I am trying to help a friend with their dead 1950's Frigidaire. It's a DM 107. It uses a YT relay, also part # 6580937.

Here are a few pictures.

Travis, did you try contacting that fellow Mark (simplicity345 is his screen name, I think)? He seems to have a stash of NOS Frigidaire parts.

If not, try Affordable Appliances in Pennsylvania or Angel Appliances in LA. I found a LOT of places who have old refrigerator parts when I was struggling to bring the '56 GE wall fridge back to life....
 
That IS

A 1950, I used to have one just like it, Like all Frigidaires of that period, it won't keep ice cream ,but really great for fresh food.I had to replace the relay on mine also, i loved to hear it start, it revved up for a couple of seconds before settling down into that wonderful Meter Miser sound.it kept milk and tea colder than anything made today.
 
I think I found a relay.

 

My grandparents had a 1951 model.  I never had trouble keeping ice cream in it.  I compressors on these are virtually silent.
 
Did you get the relay? I have a few YT relays but none with this part number. My parts book gives me the part number 5876896 for a DM-107 (I thought I'd have one of those but I haven't found it). 
 
I did find a relay. I installed it last weekend. The fridge runs fine. It took awhile for the coils to get cold. I think it's been off for the better part of my lifetime. I am told it's fine now. Not bad for 63 years old!
 
Coils Took A Long Time To Cool

Frigidaire and Whirlpool-Seeger refrigerators used Hi-Side Rotary Compressors and when left off long enough to totally cool down the Freon migrates into the compressors oil so the compressor has to fully warm up for the heat to drive the Freon out of the oil, and this can take 30 minutes or longer because the compressor is not doing any serious pumping  [ it is like a system running with no refrigerant in it ]. On piston type compressors the compressor shell [ containing the motor and pump and oil ] is in the low side of the system so when you start one up that has been sitting unused for a long time they still start cooling quickly because the compressors vacuum PULLS the Freon out of the oil quickly.

 

Often rotary compressor refrigerators would get diagnosed as having sealed system problems because of this slow start up process. Whirlpool made smaller window A/Cs that used the WP RC and when you took a new one out of the box and installed it it took a good 20 minutes for the thing to really start cooling. I remember installing a few of these for a customer back in the early 1970s and when I installed the first one I told her it was defective and she took it back to Sears an exchanged it for another. After the 2nd one did the same thing I realized that this was the way they behaved and those A/Cs went on to last nearly 20 years.
 
John,

Thanks for the explanation. I could feel some cooling in the corner of the evaporator after 5 minutes. I figured the slow cooling had something to do with the design. This was a 1949 house and likely the original fridge. It's likely been moved once, to the basement.

The homeowners like this fridge. It's nice to find someone that appreciates older appliances. They had already paid some appliance repairman to come and diagnose the problem. That invoice listed the wrong model number. No wonder it never got repaired.

Where did you find the relay for this fridge? I have the exact model fridge and believe that is the part I need to get it back up and running. It's been working fine for a while, but recently stopped cooling. The same thing happened about 6 months ago on my kitchen fridge and I am pretty sure the relay is my problem.
 
Charlotte,

 

I found a relay through a long search on-line.  I have sent you an email, since I have a couple extras.

Hello!
I have a vintage 1951 MD-71 Frigidaire that needs a relay replacement. It has a 1/8 - 1/9 hp (120v 50/60 CY)compressor. I believe it needs relay part no. 5876896. Do you have one, and am I correct with my assumption?
Thanks!
Brian
 
Brian,

 

Are you the same person, also in Texas, that I have emailed earlier?

 

These relays are available on ebay.  Just type in your part number and there you are.  I have a couple of these.  I would be happy to sell you one.

 

If you didn't receive my email, let me know.
