- Waveguide: Guides the microwaves into the oven cavity.
- Antenna: Distributes the microwaves evenly throughout the cavity.
- Stirrer Motor: Rotates the stirrer fan to ensure even heating.
Common Causes of LG Microwave Oven Not Heating
- Faulty magnetron
- Damaged waveguide
- Malfunctioning antenna
- Defective stirrer motor
- Overloaded power supply
- Blown fuse
- Faulty door switch
Safety Precautions
Before attempting any repairs, ensure the following safety precautions:
- Unplug the microwave oven from the power outlet.
- Allow the oven to cool down completely.
- Wear safety gloves and goggles.
