I replaced the temperature control in the freezer(freezer on bottom), it worked, then half hour later or so it stopped working. I played around with the temperature control a little more and the refrigerator began running again for another half hour or so. I replaced the defrost timer and the same thing is happening. I removed the temperature control, tested it and it seemed to be fine. I jiggled the wires on the temperature control, took off and put back on, and the refrigerator kicked back on. My question is what would cause the refrigerator to shut on and off, the compressor is turning on and cooling for one hour or so. What am I missing?
