Possible Causes
Faulty fresh food thermistor, Stuck relay on main control board, Damper stuck open, Incorrect temperature settings
How to Fix / Troubleshooting
Safety first: Unplug the refrigerator before accessing sensors or control boards.
- Verify settings: Ensure the fresh food temperature is set to around 37°F and not at the coldest setting.
- Check damper: Inspect the air damper to see if it is stuck open, allowing too much cold air from the freezer. Replace the damper assembly if it will not close.
- Test thermistor: A failed thermistor can report warm temperatures and keep the compressor running. Test and replace the fresh food thermistor if readings are incorrect.
- Control board: If the compressor runs continuously even when the interior is very cold and sensors are good, the main control board may have a stuck relay and should be replaced.
