How to Fix / Troubleshooting

Safety: This symptom is usually not dangerous but can indicate a cooling control issue.

1. Observe duration: Many Panasonic ovens keep the cooling fan running until internal temperatures drop. Up to 30–40 minutes can be normal after high-temperature use.
2. Check for excessive heat: If the control panel or surrounding cabinetry feels very hot, the cooling system may be compensating for poor insulation or blocked vents.
3. Inspect vents and fan: Ensure vents are clear and the fan is not partially obstructed, which can reduce cooling efficiency.
4. Thermostat check: Some models use a mechanical thermostat to control fan off-time. If it never opens (fan never stops), the thermostat may be stuck and require replacement.
5. Control board: If the fan runs indefinitely even when the oven is cold, the control PCB may be faulty and holding the fan relay on.

Oven fan continues to run for an unusually long time after the oven is turned off.
