Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the microwave before accessing the lamp area. The lamp may be behind a cover inside the cavity or behind the control panel, depending on the Paderno model.
Step-by-step checks:
- 1. Check door operation: Open and close the door and listen for distinct clicks from the door switches. If the light does not respond, a switch or lamp may be faulty.
- 2. Access lamp: Remove the lamp cover (inside) or control panel (front) to reach the lamp assembly.
- 3. Inspect lamp: Look for a broken filament or darkened glass. Replace with the exact type and wattage specified by Paderno.
- 4. Check socket and wiring: Ensure the lamp socket is not burned or loose and that wires are firmly connected.
- 5. Test door switch: With the cabinet removed and using a multimeter, test the secondary door switch for proper continuity when the door is closed.
