Possible Causes
Aging VFD display, a failing display driver on the control board, a loose display ribbon cable, or a low-voltage power supply issue on the control board.
How to Fix / Troubleshooting
Safety: Unplug the microwave before accessing the control panel.
- Power Reset: Disconnect power for 5 minutes and then restore it to see if the display recovers.
- Inspect Connections: Remove the control panel and reseat the ribbon cable between the display module and the main control.
- Check for Heat Damage: Look for discoloration or burnt components near the display driver circuitry.
