What to do if my LG Microwave Oven does not operate at all, and the display window doesn't display any figures?
- P
  Patricia ParksAug 12, 2025
  If your LG microwave oven doesn't operate, and the display window shows no figures, it could be due to a malfunction of the monitor switch or a shorted contact at the primary switch, or malfunction of secondary switch, or defective high voltage capacitor, or defective high voltage transformer. Replace the fuse, primary, monitor, secondary switches, and RELAY(RY2) of P.C.B Assembly. Replace the high voltage capacitor, or high voltage transformer. Check continuity of primary, monitor, secondary switches, and RELAY(RY2) of P.C.B Assembly.

  If your LG Microwave Oven isn't working properly after plugging it in, the microcomputer might be scrambled. To fix this, unplug the oven from the 120-volt outlet and plug it back in. This will reset the microcomputer.

  Sparks can occur in your LG microwave oven if you are using metallic ware that touches the oven wall. Avoid using metallic ware for cooking unless the cooking guide allows it. Also, do not use ceramic ware trimmed with gold or silver powder. You can also use plastic wrap or a lid. Stir food while cooking.

Why my LG Microwave Oven output power is too low?
- K
  Kelly KellyAug 23, 2025
  Low output power in your LG microwave oven can be caused by low AC input voltage. Try using the microwave oven at adequate line voltage. Alternatively, the food may require a longer cooking time, which is not a defect.

  Joshua TerryAug 28, 2025
  If your LG microwave oven display shows all figures set, but the oven doesn't start when you touch START, it could be due to a defective secondary switch, PCB assembly, fan motor, or oven lamp. In such cases, replace the secondary switch, PCB assembly, fan motor, or oven lamp.

What to do if my LG LCRT2010ST doesn't have microwave oscillation, but the oven lamp and fan motor run?
- V
  Vanessa BaxterAug 31, 2025
  If your LG microwave oven's lamp and fan motor run, but there's no microwave oscillation, it could be due to a defective PCB assembly or magnetron. Other potential issues include the high voltage transformer, capacitor, or diode. In such cases, replace the PCB assembly, magnetron, high voltage transformer, high voltage capacitor or high voltage diode. Also check the high voltage transformer and disconnect the wire leads from relay 2 and check continuity of relay 2 while operating the unit.

Why is the output of my LG LCRT2010ST lower than 90%?
- R
  Ryan FranklinSep 4, 2025
  A lower than expected output (less than 90%) from your LG microwave oven can be due to a decrease in the power source voltage or a defective magnetron. It is suggested to contact local electric power utility co. or a qualified electrician. Disconnect the wire leads from relay 2 and check on and off time with multitester. Replace the magnetron.
