If your Samsung Microwave Oven does not accept key inputs for programming (CM1929/1629/1329 models), it could be because the key input is not in sequence, there's an open or loose connection of the membrane keypad to the Ass’y PCB, the membrane panel is shorted or open, or the Ass’y PCB is defective. Refer to the operation procedure and replace the PCB main.
What to do if Samsung CM1629 Microwave Oven timer counts down but no 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 turn on), it could be due to an open or loose connection in the high voltage circuit, especially the magnetron filament circuit, or defective high voltage components like the H.V. Transformer, H.V. Capacitor, H.V. Diode, H.V. Fuse, or Magnetron. Adjust the door and latch switches. Check the high voltage components according to the component test procedure and replace them if defective.
Why Samsung CM1629 can program but timer does not start?
If your Samsung Microwave Oven can be programmed, but the timer doesn't start, it could be due to defective circuitry in the Start function of the Main P.C.B Ass’y or loose lead wires. Check the circuitry of the Start function of the Main P.C.B Ass’y and replace it if defective. Adjust or repair any loose wires.
Why isn't the turntable rotating in my Samsung CM1629?
If the drive motor in your Samsung Microwave Oven isn't working, causing the stirrer not to rotate, it could be due to an open or loose wiring of the turntable motor, a defective turntable motor, or a defective ass’y stirrer. Check the wire of the drive motor, replace the drive motor, or replace the ass’y stirrer as needed.
Why does my Samsung CM1629 Microwave Oven not operate and return to plugged-in mode?
If your Samsung Microwave Oven does not operate and returns to the plugged-in mode, it's likely due to a defective Ass’y PCB. Replace the PCB main.
Why does my Samsung CM1629 stop during cooking?
If your Samsung Microwave Oven stops operating during cooking, it could be due to the operation of the thermal cutout (on the Magnetron or Cavity) or a non-rotating fan motor. Adjust the door and latch switches. Replace the fan motor.
Why won't my Samsung Microwave Oven accept key inputs?
If your Samsung Microwave Oven does not accept key inputs (program), it could be due to the key input not being in sequence, an open or loose connection of the membrane keypad to the Ass’y PCB, a shorted or open membrane panel, or a defective Ass’y PCB. Refer to the operation procedure. Replace the PCB main.
