Error Code: F01 Difficulty: Hard
Problem: Temperature sensor failure.
How to Fix F01 Error (Step-by-Step)
- Unplug the refrigerator from the wall outlet to ensure your safety.
- Empty the refrigerator and freezer compartments, removing all food, shelves, and drawers to get clear access to the interior panels.
- Locate the temperature sensor. It is typically found in the fresh food compartment, behind a small plastic cover on the back or side wall, near the air vents.
- Carefully pry off the sensor’s cover with a small flathead screwdriver. Disconnect the sensor by gently unplugging its wire harness connector.
- Plug the new temperature sensor into the wire harness connector and snap it into place where the old sensor was mounted.
- Reinstall the plastic cover, all shelves, and drawers and confirm the error stays cleared during a full test cycle.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
