Electrolux ice maker shows E04 and shuts down; unit may be unusually warm inside.

Safety First: Unplug the unit before cleaning coils or accessing the fan. Beware of sharp metal edges.

• Clean condenser coils: Pull the ice maker away from the wall. Use a coil brush and vacuum to remove dust and lint from the condenser coils. Ensure airflow around the unit is not blocked.
• Check condenser fan: With the rear panel removed, spin the condenser fan blade by hand; it should move freely. Restore power briefly and confirm the fan runs when the compressor is on. Replace the fan motor if it hums, stalls, or does not start.
• Verify installation environment: Ensure the ice maker is not installed in a confined cabinet without ventilation or near a heat source. Ambient temperature should be within Electrolux specifications.
• Inspect temperature sensor: Locate the high-temp sensor or cabinet thermistor. Check for loose connections or damaged wiring. Test resistance and compare to the service manual chart; replace if out of range.
• Reset and test: After correcting airflow and component issues, clear the error (power cycle or service mode reset) and monitor operation for several hours.
