Microwave interior light does not work, but the unit heats and operates normally.

Safety: Unplug the microwave before any lamp replacement. Lamps are often located behind panels that may expose high-voltage areas.

• Consult manual: Some Princess models allow user-replacement of the lamp via an access panel; others require full disassembly.
• Access panel: If your model has a dedicated lamp cover, remove it and replace the lamp with the exact type and rating specified.
• If no user access: Have a technician replace the lamp to avoid exposure to high-voltage components.
