E6 displayed; compressor may not start or may start briefly then shut off.

Safety: Unplug the ice maker before accessing the compressor compartment. Capacitors can hold a charge; discharge safely.

• Check ventilation: Ensure the unit has proper clearance around the condenser grille and that dust is not blocking airflow. Clean the condenser coil with a soft brush and vacuum.
• Inspect start components: Remove the rear lower panel to access the compressor. Carefully remove the start relay and start capacitor from the compressor terminals.
• Test relay: Shake the relay gently; if it rattles or shows burn marks, replace it. Use a multimeter to check continuity according to the relay type.
• Test capacitor: Use a capacitance meter to verify the capacitor value matches the rating on its label. Replace if more than ±10% out of spec or if bulged or leaking.
• Check compressor windings: Measure resistance between the compressor terminals (C, S, R). Extremely high or zero readings may indicate a failed compressor, which typically requires professional replacement.
• Reassemble and test: Install new start components if needed, restore power, and monitor compressor start-up.
