  Jonathan SanchezAug 19, 2025
  If your Samsung Microwave Oven timer starts counting down, but there's no microwave oscillation (no heat, but the oven lamp and fan motor turn on), it could be due to several reasons: * Misalignment of latch switches. * Open or loose connection of the high voltage circuit, especially the magnetron filament circuit. * Defective high voltage components such as the H.V.Transformer, H.V.Capacitor, H.V.Diode, or Magnetron. * Open or loose wiring of the power relay. * Defective primary latch switch. * Defective power relay or Ass'y PCB. Adjust the door and latch switches. Check the high voltage components according to the component test procedure and replace them if defective. You may also need to replace the PCB main.
