Thanks to modern microwaves, we can taste hot meals every day, without taking a lot of time to use a cooktop. So, when you head for an easy meal, and find out your microwave doesn’t work, it may feel like your world is crashing down. This article will help you to find issues and repair. We have tested all issues on microwave LG LMV1683 ST.
Check door switch. The microwave door switch is a piece in the microwave to stop the oven from running while the door is open. If this switch is damaged, the microwave may look like it still works with the fan and rotation motor still functioning, but the food won’t warm up.
Check diodes of your LG microwave. If the microwave is running but not heating your food, another possibility is the diode has burnt out. A diode allows the electrical current to flow in only one direction. If the diode fails, it could mean there is a short, which will allow the current to flow in both directions, or only part way in one direction.
Check the heating element. Another problem with not heating microwave could be magnetron. The magnetron is responsible for heat production within the appliance, and a malfunctioning magnetron could blow a fuse, ultimately causing other functions of the microwave to fail. Unplug the microwave, remove the cabinet and discharge the high voltage capacitor to protect yourself from electric shock.
