Sometimes, the freezer would get to the end of his freeze cycle, the thermostat would turn off, and then it would just not turn back on. I could tap the control box in the freezer and it would come back on and work for awhile, until the thermostat would stick again, which might take a day or a couple weeks. I suspected the thermostat. I ordered a new one. The directions were a little confusing, so I just ignored them and just replaced the thermostat, wiring it like the old one. Easy to replace. Working like a charm right now. The thermostat knob did not fit perfectly, but fit well enough to work and to stay. I am satisfied with it. Kenmore Coolspot upright Freezer 1068254982.
