Freezer interior temperature fluctuates widely; items near the door thaw while items in back stay frozen.

Safety first: Avoid overloading shelves to the point of collapse.

Steps:

• Reorganize contents: Keep air gaps between items and avoid blocking vents.
• Verify fan operation: Ensure the evaporator fan motor runs when the compressor is on.
• Check sensor: Test and replace the cabinet thermistor if readings are unstable.
• Monitor with thermometer: Use a separate freezer thermometer to verify the actual temperature and adjust the setpoint accordingly.
