Display shows E5 and the unit stops making ice; compressor may not start.

Safety first: Unplug the ice maker. Do not attempt to open the sealed refrigeration system or handle refrigerant without proper certification.

• Check ventilation: Ensure there is at least several inches of clearance around the sides and back of the unit. Overheating can trigger protection faults.
• Clean condenser area: If accessible, vacuum dust from the condenser coil and fan area at the back or bottom of the unit.
• Listen for compressor attempts: Plug in and start the unit. If you hear a click and brief hum followed by another click, the start relay or compressor may be failing.
• Access the compressor start components: With power unplugged, remove the rear panel. Locate the compressor and the small plastic start device and overload mounted on its terminals.
• Inspect for burn marks: If the start relay or overload looks burnt or smells burnt, replace the start device kit.
• Test continuity: Use a multimeter to check the overload and relay for continuity per their specifications. Replace if open or out of spec.
• If E5 persists after replacing start components: The compressor itself or the control board relay may be defective. This typically requires a professional technician and may not be economical to repair.
