Removing a GE over-the-range microwave can be an easy task if it is approached with the right knowledge and tools. Microwave ovens can be heavy and unwieldy, and the process will require that the microwave be lifted and carried. At least two people are required, and having a third person is helpful.
Removing the Microwave
Pull the electrical cord from the socket. The socket should be just above the microwave, inside the cabinet.
Look for the vent duct that comes out the top of the microwave. This ductwork is usually held together with Phillips screws and is sealed using duct tape. Cut a line in the tape using a razor knife, and then peel the tape away from the ductwork. Remove the Phillips screws. Pull the ductwork up and away from the top of the microwave.
Remove the two or three Phillips bolts that hold the microwave into the cabinet. These bolts are long, and using an electric screwdriver or a drill will make the process much easier. A second person should be holding the microwave at this point, putting pressure up and toward the rear wall. If the microwave is not held firmly, it can fall away from the wall.
The end of the electrical cord will fit through a notch that is cut in the cabinet. A third person can make sure that the plug will go through the notch.
Grab the microwave from the bottom, one person on each side. Let the microwave tilt out slightly, and then lift up. Pull out, and the microwave will come loose from the wall bracket. Carry the microwave to a clear area and set it down.
Remove the three Phillips bolts that hold the wall bracket on. The bracket will be loose, but you may have to pry it away from the wall.
