If the microwave is blowing fuses or the breaker while opening the door, chances are really good it’s the monitor switch. Which is the middle or second switch. If you remove the plastic “latch board,” the receptacle the door hooks latch into which holds the switches, be certain to reinstall correctly. Because there’s a small plastic hook that must go through the metal structure before the board is slid downward into position. It’s possible to install this without properly seating it, without sliding it downward into position, but if you the switches will not align properly with the door hooks and it’ll just blow the fuse or breaker again. Also when ordering the monitor switch make sure you order the right one. Because the upper switch has the same KW3 number on it but they’re not the same switch. And they cannot be substituted because the upper is normally open and the monitor switch is normally closed. Lastly, do not open the microwave door while it’s running. Because it arcs the monitor switch internally every time and shortens its life. Let it finish running or hit cancel.
