LG microwaves are known for their efficiency, reliability and performance. However, like all other home appliances, we can face issues with LG Microwave too, and our LG microwave may stop working. In this brief blog, we will discuss the common reasons why your LG Microwave Not Working When You Can Contact LG Microwave Service Center in Bangalore and will also provide you with troubleshooting tips to help you identify and try to fix the problem by troubleshooting the process.

Common Reasons: Why LG Microwave Not Is Not Working?

Before we start repairing LG Microwave, we need to know why the microwave is not working.

LG Microwave Power Issues: If your microwave is not working, there could be a power issue. If there is no voltage supply in the microwave, the microwave will neither turn on nor do anything. This power issue can be due to faulty cable, blown fuse or loose plug connection.

LG Microwave Magnetron Issue: The magnetron is an important part of the microwave. It uses electrical energy to generate sufficient amounts of heat to warm food stuffs. If it is damaged or faulty, then the microwave will not heat the food material kept inside a microwave.

LG Microwave Defective High Voltage Diode: High Voltage Diode is used in the microwave to convert AC voltage to DC, so that the converted energy can be used for generating heat. If Diode is faulty or damaged the energy will not be produced and the microwave will not provide any heating to material kept on a plate.

Faulty Turntable Motor: The turntable motor is responsible for rotating the plates with the support of the table kept in a microwave. If the motor is faulty or damaged or not working it will not rotate the table hence food will not be warmed equally.

LG Microwave Blocked Ventilation System: Always a blocked ventilation system can make the microwave from working properly. So regularly cleans the ventilation system.
