Microwave interior light does not come on when the door is opened or during cooking, but the unit heats normally.

Safety first: Unplug the microwave before replacing the lamp. Glass can be hot and fragile.

• Access lamp: On many Fisher & Paykel models, the lamp is accessible by removing the top grille and a small lamp cover, or from the rear.
• Inspect and replace bulb: Remove the old bulb and inspect the filament. Replace with the exact type and wattage specified by Fisher & Paykel.
• Check socket and wiring: Ensure the socket is not burned or loose. Tighten connections as needed.
• Test operation: Reassemble and test. If the new bulb does not light, the control board lamp circuit may be faulty and require professional diagnosis.
