Does it make the noise when you turn the oven on or just close the door?
no, when I started heating a item the sound went away, after I used the microwave the humming noise disapeared, it seems to be okay now, but what would have caused this to start humming and smelling when n oone was using the microwave? The noise was only made when the dor was closed
what other signs should I see that it might be the magnetron
how can it make the loud humming noise when we wasn't even using the microwave? What else could it possibly be? Its heating now as normal
