In the unlikely event that this thing springs a leak while I'm not home, will it kill my small dogs? Thanks, Rob

Hi Rob ! No it shouldn't spring a leak unless it's mistreated (like defrosting with a sharp implement) never do . Have a ck b-16 in house now it works great would highly recommend one .

This has probably been covered, but does my flat top use sulfur dioxide as refrigerant? Thanks again! All CJ models listed use SO2. However, some of the CF-2's starting in 1939, and some CE models starting in 1938 had Freon-12 (R12). The piston stroke in the compressor was modified to suit. The only monitor tops to get R12 were a few CK-3 types from 1938-1941 which implies they were rebuilds only. Just for your confirmation, there should be a plate riveted somewhere like the side of the compressor specifying the compressor type, refrigerant type, and weight of refrigerant.

As far as when it leaks...it will drive anything, including a dog or cat, out of the room. Travis can confirm that even a curious cat who won't stay still will cough and hack and then come running back to fresh air. As long as your pets have a place to go in the very unlikely event of a leak they should be fine. These things don't just start leaking. You have to abuse them first. One thing to check is the pipe connections coming to and from the rear plate condenser. Make sure it isn't rusty and coat it with some rust conversion paint like I did on my flat top.

Hi Everyone,
Just wanted to stop by to tell everyone that my flat top is running just fine and has been for months! I love this thing so much that I went out and bought another one! I'm going to make another post about that in a minute. I wanted to take a second to give a big thank you to everyone who helped me get this one going!!
Rob

Hi everyone! Things have been going great for the last 2 years....up until the other night. I turned the refrigerator off to defrost it for a couple of hours. I cleaned the inside of the unit and dried everything off and plugged it back in. Everything seemed alright and the unit started cooling down. A few hours later, I went out to the garage to get a cold drink and when I grabbed the handle, I got shocked! When I rewired it a few years ago, I never hooked up the ground, so that was the first thing I did when I started troubleshooting. As soon as I plugged it up after attaching the ground to the frame by the motor, it tripped the GFCI immediately. Then, I disconnected the light and the thermostat and wired the hot side straight to the relay and still, when I plugged it up, the GFCI tripped.
Is it possible that the motor has shorted to the frame internally? Or is it more likely that the relay has died? I'd love some suggestions or some direction for troubleshooting.
Thanks everyone!!
Rob

I would suggest disconnecting all three wires from the motor (noting where they go of course!) and making sure the exposed ends can't touch anything. Then plug in. If the GFCI does not trip, it pretty much indicates the motor is the electrically leaky part. The kind of leakage that would cause tripping would, I expect, show up on a digital multimeter - so, if you have one measure the resistance from any of the terminals to an unpainted piece of metal connected to the compressor case, such as the copper tubing. Ideally, the resistance would be well up in the hundreds of K ohms or more. The higher the better.
If the motor is at fault, you can still use it safely with an isolating transformer - provided the windings haven't actually broken down to the casing in more than one place.

In this case, you need to think about "what changed" since it was running correctly. It seems that defrosting was the only thing done. That can introduce moisture into areas that don't normally see a lot of moisture. As cablehack said above, you can eliminate the compressor by disconnecting its wiring and taking resistance measurements to ground. You can go a step further by disconnecting the wiring at the relay so that all circuts are separate, and checking them all to ground. I would expect the thermostat or light circuit is still at fault somehow.

I guess my question is have you rewired it ? Because you have something going to ground, and if it’s not grounded it we’ll use you as a ground. Electricity always seeks easiest way to ground.
