How to Fix / Troubleshooting
Safety First: Unplug the microwave and allow it to cool before servicing.
- Verify mode: Ensure you are selecting the correct convection or grill mode and temperature per the user manual.
- Check fan operation: In convection mode, the convection fan should run. If it does not, test and replace the convection fan motor if necessary.
- Test elements: With power off, access the convection heater and grill element and test for continuity. An open element must be replaced.
- Control board: If elements and fan are good, the heater relay on the control board may be defective and require replacement.
