My 1994 Sharp Carousel Microwave/Convection Oven, Model # R-9H84B, does not heat. The fan and display work and the turntable does not turn. It works properly if I pull slightly on the door handle while it is running. Could that be the door switches, and how can I replace them? There are four screws holding the cover on.
