I have a Samsung microwave with a really weird bug. If the door is just a few millimetres ajar, it turns on by itself. It's not just mine either, a lot of reviewers point out the same. It seems to be a design flaw. It's not a huge issue, since I'm not exactly in the habit of positioning the door in a half-open state.

My guess is that they have some broken/inverted logic related to the "turn off if the door is open" feature.

The article describes such an issue but the assures that the oven magnetron doesn't run. Maybe it's a similar problem where the turntable and light come on in that situation.

I remember this flaw in a Samsung microwave from ~2007-2008. It freaked me out when I triggered it while trying to quietly close the door.
