Possible Causes

Faulty thermostat contacts, Misreading thermistor, Control board logic fault, Sensor placement issue

How to Fix / Troubleshooting

Safety: Unplug the refrigerator before accessing controls or sensors.

  • 1. Verify sensor placement: Ensure thermistors are properly clipped in place and not hanging or touching very cold surfaces.
  • 2. Test thermostat (mechanical): Replace the temperature control thermostat if it causes rapid cycling or has pitted contacts.
  • 3. Replace faulty thermistors: If sensor readings are unstable or out of spec, install new thermistors.
  • 4. Control board: Persistent erratic cycling with good sensors and thermostat points to a failing main control board.
