    Why is my LG MC-766Y Microwave Oven sparking?
    • B
      Bobby AdkinsAug 20, 2025
      Sparks can occur in your LG microwave due to several reasons: * Using metallic ware or allowing it to touch the oven wall. Avoid metallic ware unless permitted in the cooking guide. * Using ceramic ware trimmed with gold or silver powder. Do not use cookware with metallic trimming. * Sometimes, sparks can be managed by wrapping thinner parts of the food with aluminum foil, using plastic wrap or a lid, or stirring the food (like soup, cocoa, or milk) occasionally during cooking.

    Why is the output power too low on my LG Microwave Oven?
    • M
      Matthew MyersAug 26, 2025
      Low output power on your LG microwave could be due to: Low AC input voltage. Use the microwave oven at adequate line voltage. Alternatively, it might not be a defect; the food may simply need a longer cooking time.
