A microwave that won't heat, sparks behind the panel, or just goes dark is frustrating — and often far cheaper to fix than to replace.
A failed magnetron, high-voltage diode, or thermal cutout is usually behind a microwave that runs but stays cold.
Worn waveguide covers, paint chipping inside the cavity, or metal scorch marks cause dangerous sparking.
A stripped drive coupler, jammed roller ring, or stalled turntable motor leaves the plate sitting still.
A blown main fuse, faulty door switch, or bad control board can leave the keypad completely unresponsive.
Overheating from blocked vents or a failing thermostat trips the safety circuit mid-cycle.
A worn keypad membrane or moisture in the control panel makes some keys stick or fail entirely.
