What does E41 error mean on a Samsung CM1919 Microwave Oven?
- C
  Christopher SantosSep 12, 2025
  If your Samsung Microwave Oven displays error code E41, it could be due to a Main Relay (RY1) or Power Relay (RY2) failure, loose lead wires of relay, Primary or Monitor S/W failure, loose lead wires of Primary or Monitor S/W, or H.V.Trans input power sensing circuitry failure. Check the Main Relay (RY1), Power Relay (RY2) Primary S/W and Monitor S/W and replace if defective. Check if lead wires are loosened and connect firmly if loose. Check the circuitry and replace if defective.

What to do if Samsung CM1919 timer counts down but no heat?
- K
  Kristen LeeAug 22, 2025
  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 CM1919 Microwave Oven does not accept key input?
- K
  Kelly WilliamsAug 25, 2025
  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.

Why Samsung Microwave Oven stirrer does not rotate?
- L
  Linda PrattAug 27, 2025
  If the drive motor in your Samsung Microwave Oven isn't working (the Ass’y stirrer doesn't 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 the ass’y stirrer.

What to do if my Samsung CM1919 shows E3 error?
- M
  Matthew HuffAug 28, 2025
  If your Samsung Microwave Oven displays error code E3, it could be due to overheating inside the cavity because there's no load or too little load. Try plugging the power cord in again. Also, check for any blockages around the air exhaust area or ventilation openings. If the error persists, check the resistance of the Thermistor sensor and replace it if defective. The ventilation motor might be failing and causing the magnetron to overheat; replace the motor if necessary.

Why is my Samsung Microwave Oven taking longer to cook food?
- S
  sarah37Aug 29, 2025
  If your Samsung Microwave Oven is not heating food properly, and the cooking time is longer than usual, it could be due to several reasons. The power source voltage might be decreased. Check for open or loose wiring in the magnetron filament circuit. The magnetron itself might be aging, or there could be defective high voltage components such as the H.V. Transformer, H.V. Capacitor, H.V. Diode, H.V. Fuse, or the Magnetron. Consult an electrician and check the high voltage components; replace them if defective.

  staffordwendySep 18, 2025
  If your Samsung Microwave Oven displays 'E1', it could be due to an improper input power frequency or a defective Ass’y Main P.C.B. Check if the power frequency is 50Hz. Replace the Ass’y Main P.C.B or MICOM.

Why did the lamp go off in my Samsung CM1919?
- C
  Courtney AndersonSep 13, 2025
  If your Samsung Microwave Oven lamp goes off, it could be due to a loose lead wire or open lamp filament, misadjustment of the latch switch, or a defective primary latch switch. Tighten the lamp lead wire or replace it with a new lamp.

What does E42 error mean on a Samsung Microwave Oven?
- G
  ghoffmanSep 9, 2025
  If your Samsung Microwave Oven displays error code E42, it could be due to a Power Relay (RY5) failure, loose lead wires of Power Relay (RY5), a Primary or Monitor S/W failure, loose lead wires of Primary or Monitor S/W, a blown fuse (10A) on the neutral area of the Assy Noise Filter, or a H.V.Trans input power sensing circuit failure. Check the Power Relay2, Primary S/W, Monitor S/W or Fuse and replace if defective. Also, check if lead wires are loosened and repair as necessary. Check the circuitry.

Why is my Samsung CM1919 sparking?
- L
  Laura OrtegaSep 5, 2025
  If your Samsung Microwave Oven is sparking, it is likely due to metallic ware or cooking dishes touching the oven wall, or ceramic ware trimmed with gold or silver powder. Ensure you are using proper cookware and avoid any items with metallic trimming.
