Possible Causes of Microwave Problems
A microwave that runs but doesn't heat has almost always lost its magnetron — the component that generates microwave energy — or has a failed high-voltage diode or capacitor in the same circuit. Sparking is usually caused by a damaged waveguide cover, metal debris inside the cavity, or a failing magnetron near the end of its life. A microwave that won't start at all often points to a door switch that isn't signaling the door is fully closed, even when it appears closed.
