How to Fix / Troubleshooting
Safety first: Unplug the unit.
- Check outlet: Test the outlet with another appliance. Avoid multi-plug adapters and long extension cords.
- Inspect power cord: Look for cuts, kinks, or burn marks on the Panasonic power cord. Do not use if damaged.
- Try another outlet: Plug directly into a different wall outlet on a separate circuit.
- Service if unresolved: If F03 persists, the internal power supply section of the control PCB may be defective.
Warning: Do not attempt to repair the power supply PCB unless you are qualified; capacitors can retain dangerous charge.
