My 8 year old daughter cleaned the inside of the microwave with enough water to rival a tsunami. Resulted in a clean microwave with a fried out motor that no longer revolved. Part came quickly. Took cover and bottom off to get to the part. One screw held it on and a plug. Removed those, put on new part and she was good to go. No trip to home depot today.

Arcing had caused burned turntable and melted connection to sec. motor.

Plate stopped rotating - discovered plastic piece that spinner fit into was broken

Remove 2 Philips Head screws on left side of microwave. Remove 3 Philips Head screws from bottom rear of microwave. Remove 4 security screws from back of microwave (holding the cover to frame). These are the security type tips that are like a Torx bit, but need to be hollow in middle to accommodate pin in center of screw. Then back plate of microwave with heavy transformer still attached slides up and away. The wires aren't long enough to allow it to rest flat on the bench, but weight is low so it's easy to hold it upright while removing the motor unit. Separate connector from motor (simple) Remove motor by unscrewing 1 phillips head screw and rotating counter-clockwise a tiny bit. Remove Motor. Reverse steps to re-assemble. Note that there are a series of tabs at the bottom of the back cover that fit into holes in the baseplate of microwave. It can be a little tricky to line them up with the weight of the transformer, but it's not too bad. Once lined up, it drops in nicely and all the various screw holes line up. The microwave is a bad cooker when the plate doesn't spin. This simple and inexpensive fix saved me from having to buy a whole new oven.

Pried cover off bottom-center of microwave. It seems to be either glued or lightly tack welded. Removed 2 small Phillips screws to remove motor. Disconnected electric feed by hand. Don't let go of electric wire or small screws. They will be hard to retrieve from behind the rest of the metal base. Reverse process to install new motor. Didn't try to put small cover back on.

I looked up the part number, with shipping it came to $16, and in one minute of installation time, I just gently pushed the button into the front using the original springs that pushed the button back out, and it just clicked into place, the microwave back in action.

Inserted spring on middle post on button back side. Pushed button/spring into hole on front of microwave until clips engaged and snaped into place.

Door button - the one you push to unlatch and therefore open the door, was broken.

The old button fell out because the "tabs" on the end of the posts that come out from the button had broken off. These "Tabs/posts" hold it in place - you'll see how when you look at it. All that was necessary was to put the springs from the old one onto the new one. Make sure to put the thing in right-side up; there are two "tabs/posts" on the top side, and one on the bottom. Gently slide it into position as nearly straight as you can, squeezing the "posts" until they clear the front of the opening. Continue to slide in EVENLY until you feel the part "click" into place. That's it! I recommend cleaning out the area fully before installation, with a a god household cleaner, and also putting a thin coat of some sort of lubricant on the part before you put it in. (You won't be able to do that after it's installed.)

Unplug.Take off the external cowling from the back of the unit by removing the torx security screws. Tip: instead use a thin screwdriver blade to unscrew the torx screws, or knock out the center pins of these screws. Remove the bottom panel. The replacement motor is attached with one phillips screw, re-attach wires to motor - polarity doesn't matter. Re-assemble and you're finished.

Take off cover then the bottom. Transformer is on the bottom plate and wires won't let it come all the way off, too many wires to pull off so will have to position the bottom plate so you can get to the motor. Remove 1 screw on motor and remove motor. Install new motor connect wires replace bottom plate, replace cover. All done (hope & pray it works ok) mine worked perfect. Hope this helps.

Turntable quit turning

Overall repair quite simple. Removed screws from the sides and rear of the microwave, then removed cover. Next, removed only the screws to separate the bottom cover. Removed the one screw in the AC Synchronous motor to remove the motor (had to use small screwdriver through a vent slot in the bottom to remove the screw). Unplugged and removed motor. Installation is the reverse of removal. Note: on the back of my appliance were 4 torx screws with a tamperproof pin in the center. I used the rotary tool to grind out the pins so I could use a regular torx bit instead of ordering specialty bits.
