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

Safety: Unplug the microwave before accessing the lamp compartment.

Steps:

• 1. Confirm function: If heating and turntable work normally, the issue is likely limited to the lamp.
• 2. Access lamp: On many Tower microwaves, the cavity lamp is accessible from the rear or side via a small cover. Remove the cover screws.
• 3. Replace bulb: Replace the lamp with the exact type and wattage specified for your Tower model (often a special microwave-rated bulb).
• 4. Check connections: Ensure the lamp holder contacts are clean and the wires are firmly attached.

Note: Do not substitute with non-microwave-rated bulbs, as they may overheat or fail prematurely.
