How to Fix E1 Error (Step-by-Step)

  1. Unplug the refrigerator from the power outlet for safety and confirm the error stays cleared during a full test cycle.
  2. Empty the fresh food section to get clear access to the interior walls and ceiling.
  3. 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.
  4. Use a small flathead screwdriver to gently pry the cover off, exposing the sensor probe.
  5. Disconnect the wire harness attached to the old thermistor. It will have a small clip you need to press.
  6. Connect the new thermistor to the wire harness until it clicks into place.
  7. Snap the plastic cover back on, return food to the refrigerator, and plug the unit back in.
  8. Turn the appliance off, wait about 2 minutes, then turn it back on.
