Microwave Power Blew Out - Kenmore Elite Model...

Question

OTC 2004 Model. Just finished heating 2 meals - 1 for 10 minutes & 1 for 2 minutes. Had the door open for a minute or so and put another dish in the microwave. Immediately upon closing the door a flash occurred and the power went out on the microwave. I replaced the ceramic fuse (based upon recommendations from this site) - still nothing. Any suggestions or recommendations would be greatly appreciated. The flash seemed to occur from behind the area where the door latches.
