Quick guide to diagnosing microwave oven issues, overheating, or logic locks.
We test high-voltage diodes, check magnetrons, and verify starting relays to restore heating. If the oven fails to heat, we inspect the magnetron, test the capacitor, and check the high-voltage diode.
We replace damaged waveguide covers, clean carbon deposits, and seal exposed metal areas.
We check tray alignments, inspect synchronous motor windings, and replace faulty turntable gears.
