Quick answer: LG solo, grill and convection microwaves that run without heating usually have a failed high-voltage diode or capacitor, a weak magnetron or a door-switch fault. Turntable and sparking issues are cavity or drive-part problems.
How LG Microwaves Fail
Heat comes from a magnetron powered by a transformer, capacitor and diode, all guarded by door switches. Grill and convection models add heating elements and relays that fail separately from the microwave circuit.
