Sears Galaxy 721-8002401 problem. Wife opened microwave and saw spark near hole where door latches (bottom hole) just below monitor switch. Light went out inside microwave and the turntable wont rotate. I replaced inside light without success thinking turntable power might somehow run thru that circuit. Looking at schematics (conventiently stowed inside control panel) it seems that these two items do run off same circuit. Could it be relay #1 on control unit or is it possibly the monitor switch that they both run thru? Any help is greatly appreciated. You guys seem to be real microwave gurus. Thanks, Joe.

What's happening is you are activating one door switch a little before the other, and that is causing your light, fan, and turntable to come on. The plastic parts are not perfectly rigid, so they flex a little when you press the button, and that causes the lag to be more apparent. Even if you press the door open faster and look really close, you may notice the light, fan, and turntable coming on for a split second. That's perfectly normal. The relay on the control board must also be turned on before it will actually be cooking.

This is usually caused by either a bad door switch, a loose door switch mount.
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.

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. Other times, 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 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.
We have critical safety & disassembly info (including a how-to video) at our site, linked here.
If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

SOURCE: Broken latch microwave door - won't open
I have a semmins microwave working in great condition, last night the latch mechanism inside the microwave don't allow the door latch to close.Only the top portion, bottom portion is ok.
We replaced the board behind the control panel. $130.00. If you do this make sure you can put the wires back the right way. My husband finally got it and our micro is working like brand newThanks to all who tried to help.
