It's been a few weeks now and I have updates on what's been going on. The knocking has slowed down a lot but I have a new thing going on. A few days after christmas for whatever reason a fuse blew and knocked the power out to half of my house, now where the stuff is going on is the side that was not affected. So we fix the fuse and later I'm in the kitchen cooking supper, and the microwave turned on by itself. Well I thought it had to do with the power earlier that day but thinking about it, the kitchen was not affected, and I just blew it off as a fluke.
Then about 5:00am I hear it going off so I get up and look, the light was on, well I can't explain that away so I went back to bed. This keeps going on for a day or two between 4 and 5 am, so I told my husband about 2 weeks later what was going on and he blows it off like nothing, until my niece tana woke us up on friday morning to ask why the microwave was going off, I looked at Tim and told him to explain what happened, and he could not find a logical explanation for it.
So for now at night I leave the door to the microwave open. Really I don't know if it is part of what's been going on or if it is just a malfunction with the microwave, but it's never happened before. I am just curious if anyone has a good guess on this?
