How do I Replace the Light in a GE Profile Advantium 120?

Unplug the microwave from the wall outlet, or turn off the breaker.

Remove the screw from the right side of the light compartment, located on the underside of the microwave oven, then lower the cover.

Pull the bulb out of the light socket gently, then push the new bulb into the socket.

Raise the light cover back to its original position, then re-secure it using the screw that was originally removed.

Re-connect power to the microwave to complete the installation of the new light bulb.
