If your Sharp Microwave Oven's monitor fuse blows, examine the secondary switch, door sensing switch, secondary interlock relay (RY2), primary switch, and monitor switch before replacing the fuse. Also, when replacing the monitor fuse, be sure to replace the monitor switch and primary switch as well.
