What to do if my Samsung C100R timer counts down but doesn't heat?

If your Samsung Microwave Oven's timer starts counting down but there's no microwave oscillation (no heat, but the oven lamp and fan motor are working), it could be due to several reasons: * Misaligned latch switches. * Loose connections in 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, H.V. Fuse, or Magnetron. * Loose wiring of the power relay. * A defective primary latch switch. * A 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 any defective components. Replace the PCB main.
