Possible Causes
Stuck or broken air damper, Frost buildup blocking air channels, Failed refrigerator fan motor, Mispositioned shelves blocking vents
How to Fix / Troubleshooting
Safety: Unplug the refrigerator before removing interior panels.
- Step 1 – Check air vents: Ensure that food items are not blocking the vents at the back or sides of the refrigerator compartment.
- Step 2 – Listen for fan: With the door switch pressed, listen for the evaporator fan running. If silent, the fan motor may be faulty.
- Step 3 – Inspect damper: Locate the air damper (often at the top or side of the fresh food compartment). Check if it opens and closes when temperature is adjusted. A stuck closed damper will keep the fridge warm.
- Step 4 – Defrost blockage: If you suspect ice blocking air passages, power off the unit and leave doors open for several hours to fully defrost, then restart.
- Step 5 – Replace parts: Replace a defective damper assembly or evaporator fan motor with Panasonic-specific parts if they do not operate correctly.
