Sorry your have problems with your cr , I have a doa dr if some parts will help. I don’t have any CAs but some DRs , CKs . I like the way you set it up for a keg with the taps . It can still be put back to a refrigerator.

This is what happens when you have a top from a 1932 Monitor top refrigerator and you can't move it out to your workshop by yourself. So you do the next best thing move your workshop (partial) with an engine puller into your kitchen. It's hell getting old but you adapt to it the only way you can. LOL LOL about engine puller in the kitchen! That is how you have to do it sometimes! Hope to hear some good news soon about your unit.

UPDATE MARCH 2024
It's been a while since I messed with my stuck CA top. I finally got around last week to cuttings out the compressor motor. I did a test on it when it first locked up with my Anne II and as soon as I flip the start 110V it would throw the breaker in the Anne. Cutting It was not a real bad job just need the right small cutting wheels and air and electric small hand grinders and patience. Once out I inspected and it would not turn any way I tried. I sprayed some penetrating oil between the stator and armature And let it sit over night. the next day I finally got it to turn, tight but it did turn. Dissemble was not a big problem and it took me 4-5 hr removing things carefully so not to brake anything and stacking parts and in order with pictures. After a good cleaning I inspected the parts. The pump parts all look and felt good with no scratches or grooves in or on any of the moving or stationary parts. No copper showing or worn shaft. STATOR or the Coil winding. The winding look pretty good it is not burned as I though it would be there is no smell what so even. Some of the material like cloth is coming off really easy but no burnt wire or insulation that I could see nothing melted together. OHM Readings: here is what I got from doing the coil readings.>Being that 1 is common, 2 is Start, 3 is Run. 1-2 18.3 ohm, 2-3 7.0 ohm, 3-1 26 ohm. If I am reading right the coil is good. The armature look and tested ok also. Only thing I am not sure on how to clean the coil and with what something that won't remove the insulation. I am going to clean it up and oil it good then set it up to run just to see if it will turn the way it is suppose to. If all checks out reinstall it and weld it back up and see if it will run. Also since the coil look and checks out ok should I use it or maybe get it rewound?

It is strange that it was stuck, and tripping a breaker (both of which can be symptoms of burnout). The resistances indicate damage, which goes along with the breaker tripping. With the cotton winding insulation, you can clean it with any solvent not containing water and it should be fine; but I wouldn't be too concerned since it's done for already and needs to be rewound. We are having forum space issues for pictures, unfortunately. Sincerely, David

Dave, do you know a vendor who might be able to rewind the coil for me? Thanks, Jack.

Humm, I found a vender that will rewind the Stator for me up in Cincinnati OH, but he said to just start the price would be $1000 and up, Which is way out of my range for me being on a fixed income. Not sure which way to go. So I was thinking I know this is Heresy to say but has anyone tried installing another type of compressor in the machine using the same Condenser and Evaporator and controls or with some modifications at leas to get it to work again. The way it is now it's scrap to me. Since the old compressor is out I could fit a new type but smaller one in it. I know it won't be original but at least it would still look like a Monitor top and I could still use the frig. A matter of fact I still have another one with a burnt out motor sitting next to it. Both cabinet are in great shape as are the tops with no rust and original paint, door pedal opener, and racks for both. Both have been rewired including the light switch.
I seen a video where another person rewound the coil (stator) on one but just not sure if I have the skill or patients to do it or even know where to start or how, it would be a all new experience for me. Thoughts or suggestions on this. Jack.

Thoughts or suggestions on this. Jack. Jack, people are charging by the hour to deconstruct, reverse engineer, and rewind these stators. I paid what I considered a ridiculous amount for the last rewind I had done and it was approximately half of what you were quoted. The problem with modern compressors using the original condenser and evaporator are many. The first issue is the pressure rating of the low-side on the CA machines. The evaporator has a 30 PSI test pressure. Pretty well any refrigerant aside from methyl formate or other vacuum refrigerants will exceed this by a massive margin during standby conditions. If that isn't a problem (such as with CK evaporators) the new compressor will become a problem. The design of the Monitor Top requires a very large refrigerant volume. Modern compressors aren't engineered for this and will fail due to oil dilution or oil washout into the system. You might get around this by installing some older compressor design with a large oil volume; such as a 50's Tecumseh; but I don't know if that would fit inside the casing. On the Facebook group, someone mentioned mounting a modern compressor on a plate inside the dome, and another person spoke up about how they had done several and all had failed. As far as rewinding; Gill (Coldspaces) has done one or more and shared his experience in videos! There was a time when I was planning to go that route, but work has been too busy to devote that time. I sent the last one I did to a local shop for rewinding. It came back looking better than factory. I was shocked by the cost, but in the end my time is money and I couldn't acquire the tools and learn this skill for less time than the money was worth to pay them to just rewind it. I had one CA machine recently which ran but the unloader was stuck and would not "load" the compressor and start pumping. I cut that one out and repaired the unloader, then installed it into a different casing for a "historically significant" CA needing to be placed back in service. I don't have any other CA machines that aren't already burned, unfortunately. Sincerely, Daavid

I could live with $5-600 but would have to think hard about it. Could I get the name of the place you sent yours to? I still think I might try my hand at rewiring one. After all, I am retired and in no real hurry, and always like to try something new. Thanks.
Jack.

Not ready to share openly yet since there were some minor issues.

Hi Jack, I am willing to rewind the motor for you. P.M. me if you are interested. Would you be willing to share pictures of the motor here on the forum? Thanks, Mark

Thanks, Mark It's excellent that you are able to provide this service! I also would like to see the condition of his winding; but our forum is out of space for attachments. We are in talks about this, but as of now we can't attach pictures. This forum site is very poor on the administrative side. Only the initial creator of the forum can add credit for storage space. Normal admins such as myself cannot solve this problem.
