Question about Sharp R-1405 / R-140 Microwave Oven
All buttons, lights, fan & carousel work but no heat
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.

It sounds like you may have an intermittent door switch or loose door switch mount.
Does it work differently when you wiggle the door?
