Microwave over-the-range cooktop light does not work or flickers.

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

Steps:

• 1. Access bulb: Remove the lamp cover under the microwave to access the cooktop bulb.
• 2. Replace bulb: Install a new bulb of the correct type and wattage specified by MasterChef.
• 3. Check socket: Ensure the bulb is firmly seated and the socket is not burned or loose.

Note: If a new bulb flickers or does not light, the light relay or control board may be faulty.
