Microwave interior light does not turn on, but unit heats normally

Safety: Unplug the microwave before accessing the lamp. Some models require removing the outer cover; others have a dedicated lamp access panel.

• Access lamp: Refer to the user manual for lamp access location. Remove the cover or panel as instructed.
• Inspect bulb: Check if the filament is broken or the bulb is darkened. Replace with the same type and wattage specified by Haier.
• Check socket: Ensure the bulb is firmly seated and the socket is not burned or loose.
• Control issue: If a new bulb does not light, the control board lamp circuit may be faulty and require professional repair.
