Title: WD12 Compressor Post by: Marines27 on September 28, 2017, 01:58:06 pm Greetings,
I have WD12 with a type M thermostat. It has run without incident for 25 years. Recently, I noticed the beverages in the cooler were freezing as the compressor was not shutting off. I unplugged the cooler, let it sit for a few hours then a day, with the same problem. When I plugged it back in the last time, the compressor does not start. The evaporator fan runs so it is not a power supply nor a capacitor issue as I understand it. I ran a conductivity test from the terminal board to all three terminal posts on the compressor and that checked good. I manually adjusted the thermostat with no success. .
