Possible Causes
Loose ice maker harness connection, Damaged wiring between ice maker and main PCB, Faulty ice maker control board, Main control board communication failure
How to Fix / Troubleshooting
Safety first: Unplug the refrigerator before accessing control boards or wiring.
Steps:
- Check ice maker harness: Remove the ice bucket and ice room cover. Inspect the harness from the ice maker to the cabinet. Ensure connectors are fully seated and not pinched or damaged.
- Inspect cabinet connector: On many Samsung models, the ice maker harness plugs into a connector in the refrigerator wall. Check for corrosion or loose fit. Clean gently and reconnect.
- Power reset: Leave the refrigerator unplugged for at least 5 minutes to reset the control electronics. Restore power and run the ice maker test cycle.
- Board inspection (advanced): If the error returns, the ice maker control board (integrated into the ice maker) or the main PCB may be faulty. Visual inspection for burnt components or damaged traces can help, but typically the ice maker assembly is replaced first.
If replacing the ice maker does not clear 15E, a professional should evaluate and possibly replace the main PCB.
