How to Fix / Troubleshooting
Safety first: Unplug the unit before accessing the lamp area.
- Check door position: Some models only light when the door is open or during active cooking. Verify correct operation mode.
- Inspect lamp: Access the lamp cover inside the cavity. Look for a visibly burned bulb or damaged LED module.
- Replace lamp: Replace the bulb or LED module with the correct Chefman-specified part.
- Wiring and driver: If a new lamp does not work, check wiring continuity and the lamp driver circuit on the control board. Replace the control PCB if the driver is faulty.
