E10 displayed; unit may start but quickly aborts the cycle; fan may run but compressor does not.

Safety: Unplug the ice maker and allow the compressor to cool before touching. Only attempt electrical tests if you are comfortable working with mains voltage.

Steps:

• Listen for compressor behavior: When starting a cycle, you may hear a click and brief hum followed by a stop. This often indicates a start failure.
• Access compressor terminals: Remove the rear panel and the plastic cover on the compressor. Inspect the PTC start relay and overload protector for burn marks or loose fit.
• Check wiring: Ensure all wires to the compressor and relay are firmly connected and not charred.
• Replace PTC/overload: If the relay rattles when shaken or shows signs of overheating, replace the compressor PTC starter and overload protector as a set.
• Measure compressor windings (advanced): With power disconnected and wires removed from the compressor, measure resistance between the three terminals. Values should be finite and consistent with a small hermetic compressor. An open or shorted winding indicates a failed compressor.
• Control board relay: If the compressor never receives power (no voltage at terminals when commanded on), the main control board relay may be defective and require replacement.
• Professional repair: If the compressor windings are faulty, the compressor must be replaced by a refrigeration technician; this is not a typical DIY repair.
