    Why is the output power of my LG Microwave Oven too low?
    • R
      Rebecca MccannAug 12, 2025
      There are a couple of reasons why the output power of your LG microwave oven might be too low. It could be due to a low AC input voltage, in which case you should use the microwave oven at adequate line voltage. Alternatively, it may not be a defect, and the food may simply need to be cooked for a longer time period.

      Daniel FranklinAug 27, 2025
      If the display shows all figures set, but the oven does not start cooking when the desired program times are set and the START pad is touched, it could be due to a defective secondary switch or a defective PCB assembly. Replace secondary switch. It may also be necessary to replace the PCB assembly.

      To prevent a blown fuse or breaker when using your LG microwave oven, avoid using other electrical appliances at the same time. Inserting many plugs into one outlet and using them simultaneously can overload the circuit.

    What to do if my LG MS-324DL fuse blows?
    • D
      Dawn BrowningSep 12, 2025
      If the fuse blows, it could be due to a malfunction of the monitor switch, a shorted contact at the primary switch, or a malfunction of the secondary switch. Replace the fuse, monitor switch (with the door closed). It may also be necessary to replace the primary, monitor, and secondary switches, along with the RELAY(RY2) of the P.C.B Assembly.
