In corresponding with this member, it seems the bellows has lost its charge. I am suggesting he manually close the main contacts to see if it runs and cools. That's good that there is still hope. Will be watching out for a positive outcome!

Success - so far. At least I got this running and it makes that beautiful quiet compressor sound. My main contacts weren't closing so while looking at the bellows I discovered by adjusting the tempurature control (which loosens and compresses the main spring) the main contact would close. I'll still need to determine the correct starting point for that adjustment so please weigh in. I'm a happy camper and thank you Travis and Kevin.
Keep buggering on....

Let it run awhile. Also, when you turn it off, keep the cord plugged in so you keep the heater connected.

I’m very glad you got it running. Now the real fun of getting it to work right begins. At least you know it lives!

Yes - the vital signs are there.
I was just reading in the manual about a good starting point for the temp control. I'll set that and let'er run for a while (after having it plugged in for a while to warm the oil).
Can someone please explain to me what the cycle of operation is in terms of what happens in the control unit? It looks like after the fridge reaches optimal temp (cold) the bellows will contract, the main spring will expand, the main contact will separate and the compressor will shut off. Then when the temp decreases (warm), the bellows will expand, the main spring will compress, the main contact will come together and the compressor will start again.
Is this right???

Thanks Travis.
I found the temperature control adjustment procedure for my control (CR-1050-E) in the manual so will start there. Then I will check the adjustment of the overload protection.

Great to hear that it runs!!

So I've been running the unit but am finding that I am not able to get it to operate automatically - i.e., turning on and off to maintain proper temp. This is what I have tried:
When the inside temp gets down to about 38F I turn the temp control until the unit turns off. But after enough time, the temp will rise back to room temp without coming on. Then I turn the temp control just enough until it turns on but then the temp will go down to below freezing without turning off.
I've read the control adjustment section of the manual and would probably benefit from reading it again.
Any suggestions for troubleshooting this?
Thanks

Partially disassemble the control and clean it

Yeah, it sounds like if your control knob works at all that something is sticking. Take a look at all the moving parts and clean them and then lube them. That might help.

It's great that the cooling unit runs and cools down to those temperatures. Hopefully you can get the control fixed. I wonder if you can tell if the bellows has lost its charge, so that it does not expand and contract with temperature any longer?

By the way, I have had good luck with LPS-1 for lubricating my DR1 control. Spraying a little bit on the control made it dramatically smoother, and it didn't leave a discernible residue.

I am suspect of the bellows. Whats the likelihood of finding one?

You don't have a bellows problem if the control operates when you adjust the temperature adjustment. The controls have have moving parts which require some lubrication, or at least to be corrosion free.
If anything, the sensing tube is loose in the clamp on the evaporator and can't read the temperature properly. I believe you had the control off already.
