My husband and I went out of town and came back to a shattered glass on the microwave door, how frustrating, is this normal? I see the best thing for me to do is purchase a new door. Just thought that was Weird that only the glass was shattered and everything else was fine.

Ordered top & bottom micro-switches and mounting plate parts. Internet reviews could not find specifics if the issue was due to a top/bottom or combination of micro-switch or mounting plate failure.

... Read morehillip screw at the top vent assembly area. Lifted control panel upward to release the catch and moved it off to the side - didn't disconnect any leads. Used a Torx bit to remove the door switch mounting plates at the front and pulled the plates through the opening from the control panel. Documented the wire color code connections, the top plate uses 2 micro's with one using both the closed & open contact. Installed the respective micros on the mounting plates and worked backwards with the wiring and removal steps. Once completed, the open/close sensing has worked every time.
