, this is controlled by a pressuretrol, but it's accuracy isn't good enough to deal with ounces too well when one ounce matters. A vaporstat, however, can detect that kind of small pressure changes and can open and close a circuit to control a boiler's burner. Perhaps, if needed, a vaporstat can be used in your refrigerator.

Clear as mud?

Well Chris, that's another beautiful Frigidaire. They really do seem to be the nicest looking early refrigerators, at least in my opinion.

Travis checked in here early on with reply #3 above. I agree that if there's anyone among the membership who can provide assistance and guidance, it's him.

I also think Dave's suggestion of a vaporstat is a great alternative. I would really like to see Scooter get this thing up and running. The way it was constructed, it's got many years of cooling still ahead of it.

Hey Chris...that '34 model is beautiful! What's the refrigerant? Is it R-114 or R-12?

Latest development that has me somewhat puzzled: I let the unit sit for about a week and turned it on again - it still exhibited the knocking / hammering sound, so I shut it down. On a whim, a day or two later, I turned it on and it ran perfectly quiet, just like it did when I got it(?!?) It ran through three on/off cycles over about an hour’s time, then the noise returned again. Oddly, it did not come back while it was running – it was humming along quietly, kicked off, then was knocking immediately when it kicked back in again. So, I'm totally baffled. The only thing I can think of is maybe the screen on the receiver end of the liquid line is sucking up some rust or other crud. Liquid flows up that line even when the compressor is off, as soon as the float in the evaporator calls for more liquid. This restriction is, perhaps, causing an abnormally high pressure in the receiver, which is in turn raising the head pressure and causing the knock? Obviously some liquid is getting through, since it does not seem to adversely impact its ability to cool – the coil is still freezing cold. But, whenever it’s knocking, the head and discharge line from the compressor feel somewhat hotter than I think they should, so that would somewhat make sense. I’m guessing that, eventually, the crap fell off and allowed it to briefly run normally again before it again was sucked up? Regardless, I’m now thinking that maybe air has NOT gotten in after all. I really hate to take the caps off of the service valves and start turning them or it WILL definitely start leaking. But, then again, it isn’t very useful as it stands either. Maybe Travis has some ideas?

This just made my day , Thanks for posting .

I`ll always remember the 1st time I had the opportunity to see the motor room (Refrigeration room ) of an old super market & remember seeing a few belt drive air cooled condensing units still at work - I fell in love at that moment - Over the past 26 years I have managed to save 15 belt drive air cooled refrigeration condensing units from the scrap yard & also have 3 refrigerators like youres That use the belt drives , You are soooo lucky to have a working unit as all mine either have locked up compressors or burned up fan motors .

The seal will more then likely have to be made - As far as sulpher dioxide there are people out their that have the old gases - I met a man in New York years ago who collected old chemicals & had several bottles of the stuff I forgot his name.

Congratulations !!!!! I`m drooling :)

Forgot to mention.

I hate to say this but if I were you I would keep it original& use it as a static display & keep in mind that the unit could always spring a large leak or the motor could catch fire while youre away If in continous use.

You could always fire it up only when you have guests over .

Just a thought.

I have the same ref that you do except it is the wider two door model. We bough it at an estate sale around 1980 and after exploring different ways to fix the leaking compressor shaft seal we just converted it an R-12 system around 1981. It has been working perfectly all these years, I will try to find some pictures of it to scan as it is in my mountain house in WV. If you want to E mail me your ph # I will let you know how it was converted John.

Douglasdc: I would love to see some pics if you have them of your belt drive condensing units. I am a refrigeration technician for 37 years and when I started back in 1973 alot of grocery stores still had the belt drives. I loved those units and very partial to the older stores.

Post# 486503 , Reply# 36   1/5/2011 at 09:07 (4,853 days old) by scooter76 ()        

Spin-it: Out of curiousity, do you recall what the belt drive units sounded like? Were they noisy? I did some work to mine over the holidays - I think the evap was oil logged and perhaps starving the compressor of oil. This was likely caused by a stuck float valve that was admitting the refrigerant to the evap as a vapor rather than a liquid (no back pressure on the liquid line to keep it as a liquid). With low liquid level in the evap, it could not reach the oil return hole (oil is only slightly soluable in SO2, so it floats on top).

So, it's running again, but there is still some noise evident. Not a loud hammering, but a definite muffled "chunk-chunk" (like an air compressor) but much quieter. Obviosuly there's likely to be wrist pin and crank wear after 80 years, but I'm wondering if some of it is normal? I've never heard another one run, so I have nothing to compare it to.

Maybe you've seen this...

Perhaps some of you have seen this, but a very interesting photo of a Frigidaire display from 1926 (looks like it's sitting in storage after the event, but obviosuly the heavily frosted "Frigidaire" coil and evaperator units indicate that they were running at the time the photo was taken. Also note the water chiller / drinking fountain on the left. In addition to home refrigerators, Frigidaire was heavily involved in commercial chilling units for drinking water, ice cream freezers, beer coolers, etc. I believe they also sold packaged units for retrofitting the old wooden iceboxes as seen in the photo...

