Freezer cold but refrigerator compartment warm; ice buildup on back wall of freezer

Safety: Unplug the appliance before removing internal panels. Beware of sharp metal edges and ice.

Steps:

• 1. Check fan operation: With the unit running and the freezer door switch pressed, listen for the evaporator fan. If silent, see fan-related entries.
• 2. Inspect for frost: Remove freezer drawers and look at the rear panel. A thick, even layer of frost indicates defrost failure.
• 3. Manual defrost: Turn off and unplug the fridge. Leave doors open until all ice melts (towels to catch water). This will temporarily restore airflow.
• 4. Check air vents: Ensure vents between freezer and fridge are not blocked by food packages or ice.
• 5. Investigate defrost system: Test defrost heater, thermostat, and sensor as described in defrost error entries. Replace faulty components.
• 6. Door gaskets: Inspect gaskets for gaps or tears that allow moist air in. Replace damaged gaskets.

Tip: After repair, allow 24 hours for temperatures to stabilize.
