In March of this year (2023) a microwave I had had for a little over a year stopped working.  Very frustrating.  So I bought my current unit within a week or two. Because of my previous experience, I purchased a 5 year warrantee, which was not available on the other brand.  So far, my new LG microwave is working well, and I have no complaints.  Something funny happened a few days after installation.  The door did not open all the way until we got the fridge to stand up straight, and as soon as I was able to open the door, I found all the detailed instructions for the buttons, for example, Reheat 1 is dinner plate, etc.  I love that the instructions are right there on the door. So far, so good.  I will know better when, after 2 or three years, it is still working!.
