Above the stove mounted microwave. I dropped the lens cover from under the bulb and tried to remove the bulb. The bulb separated from the base. I tried to remove the base with a pliers and the lamp socket broke. I ordered the parts and dropped the bottom cover of the unit down (5 screws). Removed 1 screww from the lamp socket, unplugged the wires and took it out. Simply replaced socket, fastened bottom cover of microwave, installed new bulb and closed lens cover.
At first I tried to use pliers to unscrew the base,very uncomfortable working position,upside down and backwards(the microwave is installed over the range top)very limited space for your body and arms to manuver and you really cant see the base,all of this took place after the breaker was turned off ofcourse,finally figured out that you can drop the entire bottom housing of the microwave by unscrewing 6 screws and the light sockets are easily accessable once you lower it,take out 1 retaining screw ,remove the entire socket and unscrewed the broken base and replaced the bulbs,I said bulbs,there is no sense in having to replace another bulb in who knows how long since only one had burned out but they were both the same age
Had to take unit off wall and disassemble the main casing.then disconnected the wires from the magnetron.took the mounting nuts off but wasn't able to remove the magnetron until I loosened the transformer out of the way .Then it came out easy.Installed the magnetron ,tightened the nuts,installed the transformer back in, connected the the wires back on and installed the casing on ,screwed the screws and got help to install the unit to the wall again.....Tested the unit before putting back on the wall to make sure it heated....The parts were exac same type and wasn't too hard to do...
