Over-the-range microwave hood light under the unit does not work or flickers.

Safety: Turn off power at the breaker or unplug the microwave before changing bulbs.

• Replace bulb: Remove the lens cover under the microwave and replace the bulb with the correct type and wattage recommended by KitchenAid.
• Inspect socket: Look for discoloration or melting around the socket. Replace the socket if damaged.
• Check for flicker causes: If the light flickers, ensure the bulb is fully seated and the socket contacts are clean.
• Control issue: If the bulb and socket are good but the light will not turn on from the control panel, the main control board's light circuit may be defective and require replacement.
