How to Fix / Troubleshooting
Safety first: Disconnect power before attempting to access the lamp.
Basic checks:
- Consult your Wolf microwave manual to locate the lamp access panel (often behind a grille or panel).
- If accessible to the user, remove the cover and visually inspect the bulb for a broken filament or darkened glass.
- Replace the lamp only with the Wolf-specified type and wattage.
If the lamp is not user-accessible or E17 persists after lamp replacement:
- The lamp socket, wiring, or control relay may be defective.
- Contact a Wolf technician to test the lamp circuit and replace the faulty component.
