I saw a similar post (different model #) in 2012 and Brent recommended 3 switches that I see available on this site. Can someone review and recommend that these 3 switches for this model # are a possible solution? We have replaced the main control board twice and the problem continues. Microwave at random times will beep, or lock, or turn on and run. Many thanks!

The "main control board" that you replaced, did that come with the touch panel?

I'm not saying it couldn't be the door switches, but to me it sounds more like a faulty membrane switch/touch panel. They have very tight tolerances inside and are subject to heat and moisture which can cause them to malfunction. Many times the computer and the touch panel are sold separately.
