E5 displayed; unit may not start cooling or may shut down shortly after starting.

Safety first: Unplug the ice maker before cleaning or working near the compressor. Do not attempt sealed system repairs yourself.

Steps to troubleshoot E5:

• Check ventilation: Ensure the Silonn ice maker has at least 6 inches (15 cm) of clearance on all sides and is not placed in a confined cabinet. Move it to a cooler, well‑ventilated area.
• Clean condenser: Remove the rear or side panel to access the condenser coil. Use a soft brush or vacuum to remove dust and lint from the fins.
• Verify fan operation: With the panel off, plug in the unit and start a cycle. Confirm the condenser fan motor spins freely. If it does not run or is noisy, it may be failing.
• Check for overheating: Carefully feel near the compressor (do not touch bare terminals). If it is extremely hot and shuts off quickly, the overload protector may be tripping due to high load or a refrigerant issue.
• Basic reset: Unplug the unit for 30 minutes to allow the compressor to cool, then restart. If E5 returns, further diagnosis is needed.
• Do not open sealed system: Low refrigerant or a blocked capillary tube requires a certified refrigeration technician.

When to call a professional: If the fan is running and airflow is good but E5 persists, or if the compressor is very hot or clicking on and off, contact a professional for sealed system diagnosis.
