Sharp Microwave Doesn't Make Anything Hot

Have a sharp microwace model R308NW.  Everyting seems to be working i.e. timer counts down, light is on, carosel turns, and the whole thing hums. but it does not change the temperature of anything put inside.  It's not a fuse.

there are relays on the control module that activate the high voltage section to run the magnetron that heats the food. the failure could be the relay, one of the door switches, the transformer, the diode, the capacitor or even the magnetron.

it's highly recommended tat you take it to a shop, this section is extremely dangerous to work on.
