E5 error, unit powers on but compressor does not run, no ice production

Safety warning: Unplug the ice maker before removing panels. The compressor circuit carries mains voltage. If you are not experienced with electrical testing, contact a professional.

Steps to investigate E5:

• Ventilation check: Ensure the rear and sides of the ice maker have at least 10–15 cm clearance for airflow. Overheating can trip the compressor protection and trigger E5.
• Power reset: Unplug the unit for 20–30 minutes to allow the compressor overload protector to cool and reset. Plug back in and listen for the compressor attempting to start.
• Access compressor compartment: Remove the rear lower panel to expose the compressor, start relay/PTC, and overload protector.
• Inspect start components: Remove the plastic cover on the compressor terminals. Check the PTC start relay and overload protector for signs of burning, cracking, or melting. Replace if damaged.
• Test compressor (advanced): With the unit unplugged, disconnect the start components and measure resistance between compressor terminals (C-R, C-S, R-S). Infinite resistance or a short to ground indicates a failed compressor.
• Replace parts: If the PTC relay or overload is faulty, replace the compressor start relay/overload assembly. If the compressor itself is defective, the repair is complex and usually not economical for countertop ice makers.

Important: Refrigerant system repairs must be performed by a certified refrigeration technician.
