Possible Causes

Thermistor located too close to 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 (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), not touching extremely cold spots only.
  • Improve airflow: Avoid blocking vents and overloading 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 may be faulty and should be replaced.
