Maybe it's done for.

I had it happen on and off over the years with no problems but I think the hard one was a few hours later that did it. I have the temp controller separate. I had it wired also so the unloader would kick in if needed. I had an on /off switch in it also where I could turn off the power to the motor but keep the heater going when I would defrost it. The IT100 all it was used for was on and off to cool. It worked for 3 years without a problem and it does look like the starter coil is gone in a dark brown almost black. I won't know till I get it into my shop which is a choir in itself.
I was lucky When I did the charge I found a used 30# cylinder on e-bay it only had 28# in it then. My self I would try R134 and work the capillary tube length if I could not find R11. I sometimes refill and fix the small under-counter frig with R134 but they call for it.
Kind of looking if the compressor motor is bad, I was looking at removing it and installing a newer compressor into the cavity hooking it into the cooling coil. Does anyone know if this has been done? I also have another 1932 CA with a bad compressor which I know is bad. I put an Anni2 on it at 220v trying to unstick it and nothing.

Yes, what he said. R134a is not anywhere near what a CA can handle. Way too high of pressures that it runs at. The poor CA would just stall.

I honestly wouldn’t even feel comfortable running a DR with it. A CK might be ok. I know they ran them on R12.

I want to try and make a "layman's explanation" with some simple math; as to why the refrigerants talked about above will not work for a CA machine.

Try to think of refrigerant as a "swarm of molecules" buzzing around in a cloud.  Each molecule can take away a small amount of heat when it starts to fly around. Therefore each molecule does a small amount of work. All of them together add up to do the total work of the machine.

Gases at a higher pressure have more molecules crammed into any given space.  Gases at a lower pressure have few molecules in any given space. 

Since we can make a simplification that it takes a similar number of molecules to move a similar amount of heat - then it can be said that you need to move a high volume of gas at a low pressure, to do the same work as a low volume of gas at a high pressure. 

High pressure refrigerants are pumped by a compressor with very small displacement per horsepower. This is because there are a lot of molecules of gas, and a lot of work is done by each cubic inch moved by the compressor. 

Low pressure refrigerants require a compressor with a higher volume displacement for any given horsepower. It takes a larger volume of gas to move the same amount of molecules, at a lower pressure. There are less molecules in each cubic inch of the lower pressure gas, so it takes a larger "stroke volume" to move the same amount of material.  Therefore, low pressure compressors have very large displacement pumping mechanisms. 

This means that, if a system is engineered for a very low pressure refrigerant such as methyl formate, it has an extremely large pumping volume per rotation of the motor. This large volume allows it to "capture" enough of the sparsely populated, low pressure gas molecules. It can capture enough to provide appropriate load on the 1/8 HP motor in the CA machine.

If you replace the low pressure methyl formate with a gas operating at a higher pressure, it will "capture" too many of the densely-packed high pressure gas molecules in each stroke. This will call upon the compressor to do all the work necessary to compress and move that level of heat capacity. It will be more than the motor can provide. The result is that the motor will simply stall. 

If we look at the GE manuals, the pressure of SO2 at 15°F is about 0.5 PSIG (14.2 PSI Absolute)

Looking at the CA manual, the pressure for methyl formate at approximately 15°F is 25.2 inches mercury vacuum (2.36 PSI Absolute)

R134A temperature-pressure charts show that this refrigerant at 15°F has 29.7 PSI Absolute.

If you go by pressure-temperature chart only and ignore all other factors such as gas density at standard conditions; and heat capacity, you can see the following picture.

Methyl formate versus SO2 gives SIX TIMES the pressure the compressor was originally designed for.
Methyl formate versus R134A gives a 12.6 times pressure increase over what the compressor was designed for.

There is a significant engineering margin in the compressors and motors of these early machines. A T/P chart change factor of of 2x is not outside of the realm of possibility, considering how other factors play into the system performance.   However, comparing methyl formate to any of the traditional refrigerants used in other system retrofits is clearly outside of anything the compressor is capable of operating with.  When you see that the difference in pressure-temperature chart alone would cause a 12 times increase above the design point; there is no reason to go any further investigating this for a methyl formate replacement.  

In summary; high pressure refrigerant needs small piston and big motor. Low pressure refrigerants need big piston, small motor. This displacement to HP ratio is set when the compressor is engineered, in the physical size of the moving parts. Unless you replace the compressor, there is no getting around this. There is only a certain engineering margin in which the compressor can safely operate. Monitoring it for operating current and temperatures gives some indication as to whether or not you are exceeding those margins.  If the deviation from design is too great, the compressor won't even run.

David

That was quite an explanation David thanks ! 
Are you an engineer or just have a working knowledge of these things? 
Some people are what I would call gifted , or intuitive ,  individual that can not only understand , but break these things down so others can understand also ! 
You seem to be one of them to me . 
I’m glad you’re sharing your knowledge! 

I can repair those relays. Please send me a PM if you want.

Finally getting around to do some checking on my frig top. One question would it be ok to turn it on its side with the R11 freon I have in it? I need to get to the wiring and heater.
