How to Fix / Troubleshooting
Safety: High surface temperatures can cause burns. Allow the oven to cool and disconnect power before inspection.
- 1. Check cooling fan operation: During a bake cycle, listen for the top/front cooling fan. If it does not run, the fan motor or its supply may be faulty.
- 2. Inspect vents: Ensure that the front and top ventilation slots are not blocked by cabinetry trim or debris.
- 3. Door glass inspection: Examine the inner and middle glass panes for cracks or gaps. If a pane is broken or missing, replace the door glass assembly.
- 4. Check door seal: A poor seal can allow hot air to escape onto the door. Replace the gasket if worn.
- 5. Replace cooling fan: If the tangential fan is not running and tests open-circuit, install a new Panasonic cooling fan motor.
