Possible Causes

Faulty refrigerator thermistor, Thermistor not properly attached to liner, Control PCB calibration fault, Air damper stuck open

How to Fix / Troubleshooting

Safety: Disconnect power before accessing sensors or control boards.

  • Step 1 – Verify settings: Ensure the temperature setting is not at the coldest level. Adjust to a warmer setting and monitor for 24 hours.
  • Step 2 – Check sensor placement: Locate the refrigerator thermistor and confirm it is clipped correctly to the wall or bracket, not hanging loose in cold air streams.
  • Step 3 – Inspect damper: If the damper is stuck open, excessive cold air from the freezer will overcool the fridge. Replace the damper if it does not respond to control changes.
  • Step 4 – Replace thermistor: If temperature readings on the display do not match an actual thermometer, replace the refrigerator thermistor.
