Cooler set in direct sunlight or to close to heat source.
Check cold thermostat setting. Turn cold control screw. Turn clockwise for colder
water.
Defective cold control or compressor low on refrigerant.
Water dispensing from hot side not hot
Verify switch on rear of cooler is in the “On” position. Switch will light up when hot
