Microwave Oven Sparking Inside
A Microwave Oven with the "Sparking Inside" fault usually shows it through visible sparks or arcing near the cavity wall, a burning smell during use, and flashes near the turntable support. This is typically traced back to metal or foil residue inside the cavity, a damaged mica waveguide cover, and a chipped enamel spot exposing bare metal. A technician resolves it by inspecting and replacing the mica cover and checking the cavity for damage before further use.