That "muffled chunk-chunk" description brings back childhood memories of a belt-driven refrigeration unit at a neighborhood mom & pop grocery store.

I'm no expert, but it could be that your fridge is operating as it should now, with slack allowed for some additional mechanical noise after having been in nearly continuous operation for over 80 years. No doubt the "use it or lose it" postulate has been a significant factor regarding your machine's longevity.

If you're like me, you probably won't be satisfied until you've exhausted all options to quiet it down further, and I would not be surprised to subsequently find out that you were successful.

Congratulations, and keep us posted!

I have to say I have never worked with SD refrigerant, all the units I dealt with were R12 and expansion valves, from the early 50's. I have worked with high side floats on a limited basis, if the float is stuck closed it will not admit liquid to the evap and it will "pump down" and cycle on the low press. control. If it is open it will admit too much liquid to the evap and could flood liquid to the compressor, not good and quite noisy.
I remember old A&P stores with a whole row of belt drives lining the basement back wall, usually water cooled, one compressor for one, maybe two display cases. R12 was a great refrigerant used for medium temp or freeser temps. Those were the days! I have no photos but would love to see any that other members may have.
Beautiful vintage refrigerators by the way.

belt drive compressor

a local cafe still runs it's belt drive compressor for the
walk-in cooler;the cooler was put in in 1940 and is insulated
with cork.The motor is fairbanks-morse and the condenser is
air cooled with a single fan on the motor pulley(i have seen
larger ones with a belt running to a 2nd fan)
only part not original on the cooler is the evaporator as the
original had to be replaced because of corrosion.
BTW i did take a few pics of the compressor-if i can find them
i will try to get them up.

Need Advice on similar Frigidaire Refrigerator

Hello! I'm so grateful to have found this post here and am wondering if there is anyone who could help me identify the date/model of this refrigerator and any advice for restoring it. I bought it from the family of the original owner but I don't believe it works, and based on what I've read here I'm concerned about safety issues. The outside is really pristine! Have not been able to find anyone locally (Washington D.C. area) who knows anything about restoring them or is even willing to touch it. Thinking that the best and safest thing might be to replace the refrigeration system. I intend to use it, am restoring a kitchen in a 1917 row house. Appreciate any help, advice or suggestions you might have! Many thanks.

Don't get ahead of yourself just yet.

The refrigeration system might be just fine. My 1939 GE's system certainly shows no loss of performance or efficiency. With the refrigeration system, I'd leave it alone if possible. Replacing or modifying the refrigeration system would be expensive and likely wouldn't result in any improvements in performance or reliability.

In order to make your refrigerator safe, you may want to replace the cord. I'd also likely connect a ground wire. In order to make it a well performing and efficient machine, you may need to replace the door gasket. Door gasket material can be purchased from www.antiqueappliances.com....

Old refrigerators, such as this, tend to be simple and very reliable. Most mechanical problems have to do with the thermostat and compressor starting mechanism (relay or similar). Surprisingly, really old refrigerators, like this one, are also pretty energy efficient.

Best of luck,
Dave

I'm no expert , but here is my experience

swestoyz's profile picture

The original compressor is more than likely a belt-drive unit, very similar to my 1936 Frigidaire.  The refrigerant type was SO2 in the mid-30's, not sure what stuff would have been factory for '27, but it certainly wouldn't be very safe (either Ammonia or SO2) to expose in a contained area, i.e. inside the house. 

 

These systems aren't sealed in the sense that the GE Monitor tops or later GM Frigidaire Meter-Miser compressors were.  There is an actual separate compressor that looks very similar to a pneumatic air compressor pump, with a motor driving the pump via a belt.  The shaft seals can leak over time, and/or the head gasket, etc. 

 

The chances of the original system being intact with refrigerant are probably pretty slim, but I would be quite cautious plugging this old girl in just in case it still is charged up.  If you are not comfortable working with these unknowns, I would suggest continuing the search of finding someone who is and has an extensive background with refrigeration equipment.  Unfortunately, most folks in the industry these days haven't seen a belt driven pump before.

That's a 1930-32 Frigidaire

That's a nice looking fridge.  If it's original, it's an so2 unit and belt driven.  These belt driven compressors rely on refrigeration oil to lubricate and help seal the shaft seal.  What happens is the seal dries out, the so2 starts to leak.  The leaking so2 contacts moisture in the air and creates rust and further destroys the seal.

 

When I have found a refrigerator like this, the compressor pulley is usually frozen solid.  You don't want to play with these in your house until you know it's ok.  If you have to break the pulley free with your hand or a mallet, you better be ready to turn on the motor and back away.  There may be a charge left.  The shaft seal may seal itself in operation.

 

I got a 1935 Kelvinator last week.  I saw the belt drive unit and figured I had a hunk of scrap.  I was shocked when I turned it on to find that it runs and cools just fine.  That was a first for me, in a dozen purchases.  It's possible to use R12 in most of these.  You can compensate for refrigerant differences by changing the motor pulley.

 

If the belt drive compressor leaks, you can have a refrigeration man install a new compressor but keep the original evaporator.

