Synchronous Motor WB26X10143

I had previously determined the like culpit was the synchronous motor. The roller guide had flat spots on each roller. Order parts from Part Select - pretty good price, parts were delivered in 3 days - much faster than I expected. Printed out a parts diagram from their website and grabbed my screwdriver. Also needed a pair of side cutters to cut the metal web that held the motor cover in place - only need to unscrew screw that hold the cover in place (bottom), cut the metal connectors, remove the plate and unscrew the screw holding the motor in place, pull out old unit, replace with new motor and secure the motor with the screw. Put the cover in place and secure - put the microwave back on the counter, pluf it in, put something in the oven and start her up. Took less than 15 minutes and cost me $50 for the parts. Great deal and easy to do.

The turntable made a clicking noise, sometimes turned in the wrong direction, and wouldn't turn when there was any weight on the plate. Nothing appeared broken in the 3 spoked thing on whcih the plate sits. I replaced the motor, but this did not fix the problem; everything works fine until I put on the plate or any food on the plate. I now suspect that the wheels of the 3 spoked thing have worn down. They have flat spots on them. They don't turn when the motor turns, but drag. I suspect that this drag was what striped my first motor. I will next replace the 3-spoked thing.

Turntable in the microwave stopped turning.

Removed the back plate, removed the old motor and re-attached the new motor and the back plate. Took about 5 minutes. Works great.
Lesson learned - DON'T let your spagetti boil over.

Unscrewed the base plate (3 screws) on the bottom side of the microwave, unscrewed the motor (1 screw) replaced motor, reattached plate, plugged in power cord, works great! Took 3-5 minutes

Remove tray and rotating ring assembly. Turn the microwave onto the back. Locate the center plate and cut it loose with the side cutters. (Note: there are retaining slots on the opposite side) these slots hold the cover plate in place when reattaching. Use a magnetic phillips head screw driver so you don't drop the cover retaining screw. After cutting loose the cover, unplug the wires from the motor. (Note placement for correct reattachment). Remove 2 screws and remove old motor. Replace motor. Replace the screws and reattach the wires. Replace the cover (rotate so the prongs fit into the slots) tighten screw; you're done!!! I ordered the rotating ring, but I don't need it. Now I have an extra.
