is usually caused by either a bad door switch, a loose door switch
mount (which are pretty simple problems to fix) or occasionally a
problem on the control panel.
Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.
Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.
There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.
The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.
Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.
One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.
If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.
You can usually find exploded views and order parts by entering your model number here at the Sears parts site.
If you only need a switch, you can order part # QSW-MA085WRE0 from Tritronics.
If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

one of 3 things, for sure the internal fuse is gone, then check for a: bad Hi-Voltage;diode, Hi-Voltage capacitor, or the magnetron tube is defective,none are too hard to change out,but the magnetron is fairly expensive to replace:
