E5 appears and the unit stops; compressor may not start or may shut off quickly.

Safety first: Unplug the ice maker. Allow the compressor area to cool before touching. Do not bypass thermal protection devices.

Steps to address E5:

• Check ventilation: Ensure the ice maker has the clearance specified by NewAir (typically several inches on all sides). Move it away from walls or heat sources.
• Clean condenser coils: Remove the rear or bottom panel to access the condenser. Use a soft brush and vacuum to remove dust and lint from the coils and surrounding area.
• Inspect condenser fan: Verify the fan spins freely by hand. Look for debris blocking the blades. With power briefly applied, confirm the fan runs when the compressor is on. Replace the fan motor if it does not run.
• Check ambient temperature: Very hot rooms can cause overload. If possible, relocate the unit to a cooler area.
• Reset and test: After cleaning and ensuring airflow, let the unit sit unplugged for 30 minutes to allow the compressor overload to reset. Plug in and monitor operation.

Warning: If the compressor repeatedly overheats or hums and clicks without starting, it may be failing. Compressor replacement requires specialized tools and should be done by a refrigeration technician.
