How can I fix my noisy microwave Sharp R-959M/R-98STM-A?
When I use my microwave in Convection mode, it has become very noisy and sounds as if it is the turntable which is making a loud rumbling noise. However, when I use it in Microwave mode (when the turntable also rotates), it does not make any noise at all. Why is this and can I fix it?
