Sharp microwave oven carousel turntable repair 

Thanks! I am so glad this helped you!

NEWKNOWLEDGE Great idea!

THANKS. Previously my oven blew a 120 VAC fuse, and a thermal fuse, and all this happened because of a defective door microswitch which was intermittent and arcing. On the way to the beer store, along with my foldable shopping cart, I spotted a microwave oven at the curb. It was being disposed of. On the way back from the beer store, I popped this oven into my cart and took it home. It turned out that all the parts that I needed were available, 100% compatible, and still 100% working in this particular oven. So I transferred the parts and bingo my oven was up and going once again. I also removed some other working components from the scrapped oven for any possible future need. Total repair cost, $0.00.

By the way, my stainless steel microwave oven was said to be a "DEMO" oven, and so I got it for just $40. In truth, it turned out to be a "DUD" oven because the keyboard was not 100% working. Instead of taking it back to the store, I took it apart, removed the flex connector that attaches the keyboard to the control board, cleaned the contacts, reinstalled it into the control board, and bingo, it has been working 100% ever since. Total repair cost, $0.00.

I have the Sharp R1855A and my turntable seemed to be stuck. It would turn a bit and then stop and then try to turn the other way, and then stop. I took the motor apart and found nothing like what like you are talking about. I examined the gear train under a magnifying glass and it all looked good. The one area that was questionable was the pinion that drives the gear on the microwave. The grease was all burned up there. So I cleaned the gears and then lubricated them with gear oil (80/90) and then reinstalled it. That alone was worthwhile because it's now fully lubricated again. What I determined was the answer was increased drag on the tri-lobed device under the platter in the body of the microwave. The three white wheels had debris on them and the track they ride in also had debris. After cleaning the wheels and the track - voila. It works again! So it appears mine is very sensitive to debris or oils under the white wheels. The good news? You don't need to remove anything to clean it other than the tray and the tri-lobed device the tray rides on. In other words, clean the microwave more often!

@@bobjones3725 I hate having to clean anything too often. So whatever I put in the microwave oven, I make sure that a cover is included such that no food will end up on the ovens walls and/or ceiling. For instance, I held on to several of frozen dinner black plastic microwavable bowls. So if I am heating perhaps a bowl of soup, I place an empty frozen dinner bowl on top of the soup bowl. That keeps everything in the soup bowl zone. I also rest the soup bowl itself in another empty frozen dinner bowl such that once the soup is heated up, I can then remove it from the oven without having to touch the actual hot soup bowl itself. Anyhow, that sure cuts down on how often I have to clean the oven.

Hi Carmen, actually the microwave in our RV later quit working like yours and it ended up being a loose connection in the electric circuit that supplied the microwave. We plugged in a circuit tester (you can plug any other electric device into the plug you use for the microwave) and you will know if the problem is in the microwave or the electric outlet. If the outlet is good then you know the problem is in your oven.

Should've used a Volt-Ohmmeter
