LG Microwave Sparking and Power-Cycling Display Issues: Safe Checks

Treat sparking together with power cycling as a stop-and-scope problem, not as proof of a bad magnetron, inverter, control board or fuse. LG says sparks can come from food carbonization, metal or metallic-trim cookware, an incorrectly installed rack, an empty cavity, or a damaged cavity; continuing sparks or cavity damage require service.
