As far as the shipping is concerned. It took forever, just to find out that the part was incorrect.
Better luck next time. right?

Took microwave off the mount, removed all the outer covers except the face, used metal screwdriver to short the big capacitor to keep from being shocked, removed magnetron and replaced with new part. Put back together, hung on wall, and finished. I used a youtube video and it turned into a very simple fix.

After removing the over-the-range unit (no small feat!) I had to figure out how to open the case (good puzzle!).

Snapped off the top control panel which exposed the wiring connecting the control panel.
Unplugged a couple of wire harness units to free the control panel.
Be sure to label the units to know which goes where during reassembly.
Remove the microwave unit from the housing and place it on its side.
Remove the metal plate that houses the motor. 4 screws hold the motor in place. Disconnect the 2 wires from the old motor and you are ready to install the new motor. Be sure to TURN OFF THE POWER to the unit at the breaker box and remove the turntable from inside the microwave.
