Our Sharp convection microwave(original to coach)is the noisiest, clatter & rattle box I have ever heard.
Tried to eliminate all possibilities by

1)We took out all the loose grates & pans inside & it still rattled.
2)We put a pillow in it, no luck.
3)We thought it was coming from underneath & we stuffed stuff under it to no avail.
4)We pulled it out, took off the bottom & looked around & nothing there to rattle.

It works fine but it is the last rattle to conquer. Anyone else have this problem & did you solve it without buying a new one?
Thanks,
Tere

We removed ours because it took up a lot of space and Susan didn't use the convection feature, since we seldom use our gen and are never plugged in.

We replaced it with a smaller microwave and I built two drawers to fill the empty space. She really loves the extra storage space.
