That's a dark blue porcelain coated evaporator. The same as some FEA's and some rebuilt units.

The serial # proves it is a 1942 model. I never knew the porcelain evaporators made their first appearance in 1942 at the start of WWII. I thought the 1944 FEA was the first to have it.

I wonder if it was a factory (or field) repair part which had been installed on that unit? Travis mentioned that rebuilt units got those as well.

I found this picture of a 1942 GE refrigerator and it does appear to also have the porcelain evaporator. I am led to believe that for at least part of that year's production they transitioned to porcelain. www.flickr.com/photos/lucysquilts/2849784334

They probably couldn't get stainless steel. This is likely one of the last fridges made before war manufacturing took over.

I believe we read somewhere before that hey had to switch back to non stainless steel evaps and cloth covered wire because of war shortages.

Yes, I have two wartime produced FEAs that use R12, blue porcelain evaporators, and cloth wire.

I'm assuming the cloth covered wire is still intact? Or does that have problems at this point as well?
I'm really curious why it seems like GE kept going back and forth between R12 and SO2.

.....curious why it seems like GE kept going back and forth between R12 and SO2. Chris, if I gather correctly from my reading; GE engineered the scotch-yoke to work with a non-miscible oil and refrigerant combination such as mineral oil and SO2. They had some difficulties using R12 since it mixed with the oil and caused dilution and other difficulties. They tried it in a couple years of flat-tops and maybe a few CK machines then went back to SO2. The FEA was engineered from the get-go to be used with R12.

My cloth covered wire is fine. In much better shape than rubber would be at this point. The connections at the evaporators on the other hand…dubious at best. Very rusty.
