hello all, i have a 1935ish (5141575) CK-2-B16 with what i believe a faulty starter relay. this has been in my shop for years, and remember buying it with my late father some 30 years ago. last summer i went to the shop and noticed a puddle, i recycled power. it ran and cooled fine but never wanted to turned back on from tstat. this past weekend i installed the Supco RO81 Relay and wired it per many threads on the subject as: a/c line white goes to one of the smaller black wires on the supco relay a/c line black goes to the compressor black
supco white goes to compressor white (starting) supco red goes to compressor red (running)
well it ran, but that relay got hot!!! to the tune of nearly 180 degrees. my current/factory? relay is below, did i miss-wire it? '

Hi Carl. Welcome to the forum!
It does sound like your original relay has stopped working properly, if the Supco got it running again.
The Supco relay was wired correctly, it seems. The GE service manual shows that White on the original wiring was start; and Red was run. That matches up with your connections.
Now; it is normal for the Supco relay to get very hot. It is actually a thermal timing device, and not really a mechanical relay. The start circuit passes through a "PTC resistor." This device has a low resistance when it's cool; and a very high resistance when it's hot. The start circuit current flows through the PTC material, and tapers off to a fraction of an amp, as the device heats up. It will be too hot to touch while it's energized.
The main thing to watch for is that the motor's current draw is within spec. Please hook up a current meter and be sure your motor is running on only the run winding. That will eliminate any chance of damage.
Many of us like the P3 "Kill-A-Watt" meters.
Sincerely, David

What he said. Glad that you were able to find the information you needed. Hopefully you can get it to run for many more years to come.

Awesome! The patina on that fridge really makes it a great workshop fridge / transmission jack storage place!

It seems there are many styles of hardware on these cabinets. Anyone who has a stash of parts would need detailed pictures of the remaining parts of the handle, door hinges, and other cabinet hardware details. Over the years, people have mixed and matched cooling units and cabinets. The waters are often quite muddy, when it comes to knowing what parts you have based on a model number etc. Pictures of the remaining parts, and other parts of the same cabinet are really the only way to identify.
I know Travis has a few cabinets which may be parted out, so maybe you could contact him about it. There was a CA with bad cabinet and broken line. I got the CA top to fix, but the cabinet was to be parted out. I don't know if it's the right handle; and he could already have sold the handle, but it never hurts to ask!
Sincerely, David

That’s a normal 35 CK cabinet I believe. Those handles aren’t near as substantial as the ones that preceded it. They are hollow instead of solid. I also love your VW. Very cool.

Hopefully someone can locate a better handle. In the meantime, maybe a repair is possible. Seeing how that is a stamped steel handle; it would be possible to repair it by soldering / brazing. I had a similar failure on a Westinghouse handle and was able to make this repair. See the 6th picture on downwards for the repair. monitortop.freeforums.net/post/22924
