Error Code: OP Difficulty: Moderate
Problem: Open Sensor (e.g., Temperature Sensor)
How to Fix OP Error (Step-by-Step)
- Unplug the refrigerator from the wall outlet to ensure your safety.
- Locate the faulty temperature sensor. It is typically inside the fresh food compartment, behind a small plastic cover along the top or back wall.
- Remove any shelves that are in the way. Use a small flathead screwdriver to gently pry off the plastic sensor cover.
- Disconnect the sensor by pressing the locking tab on the wire harness connector and pulling it apart.
- Connect the new temperature sensor (Part #240597203) to the wire harness. You should hear a click as it locks into place.
- Snap the plastic cover back over the new sensor and reinstall any shelves you removed.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
