The microwave stopped working unles I moved the door up or down and held it but now it stopped altogether. So I replaced the middle door switch got nothing then I took the middle switch and tried it in place of the top switch still nothing, then I tried to replace the bottom switch with the middle switch and it started working when the door was open I closed the door immediatley. I would suspect that there is a problem with the bottom switch? Is there a differance between the middle switch and the bottom switch? Is this why the microwave started working with the door open because the bottom switch is opposite open vs closed. I hope I explained it well enough.
