How to Fix / Troubleshooting
Safety: Disconnect power before removing any panels.
- Power reset: Unplug the microwave for 10 minutes to reset the control logic.
- Harness reseat: Access the control area and reseat the ribbon cable and harnesses between the UI and main control.
- Check for interference: Ensure no wires are pinched between the cabinet and control panel, which can cause intermittent shorts.
