⚠️ Safety Warning: Appliance repair involves electricity, gas, and moving parts. Always disconnect power before working on any appliance.
Error Code: E1 Difficulty: Moderate
Problem: Refrigerator thermistor (temperature sensor) is open.
How to Fix E1 Error (Step-by-Step)
- Unplug the refrigerator from the power outlet for safety and confirm the error stays cleared during a full test cycle.
- Empty the fresh food section to get clear access to the interior walls and ceiling.
- Locate the thermistor cover. It’s a small, vented plastic housing, usually on the upper right side wall or near the control housing at the top.
- Use a small flathead screwdriver to gently pry the cover off, exposing the sensor probe.
- Disconnect the wire harness attached to the old thermistor. It will have a small clip you need to press.
- Connect the new thermistor to the wire harness until it clicks into place.
- Snap the plastic cover back on, return food to the refrigerator, and plug the unit back in.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
