Possible Causes

How to Fix / Troubleshooting
Safety: Disconnect power before removing ice maker covers.
- Inspect ice maker housing: Ensure all covers and foam seals around the ice maker are intact and properly seated.
- Check ice maker fan: Some models use a dedicated fan to blow cold air into the ice maker compartment. Verify the fan runs when the freezer is cooling. Replace if it is noisy, seized, or not running with power applied.
- Limit door openings: Frequent or prolonged door openings can raise compartment temperature. Verify the door closes fully and is not obstructed.
- Sensor check: If accessible, test the ice maker compartment thermistor and replace if out of spec.
