Repairing the lightening bolt microwave

Our Panasonic dimension4 NN-C2000W microwave sparked and made some sad noises. An unexpected piece of metal was in he bowl. Afterwards the microwave didn’t make the same familiar noises.

Upon taking off the cover to the microwave generator, the board had burn marks (carbon) that was now causing the microwave energy to bounce back to the generator, instead of out into the food.
