The fuse to the magnetron may be blown or the mag it's self is gone. if the door switch was bad the unit wouldn't rotate the carousel. if it is the fuse (check with a multi-meter and check continuity across both side of the fuse, acheap one will do) if it is good, time to replace the micro, as they are cheap and repair would cost more than to replace. hope this helps.

Sharp carousel microwave model # 508ak has power but does not heat food when you press the start button. thanks in advance!


9 times out of 10 this is usually this is a bad magnetron, the other time is sometimes a bad high voltage diode. See components section. Q - My microwave is running and sounds like it is working but will not heat up anything.
A - Many thing can do this but, common things are....loose high voltage wire.....poor solder joint on board.....magnetron.....power relay.....

Q - The microwave display counts down and the inside light is on, but nothing is heating and the fan is not running.
A - This most commonly is a bad door switch, other possible problems are a faulty relay or solder joint on the power module, but a bad door switch is most common.
thanks.

I don't hear the fan, the carousel doesn't spin, nothing works but touchpad & light


It sounds like you may have an intermittent door switch or loose door switch mount.

Does it work differently when you wiggle the door?

Fan runs when door is closed - no heat


This is normally 1 of the interlock door micro-switches not working.
