Microwave interior light does not come on, but unit heats and runs normally.

Safety First: Unplug the microwave. The light area may be near high-voltage components.

Steps:

• Access bulb: On many Frigidaire models, the interior bulb is accessed by removing the top grille and a small cover, or from the rear.
• Replace bulb: Install the correct Frigidaire microwave cavity light bulb (matching wattage and base type).
• Check socket: Ensure the bulb is seated firmly and the socket is not burned.

Note: If a new bulb does not light, the control board light relay or wiring may be faulty and require professional service.
