[Corrective Action] Check the electrical receptacle for power and correct voltage. The incoming voltage must be within 10% of the rated voltage on the serial nameplate. The cold thermostat is usually located behind the front panel or apron assembly. If the cold thermostat capillary bulb loses it's charge or becomes kinked, it will fail in the open position, causing disruption of power to the compressor. Unplug the water cooler and, using an ohm meter, check the continuity across the two electrical terminals on the thermostat. Install a new thermostat if there is not continuity. Check for loose wires within the compressor box. The incoming power leads must be connected to the overload and relay. If all components check positive for continuity, test the wiring harness plug for continuity to see if there is a broken wire within the wiring harness insulation. [Problem]
