Question about Emerson MW8778 Microwave Oven
I suspect the interlock monitor switch in your microwave oven is the culprit. This is one of several switches operated by the door latches. It's designed to blow the fuse if you try to run the microwave with the door open. The switch is probably stuck, or is out of adjustment (which can happen if the oven door gets closed hard), and when you restarted the oven it blew the fuse. It is possible to adjust or replace the switch as necessary, but it might not be worth it. You should have a professional do the repair as there's a chance of microwave leakage if repairs involving the door aren't done properly. Between labor and parts, the repair cost might come close to (or even exceed) the replacement cost for a small oven.
Hope this helps, and thanks for using Fixya!
