After re-wiring the unit and adding a ground wire (Mine was sitting on concrete and would have required a rubber pad to prevent from being shocked) the unit ran for about a year and stopped. It was pretty clear that when I tried to turn it back on the compressor was stuck and the unit would kick off after about 5 seconds on thermal overload. The starter relay checked out OK (Voltage was being sent to the compressor in both Run and Start). I checked the capacitor and it would not hold a charge so I replaced it with a SUPCO RO81 convinced this was the problem, but still no go. Deep in the GE CK repair manual it mentions that for 1 second you can apply 220 volts (any longer and the motor can be damaged). Using my 220 volt welding receptacle and my welding extension cord I connected the two (2) hot wires from the 220 volt to the 110 volt supply line into the refrigerator (Hot and Neutral or Red & Black) leaving the ground unconnected on both. Carefully I turned the unit on and on the 2nd 1 second try, the compressor was unfrozen. An excerpt from the GE CK Manual is attached. Free Beer!....tomorrow. Attachments:

That’s great. I’m glad the 220 trick worked for you!

A Supco RO81 is a start relay not a capacitor and the original relay wouldn't have held a charge?

Hey it's great that you got it going; however I have to ask one thing. Did you leave the RO81 in place? I ask because the CK30 and CK35 are designed as capacitor-start motors. The RO81 does not have a capacitor. If the original capacitor was failed, it is unlikely that an RO81 alone would reliably start the compressor with no capacitor or a failed capacitor in the circuit. Sincerely, David
