Possible Causes
Thermistor reading slightly warm, Control board not recognizing setpoint reached, Poor insulation or door seal, Ambient temperature too high
How to Fix / Troubleshooting
Safety: Unplug before testing sensors or the control board.
- Check ambient conditions: Ensure the cooler is not installed in a very hot room or near heat sources, which can cause long run times.
- Inspect door seal and insulation: Verify the gasket seals well and that the door is not warped.
- Test thermistor: Measure the cabinet sensor resistance and compare to actual interior temperature. Replace if readings are inaccurate.
- Control board: If the sensor is accurate but the compressor never cycles off, the control board may be faulty and should be replaced.
