Display shows H2; ice maker or freezer temperature is too high, ice production is poor or stopped.

Safety first: Disconnect power before removing freezer panels or ice maker components.

Steps to address H2:

• 1. Inspect door seal: Check the freezer gasket for tears, gaps, or debris. Clean with warm soapy water and ensure it makes full contact with the cabinet.
• 2. Check for obstructions: Make sure food items are not preventing the door from closing or blocking the air vents.
• 3. Verify evaporator fan operation: With the freezer door open, press the door switch and listen for the fan. If silent, test and replace the evaporator fan motor if needed.
• 4. Look for frost buildup: Remove the rear freezer panel and inspect the evaporator. Heavy frost indicates a defrost issue; troubleshoot the defrost system.
• 5. Test freezer thermistor: Measure resistance and compare to the tech sheet. Replace if readings are incorrect.

If temperatures do not improve after these checks, a sealed system or control board issue may be present and should be evaluated by a professional.
