How to Fix / Troubleshooting
Safety first: Disconnect power at the breaker. High voltages are present on the control board; if you are not experienced with electronics, contact a qualified technician.
- Access main control board: Remove the top or rear panel to expose the control board assembly.
- Visual inspection: Look for darkened areas, cracked solder joints, or melted relay cases. Any visible damage indicates the board should be replaced.
- Check for stuck heating: If the oven elements heat even when the oven is off, a relay may be welded closed. Do not continue using the oven in this condition.
- Board replacement: Label and disconnect all wiring from the control board. Remove mounting screws and install the new board, transferring any jumpers or configuration plugs as per the service manual.
- Test: Restore power and run a short bake cycle to confirm normal operation and that the F7 code is cleared.
