Possible Causes
Burned-out cavity bulb, Loose lamp socket, Failed lamp relay on control board
How to Fix / Troubleshooting
Safety first: Unplug the microwave.
Bulb replacement:
- Locate the lamp access cover (often behind the control panel or on the rear of the unit).
- Remove the cover and carefully unscrew or pull out the old bulb.
- Install a new bulb of the correct type and wattage specified by Emerson.
If a new bulb does not light, the socket or control board lamp circuit may be faulty and require technician service.
