My CA was frosting at 19-20F but was far too high for it to ever cycle. That sounds like the control is not calibrated correctly. In position #1, it should be able to cycle with evaporator temps warmer than that, up to 27F for CA-2A or 31F for CA-2B. I found that the evaporator temperatures given in the CA manual were quite accurate with regards to matching the specified cabinet temperatures. All of this of course depends on the system being given sufficient time to stabilise and the door not being opened, etc. Your 19-20F is around the middle of intended operating range so it should be cycling. I'd guess the knob should be about 5-6, depending on room temp, for that. In my situation having damaged the calibration, I had to move the knob about 6 divisions to restore it. This was before I did the capillary tube. 19F isn't cold enough to cycle, if I recall you need to drop down to around 12-13F to shutoff on a form A CA machine. I believe half way, my form A machine runs between 8F - 19F.

Well gents, I spent some time on the phone with Jason, the gent who meticulously rebuilds the control boxes... So, I have the control box cover off, phone in one hand and pliers in the other! He's walking me through adjusting the inner spring wheel inside the temp drum. It took a while but, finally got it to a point where I felt it was good... I took some photos and texed them to Jason. He said it looks to him things should function normally. So, I put the cover back on and plugged it back in and switched it on (It was unplugged for only an hour or so, and it was pretty warm in the garage) left it run for an hour or two. I came back after having some ice cream with friends... Checked on the machine in the garage... The DR wasn't running. So, I saw the switch was still in the (ON) position, I opened the door, checked on the thermometer, read about 45oF. Frost on the evaporator everything seemed right. Left the door open for a few minutes... Then it snapped back on and started to run again! Closed the door and let it do it's thing. So, seems like everything is working good. I'll keep an eye on it and make sure she's doing what she should. Thought it was time for some good news.

That is good news! Having it able to cycle should take away the worry of an overheating compressor. Once everything has settled down it will be interesting to see if the cycling times are what they should be.

Update:
I left it alone in the garage last night, seeing that it's learned to turn it's self off like a good fridge. This morning, I checked on it. Wow, it's at 35oF box temp, compressor is warm but no where near hot. Good thick layer of frost on the evaporator. It seams it's behaving nicely. I have no idea what the off time is between on cycles but, this will be known soon as I have a moment to spend in the Garage. Since it has a newer foam rubber door gasket that someone put on it a while ago, it seems to keep most of the moisture out. I'm going to have to replace the original door gasket on my CK because, that machine accumulates ice pretty fast.
Anyway, a hearty thanks to all the insight, suggestions and help you guys have offered to this '29 DR. Couldn't have done it without you guys!
Going to give Jason a call and tell him the good news.

So today, I've been periodically checking in on the DR. I haven't caught it running but, the top is warm, the box is around 38oF or 40oF. It's very warm and humid in the garage so, I'm sure this strange weather we'er having here right now is messing with the poor insulation that box probably is dealing with. But, she's cycling on and off normally it seems. I bought a few bottles of the cane sugar Coke from Mexico, good stuff, very like the original formula, put'em in there. So, now the DR isn't just running for nothing, she's got a job to do! Keep them glass bottles of coke cold!

Is the center of condenser and float tank about the same temp when it's running?

I'll have to snap some pig pics soon. I checked the frost on it today and it's accumulating normally. The condenser coils and float tank feel to the touch to be very similar in temp when running. I was out there late tonight to check on it. It was running when I opened the garage. The compressor top was warm, she was purring whisper quiet. I wanted to see how long it was going to run. So, I switch on the ol' tube radio in there and listen to some Coast to Coast... I failed to bring my watch with me... But, I'm going to guess it ran for probably 20 minutes or so. It shut off... I entered the garage about 1:20am or so. I left the garage at 2am. It still was off and didn't cycle back on. The top was cooling down so, things are well. I'm going to take some photos later today.

congratulations
when they are running correctly the performance is hard to imagine
my experience is most of these old appliances work better than advertised
the quiet performance is hard to imagine
you have a winner there!!!!

Great to hear it is working so well. Hope it lasts for another 90 years.

Gents, I think that's part of the attraction to the older stuff. When it's working right, it's really hard to beat. I'm preaching to the quire here when I say just the sound of these switching on, running, hearing the evaps gurgle, hearing it shut off... It's a special thing that sadly no one really knows today besides folks like us.
I've depended on antique appliances for a while, like a 30s Toastmaster toaster, th e'35 CK and before that the '40 GE I had... And the '46 Plymouth I drove daily. So many things were made so well in those days. People knew the value of a dollar, when the US dollar was worth something. No one wanted to purchase cheap stuff. Even lower priced items worked and lasted longer than some of the modern made nonsense. :/
There's marvels of the modern world, but some of the old stuff just lasts and lasts. It can be serviced, it's wonderful.

Electric fans are another appliance from the last century that will not die.
In the summer of 1969 before I could drive my mother would take me to junk stores in Paterson NJ
For two dollars we bought a black 1918 Diehl fan.I brought it home cleaned it replaced the line cord,
oiled it and it has run EVERY night (even in the winter because now I cannot sleep without the sound of a fan)since that summer. Forty five years,eight hours a night !!!
All of my Teens and Twenties appliances will outlast me.

Oh, absolutely! Electric fans from the 1910s-30s will run forever so long as they're oiled. Those old electric motors will outlast us all. I have '20s GE loop handle fan with brass blades I picked up at a swap meet for $20. All original, also a DC current fan. I found a good bridge rectifier, spliced it into the replacement power cord and it's ran constantly with no problems. They just don't make anything worth their salt anymore.

I own two of these my wife bought me in 2008 which I think is right around when Lakewood stopped making them. They are Lakewood P-23 boxfans and if memory serves they were the last to be made in the USA. The motors have little oil holes on the front and back. They aren't old, but they sure are built like old ones. I also have a 1929 R&M large desk fan, I think 17" or so and sold a smaller 1919 R&M desk fan to a coworker not too long ago. I always sleep with a fan on so quality fans as well as fans with a good sound are important to me. Attachments:

Well, a DR: update.
The night before last, I sat out in the garage and enjoyed listening to the DR purr right along, hear it snap off and I waited about 10 or more minutes waiting for it to cycle back on... I started to get tired and went inside.
I went out this morning to check on things in the garage. The light was out and so was the DR. The ice that had formed was all water on the bottom of the cabinet. I checked the breakers and they weren't tripped. I turned them off and on again... Still no power in the garage. My guess is that the current being pulled by the DR when running was a little more than the light socket had in mind. Yes, there's no outlets in the garage, just a light socket from one rafter over the car. So, that probably killed the socket. I'm going to have the land lord come over and check it out on Monday hopefully. I won't tell him I ran a 1929 fridge for the last week in there. But, will see if he'd hook up an outlet so I can plug my radio and fridge into.
I turned the switch on the GE to "off" so when I do juice it up again, I can give it time to let the heater warm it up again before I turn on the motor.
