How to Fix / Troubleshooting
Safety first: Unplug the microwave before opening the control panel.
Steps:
- Power reset: Unplug for several minutes and reconnect to see if the display stabilizes.
- Check for moisture: If installed above a stove, allow the unit to dry out; steam can temporarily affect the display.
- Inspect connections (technician): Remove the control panel and check the display module connector to the control PCB. Reseat if loose.
- Replace control PCB or display: If the display remains dim or segments are missing, the control PCB or display itself may need replacement.
