I came to the conclusion that the motor had developed a problem, so I ordered a replacement, which was delivered to me the next day!! Thanks, Appliance Parts Pros, for such speedy delivery!!
The replacement procedure went fairly easily. I first removed the slide out tray from the ice/water well in the freezer door. Next, remove the 2 screws holding the bottom slide in place. From there, you can simply lift up and out on the trim piece, then remove the electrical connector from the back of the panel, and set the trim aside. The motor can then be changed by removing the 2 screws securing it to a bracket, routing the wire for removal, unplugging it from the control board, which is located behind a piece of cardstock and installing the replacement motor in the opposite manner as the removal of the old unit. Replace everything in the reverse order that it was disassembled, and you're back in business!
The only tools required were a phillips head screwdriver, and a 1/4" nutdriver.
A pretty straightforward repair!
