I removed microwave from wall and started to disassemble. Located the two switches for the door. Had to remove quite a few parts to get to the door switches. Once I was able to get at the bracket I replaced both switches and reassembled the microwave and put it back on the wall bracket above our stove. Open the door and light comes on and works all the time. With the parts and shipping it only was $40.00. By replacing the parts I saved myself from purchasing a new microwave. Took me about 2 hours from start to finish.
