Microwave cavity light flickers during operation, independent of door opening.

Safety: Unplug the microwave before accessing the lamp.

• Step 1 – Check lamp seating: Access the lamp and ensure it is firmly seated in the socket.
• Step 2 – Replace lamp: If flickering continues, replace the lamp with the correct type and wattage.
• Step 3 – Inspect wiring: Check the lamp wires and connectors for looseness or corrosion. Reseat as needed.
• Step 4 – Relay issue: If the lamp is good and wiring is secure, the lamp relay on the control PCB may have worn contacts and the board may need replacement.
