A friends Panasonic Microwave Oven has started Sparking. Did some searching and found Fix Your Sparking Microwave Oven For Only $5 https://www.youtube.com/watch?v=EZmKTpaA… Seems the problem is the Panasonic Mica Waveguide Cover. None of the other Microwave Ovens I have seen have this type of Waveguide Cover. Believe they have perforated metal? Since the Mica Waveguide Cover can cause sparking problems. Can it be either cleaned or replaced with a more permanent material? Thanks Ken
