"Microwave Sparking Inside" — Dallas same-day fix

What causes “microwave sparking inside”?

Stop using it immediately. Sparking is almost always a burned or missing waveguide cover — the mica or cardboard rectangle on the interior ceiling that costs about $15 to replace. Ignoring it lets the arc damage the magnetron, turning a $15 fix into a $200 repair. Arcing can also come from carbonized food splatter on the cavity walls or a failing stirrer motor cover.

DFW context for microwave repair issues

OTR microwaves above gas ranges in DFW kitchens see more grease vapor than most equipment is designed for, because we cook big and we cook often. Grease saturates the stirrer cover and the waveguide until it arcs during a normal cycle and burns the mica shield. Door interlock switches wear out mechanically after enough hard slams — a very common family-kitchen failure. Rental units near UNT, TCU, SMU, and UT Dallas take another kind of damage: liquid spills into the touch membrane during shared cooking.
