How to Fix / Troubleshooting
Safety: Use caution when working near live controls; unplug if removing covers.
- Check set temperature: Verify the setpoint on the control panel. Adjust to a higher (warmer) temperature and wait several hours to see if the unit stabilizes.
- Sensor check: If the display temperature seems inaccurate, inspect the cabinet temperature sensor for proper placement and damage. A sensor reading too warm can cause overcooling.
- Power reset: Unplug the cooler for 5 minutes, then plug back in to reset the control board.
- Observe compressor cycling: If the compressor runs continuously even when the set temperature is reached, the main control board relay may be stuck closed and should be replaced.
- Replace faulty sensor or board: If sensor tests bad, replace it. If sensor is good and compressor never cycles off, replace the main control board.
