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.
