Possible Causes
Faulty refrigerator NTC sensor reading too warm, Stuck relay on main PCB keeping compressor on, Incorrect temperature setting, Air damper stuck open
How to Fix / Troubleshooting
Safety: Unplug the unit before testing sensors or boards.
Steps to correct overcooling:
- Verify settings: Ensure the temperature is not set to the coldest level. Adjust to a mid-range setting and monitor.
- Check sensor: Test the refrigerator compartment NTC sensor for correct resistance. Replace if out of specification.
- Inspect air damper: Confirm the damper between freezer and fridge is not stuck fully open. Replace if it does not respond to control changes.
- Control board evaluation: If the compressor never cycles off despite correct sensor readings, the main PCB relay may be stuck and the board should be replaced.
Tip: Use a fridge thermometer to verify actual temperatures after adjustments.
