Our 2014 LG microwave suddenly stopped working mid-2019 and LG wouldn't cover the cost to repair it because we didn't have the proof of purchase for the microwave. (Overhead mounted microwave in a new house, but we are the second owners). I was very annoyed with the prospect of potentially having to purchase a new $200+ microwave, but after some research I realized it might be pretty simple to fix. There are definitely some electrical dangers involved with this, so if you do find yourself replacing this component, take the time to thoroughly research the process and be safe. SearsPartDirect makes it easy to find the exact parts for your appliance and the replacement Magnetron I received worked perfectly! Hopefully this one lasts longer than the original.