SO2

Is a GOOD refrigerant but is a nasty smelling one, it can kill pets, especially birds, and will cause all exposed metal it comes in contact with to rust, in a sealed system like a Monitor Top you probably will never have a problem, in this I would have a old time refrigeration man check it out before I used it...its not going to kill you, but its also not a nice experience..trust me, you wont stay around it long if it leaks!!

First off, Hello Lauri! And a big welcome to AW!! That is a neat old beast you have there and it looks to be in nice shape.

Personally I would not run that unit if it had Sulfer Dioxide refrigerant inside my home. At the vintage of that machine, especially if it sat long, the compressor shaft seal would be quite suspect.

Up thread (Reply #33) is a post from my brother John. Back about 1980 he and I and another brother Jeff found one of these at a DC estate sale. After purchasing the unit we moved it out back and while checking it out Jeff turned over the compressor pulley to see if it were free. The unit immediately started to leak the pungent SO2 refrigerant. We knew it was unsafe to load it into the van and drive home with it. We cracked a fitting and left it there for the night and went back the next day. Even with the little exposure we got to the refrigerant that day we all developed a cough and minor respiratory issues for a day or so. SO2 is NASTY stuff. The Ivy on the garage wall at the home of the estate was burned by the vented refrigerant also!

After we got it home I remember pulling out the condensing unit and cleaning and painting it. I think we were sure that the original compressor would never be used again, especially for SO2. I remember in the pre-Internet days trying to find a little info about a shaft seal and Freon swap. Perhaps today in the information age it might be easier to find a part to sub but this could require a full compressor rebuild, a machinist and lots of crossed fingers.

Eventually Jeff soldered copper tubing to hidden surfaces of the original evaporator and used a modern (in 1980) R12 compressor/condensing unit to provide cooling. The condensing unit was installed remotely in the room behind where the refrigerator was placed in John's West Virginia cabin. It was an awesome resto-mod since the unit appeared to be fully stock. The original compressor could be switched on so as to hear it run also. The unit ran for many years in place, but I believe that John has since sold it.

Perhaps you could end up doing something similar with your unit if you were so motivated. John and Jeff both do active appliance service in the DC area, you may want to try making contact. Look up Alco Appliance in Beltsville and Jeff's Appliance in Adelphi. I'm sure that just about any other service company would all but hang up on a unit this far out of warranty ;) There is something satisfying about seeing one live on!

Story about SO2

My Grandparents got electricity in 1938 and were the first on the street to have a refrigerator, it was an Apex believe it or not, sometime during ww2 it leaked and ran them all out of the house, when it was fixed it went OUTSIDE on the back poarch!!!! it leaked again in 1950 and a new big Westinghouse replaced it IN the kitchen, our next door neighbor got a Norge in 1940 that lasted until 62 and was replaced by a Coldspot, Bertha and Raymond, the neighbors in the 3rd house got a Frigidaire in 39....its still running in her great neices basement with out any repairs...NOT ONE SERVICE CALL!!!!Frigidaire by this time had Freon and the Meter Miser Compressor!

SO2

volvoguy87's profile picture
In a sealed system, Sulfur Dioxide is okay. My '39 GE is SO2 and is running just fine.

It may be possible to convert from SO2 to something a little more common, like R134a, but I've never done it. Bear in mind that appliances of this era were designed to be repaired, rebuilt, and serviced. The compressor can be rebuilt, seals can be replaced, even he electrical contacts can be serviced in many instances.

SO2 is indeed nasty. If contained, it's fine, but if it leaks, you'll know it! Many refrigeration leaks are caused by user error (defrosting the freezer with an ice pick, for example). Even with a compressor oil change, some contemporary refrigerant, and some new seals, the original equipment may still provide fine service.

Dave,

What you say about replacing seals is true in theory. The problem is that the original manufacturer is gone on these. Finding a suitable seal for a compressor is much more critical than replacing a seal on a washer or dishwasher.

I had asked Mike Arnold about converting one of these to 134a. He felt that I would never be able to get all of the old oil out of the system to do that.

I assume my Kelvinator uses so2, but it could be R12. I won't let any of it out and stick my nose down there to find out. Just a tiny amount will run you out of the room. I agree though that this fear of so2 is overblown. Don't defrost with a sharp object and it will stay inside where it belongs!

Yeah, that SO2 is some nasty smelling stuff, once you get a whiff, you won't forget it!

I realize this is a very old thread; but I want to place this info here since it may help someone else. It is possible to modify these compressors to use the shaft seal from a modern General Motors automotive air conditioner compressor.

I recently restored a WP-6 with a similar compressor. To fix the shaft seal, I turned the compressor shaft down to the same size as the automotive compressor shaft; and then turned the automotive compressor housing down to make an adapter to put the new seal in.

Hey cuffs054 thanks for the compliment. I want to post a thread about the whole Frigidaire restoration but this forum isn't letting me post a new thread. I'm sure it's my laptop; or I'm doing something wrong.

cuffs054, I was able to start a thread here which I think you've foundlaughing.

 

Just dropping the link here so that people who search and find this thread may follow through to mine as well. There is so little info out here on these units, I want to be sure the info is found.

Also, I wonder if the original poster ever got his part for his Frigidaire?
