Door Switch went bad, Internal Fan would run every time you open the door
Unscrewed the control panel (2 screws), lift up and let hang, with a plan screwdriver open bracket holding the switch, unplug 2 wires, replace with new switch, plug in the 2 wires, push switch back into bracket. Then slide on the control panel, put the 2 screws back. Easy fix.
First I had to accept the fact that the unit was designed to keep non-professional people from doing any repairs. The switch was installed in such a manner that I had to break the mounting to remove the switch, then drill a hole in the mounting to secure the new switch in place.
Remove the top of the microwave, regular phillips screws on sides, torque screws on back. Lift up back and slide off cover. Light bulb socket is easily detached and bulb unplugged and replaced. Slide cover from back lifted slightly so lip will slide into front of microwave, than replace screws. Be sure to unplug microwave before you start.
I ordered a new one by calling the 800 number, gave them my model number and ordered a new one on the phone and paid with my credit card. It was shipped the same day and I received it on the second day by Fed-X.
