Why is my LG MB-4343C not heating properly?
If your LG Microwave Oven appears to be running but isn't heating food properly, it could be due to a power source voltage lower than 90%. It is suggested that you contact your local electric power utility company or a qualified electrician. It also may be caused by a defective P.C.B assembly or a defective magnetron, which would need to be replaced.
Why my LG MB-4343C Microwave Oven doesn't turn on?
If your LG Microwave Oven doesn't operate at all, and the display window doesn't show any figures or accept input, it could be due to several reasons: a blown fuse (replace the fuse), a defective magnetron thermostat (replace the magnetron thermostat), or a defective power supply cord (replace the power supply cord). Also the high voltage capacitor might be defective and needs to be replaced.
Why is my LG MB-4343C sparking?
Sparks in your LG Microwave Oven can occur if you're using metallic ware that touches the oven wall. Avoid using metallic ware for cooking, unless the cooking guide says it’s safe. Also, ceramic ware with gold or silver powder trimming can cause sparks, so don't use cookware with metallic trimming.
