Microwave interior light does not come on when the door opens or during cooking, but the unit otherwise works.

Safety first: Unplug the microwave before replacing the lamp. Avoid touching high-voltage components.

Step-by-step checks:

• 1. Access lamp: On many Midea models, the lamp is accessible from the back or top by removing a small cover. On others, you may need to remove the outer cabinet.
• 2. Inspect bulb: Check if the filament is broken or the bulb is darkened. Replace with the correct wattage and type specified by Midea.
• 3. Check socket and wiring: Ensure the lamp is seated firmly and that wires are secure.
• 4. If new lamp does not work: The lamp relay or control board may be faulty and require professional service.
