I cleaned our microwave as usual and it works great except now when the turntable goes around it makes a noise. If I take the glass turntable out along with the little plastic ring with the 3 wheels on it there is no noise.

I put the ring with the 3 wheels and the glass plate back in--------turn it on so the turntable goes around and it starts to make a grinding or poping noise.

Could the ring with the wheels be bad????????????

Thanks for your reply - I cleaned wheels and axels on the ring the glass plate sits on and solved the problem
