Possible Causes
Thermistor located too close to the evaporator, Control algorithm issue, Poor airflow, causing rapid local temperature swings
How to Fix / Troubleshooting
Unplug the unit before moving the sensor.
- Check ambient conditions: Ensure the cooler is not placed in a location with rapid temperature swings (e.g., direct sun, near HVAC vents).
- Inspect sensor placement: Access the interior panel and verify the thermistor is mounted where specified by hOmeLabs (usually mid-evaporator or wall), ensuring it is not touching only extremely cold spots.
- Improve airflow: Avoid blocking the vents and overloading the shelves. Good airflow reduces rapid temperature changes at the sensor.
- Replace sensor or board: If short cycling persists, replace the cabinet thermistor. If still unresolved, the main control board's control logic might be faulty and should be replaced.
