Freezer is cold but refrigerator section is warm; ice cream is hard but milk spoils quickly.

Safety first: Unplug the refrigerator before removing interior panels.

Steps to resolve:

• Check for blocked vents: In the refrigerator section, locate the cold air vents (usually on the back or top). Move food away to allow at least a few inches of clearance.
• Listen for fan: Open the freezer door and press the door switch. You should hear the evaporator fan running. If not, the fan or its circuit may be faulty.
• Inspect for frost: Look at the back panel of the freezer. A thick frost layer or snow-like buildup indicates a defrost problem. Unplug the unit and allow a full 24-hour defrost with doors open and towels in place.
• Check damper operation: In the fresh food section, locate the damper vent. With the unit running, feel for cold air. If none after defrosting, the damper may be stuck closed and require replacement.

If the problem returns quickly after manual defrost, the automatic defrost system (heater, thermostat, or control board) needs diagnosis by a technician.
