Possible Causes
Aging VFD (vacuum fluorescent display), Failing display driver on control board, Loose display connector, Low voltage from control board power supply
How to Fix / Troubleshooting
Safety first: Unplug the microwave.
- Check brightness settings: Some Ambiano models allow dimming the display. Verify it is not set to a low brightness mode.
- Inspect control panel: Remove the control panel and check the display connector for looseness or corrosion. Reseat the connector.
- Look for heat damage: Inspect the display area on the control board for discoloration or burnt components.
- Replace control board: If the display remains dim or segments are missing, the display or its driver is failing. Replace the main control PCB or display module as a unit.
