H1 or HI temperature warning, ice compartment too warm

Safety: Unplug the unit before cleaning or accessing internal parts.

Steps to address H1:

• Check door/lid seal: Inspect the gasket for tears, warping, or debris. Clean the gasket with warm soapy water and ensure the door closes fully without obstruction.
• Verify ambient conditions: Ensure the unit is not installed in a very hot area and has proper ventilation clearance.
• Clean condenser: Remove the rear panel and clean the condenser coil with a brush and vacuum.
• Check condenser fan: Confirm the fan runs when the compressor is on. Replace the fan motor if it does not start or is noisy.
• Monitor temperature: Place a thermometer in the ice compartment and run the unit for several hours. If it does not reach the specified temperature, there may be a sealed system issue or sensor fault.
• Sensor check: Test the compartment temperature sensor as described for F1. Replace if readings are incorrect.
• Technician service: If airflow and sensors are good but cooling is still inadequate, a refrigerant leak or compressor problem is likely and requires professional repair.
