Possible Causes
Burned-out LED or bulb, Faulty door switch, Loose light wiring connector, Failed light driver on control board
How to Fix / Troubleshooting
Safety: Unplug the unit before replacing bulbs or accessing wiring.
- Check door switch: Press the door switch manually and see if the light flickers or comes on. If not, test the switch for continuity and replace if faulty.
- Inspect the light assembly: Remove the light cover inside the cabinet. Check for a burned-out bulb (if incandescent) or damaged LED module.
- Replace the bulb or LED: Install an OEM Avanti light bulb or LED module with the correct voltage and base type.
- Check wiring: Ensure the light wiring harness is securely connected to the control board or power source.
- Control board driver: If the switch and light module are good but the light never receives power, the light driver circuit on the control board may have failed. Replace the main control board if necessary.
