Kenmore ice maker displays E9 and shuts down; unit may attempt to start then quickly stop.

Safety First: Unplug the ice maker before accessing the compressor compartment. Capacitors can hold a charge—discharge safely if present.

• Access compressor components: Remove the rear lower panel to expose the compressor, start relay, and overload protector.
• Inspect for overheating: Check if the compressor shell is extremely hot. If so, allow it to cool before further testing.
• Test start relay and overload: Disconnect the relay/overload assembly from the compressor terminals. Use a multimeter to check for continuity through the overload and proper resistance across the relay. Replace the assembly if open or rattling.
• Check supply voltage: With the unit plugged in (exercise caution), verify that proper voltage is present at the compressor terminals when it should be running. Low voltage can trigger E9.
• Compressor evaluation: If the relay and overload are good but the compressor hums and trips, the compressor may be locked and require professional replacement.
