Possible Causes
Loose door wire harness connector, Damaged wire harness in refrigerator door hinge, Corroded connector pins, Main PCB communication fault
How to Fix / Troubleshooting
Safety first: Unplug the refrigerator before inspecting door harness connections.
Steps:
- Inspect top hinge area: On many Samsung French door models, the wire harness for the ice maker and dispenser runs through the top hinge. Remove the hinge cover and inspect the connector.
- Reseat connector: Disconnect and reconnect the harness connector to ensure a solid connection. Look for bent pins or corrosion.
- Check for pinched wires: Inspect the harness where it passes through the hinge area for cuts, pinches, or broken wires. If damaged, the door harness must be replaced.
- Power reset: After reseating connectors, restore power and check if PC ER clears. If not, further diagnosis of the main PCB may be required.
