How to Fix E3 Error (Step-by-Step)

  1. Unplug the refrigerator from the wall outlet to cut all power.
  2. Empty the freezer of all food, shelves, and the ice maker assembly to access the rear interior panel.
  3. Unscrew and remove the rear panel inside the freezer. This will expose the silver evaporator coils, which may be covered in frost.
  4. Locate the defrost bi-metal thermostat. It is a small, round component clipped directly onto the copper tubing of the evaporator coils.
  5. Disconnect the wires leading to the old thermostat. You may need to cut them and strip the ends if there is no plug.
  6. Using wire connectors, attach the new thermostat’s wires to the wires in the freezer. Ensure the connections are secure and waterproof.
  7. Firmly clip the new thermostat onto the evaporator tube, re-install the rear panel, and restore power.
  8. Turn the appliance off, wait about 2 minutes, then turn it back on.
