Possible Causes
Loose harness connection to ice/dispenser module, Broken wires in door hinge area, Faulty ice/dispenser control board, Main PCB communication port failure
How to Fix / Troubleshooting
Safety: Disconnect power before removing door covers or hinge trims.
- 1. Inspect door harness: At the top or bottom hinge (depending on model), locate the wiring harness that feeds the ice/dispenser module. Check for pinched, cut, or broken wires.
- 2. Reseat connectors: Disconnect and reconnect the harness connectors at the hinge and at the ice/dispenser module behind the door panel or display.
- 3. Check for moisture damage: Look for signs of water ingress around the dispenser area that may have affected the small control board.
- 4. Test operation: Restore power and see if EA clears. If it returns, the module or main PCB may be faulty.
- 5. Replace defective board: If wiring is intact, replace the ice/dispenser control module first. If EA persists, the main PCB may require replacement.
Recommendation: Door disassembly can be complex; consider a technician if unsure.
