Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the refrigerator before removing switch assemblies or hinge covers.
Steps to resolve:
- Test switch operation: Open and close the door while watching the interior light. If the light stays on or off incorrectly, the switch may be faulty.
- Manually press switch: Press the switch plunger with your finger. If the light flickers or does not respond, the switch is suspect.
- Inspect hinge wiring: Remove the top hinge cover and check for pinched or broken wires leading to the switch.
If E18 remains after replacing a faulty switch or repairing wiring, the main control board input circuit may be damaged and should be evaluated by a technician.
