Common LG microwave problems we fix
Runs But Doesn't Heat
A microwave that hums, lights up and spins but leaves food cold has lost its high-voltage circuit.
- · Failed magnetron
- · Blown high-voltage diode or capacitor
- · Burned-out thermal fuse
- · Faulty door interlock switch cutting the HV circuit
Sparking or Arcing Inside
Arcing is a stop-using-it-now symptom — but it's usually repairable, not fatal.
- · Damaged waveguide cover
- · Chipped interior paint exposing metal
- · Failing magnetron antenna
- · Metal residue on racks or turntable supports
Turntable, Door & Latch Problems
Built-in and over-the-range units take heavy daily use — mechanical parts wear first.
- · Worn door latch assembly (unit won't start)
- · Failed turntable motor
- · Broken door hinge or spring
- · Faulty door switch sequence
Dead or Erratic Control Panel
Ghost touches and dead keypads on built-in microwaves are almost always electronic, not user error.
- · Failed membrane keypad
- · Control board fault
- · Blown internal fuse
- · Steam ingress from poor venting
