Chosen Solution
I have an over the range microwave. A rattling noise can be heard when the turntable is in use. When the turntable is turned off there is no noise. I have tried removing the glass plate and turntable roller not no avail. Should I remove the bottom of the microwave to gain access to the turntable mechanism ?
Hi, Check for flat spots on the rollers on the roller ring. (It is what the turntable rests on.) If there are flat spots, unfortunately the ring has to be replaced as there are no individual rollers available
Had the same problem which was solved by cleaning the the entire track and wheels under the turntable. Amazing how much sound emanates from such a simple problem. Of course you should be very careful to have the parts placed correctly after they are removed for cleaning.
Read the problem folks…it going to be the motor ir plastic piece between the plate and motor or both
Hello Richard - we have the same problem. Cleaning the wheels etc makes no difference. The problem is inside the oven itself, perhaps in the motor or thereabouts. We removed the turntable and the wheels and turned the microwave on and the noise still occurred. Quite loud and annoying. Only began after warranty ran out. Sorry I’m no help - can only commiserate.
I have the same problem. I replaced the drive motor (~$50 part) and the noise is the same…or worse. Any suggestions?
I had the same popping noise only when I put in the glass tray. I did clean it with dishwahser solution but still the same afterwards. Only when I cleaned it with antistatic spray (same used for cleaning computer screens) did the popping sound stop. Hope this helps, it saved me a trip to the technicians.
Same problem with thumping noise in GE over the range Microwave. Visual inspection revealed nothing but running my finger around track that ring rides on located a small bump which blended perfectly with the bottom track. Cleaned the track, wheels and underside of glass turntable. Voila’ problem solved.
This may not solve your problem, but everyone has cooking spray (any type of oil will work to diagnose where the problems is) and you do not need to tear into your machine and no repairman involved. My problem was the plastic ring with wheels that goes under the turntable. The little wheels rotate on a little axle, and applying a drop of hi temp cooking spray to each wheel/axle did the trick. Now, it’s absolutely SILENT.
I sprayed silicone oil down the opening of spinning table plastic gripper on my Samsung microwave. Stopped the noisy vibration.
We use our microwave to make bacon for breakfast, the microwaveable cooker is so large that our microwave’s turntable cannot rotate, so after a while our microwave starting making bumping sounds when we used it. I found your page here while searching for possible reasons online! I did what people here had suggested, I checked for flat on spot/s roller wheel/s, found none, I wiped all the roller wheels clean, and also cleaned the track that the rollers wheel travel on the microwave. Thrilled to report, no more bumping sounds, our West Bend Microwave is working like a charm!
I see that this is a question from 2015. Back to the future in 2022, I had the same problem, a knocking sound as the turntable rotated. With the turntable removed, no noise! I cleaned the roller track as per previous answers and the noise disappeared. Good question, correct answers! Many thanks.
