We have a noise when plugged in to AC power (20A at home or 30 at campground). It comes and goes, and can get quite loud. I have had Jason look at it twice, and he couldn't get it to make noise. When we unplug for awhile, it immediately goes away, and usually won't reappear after plugging in for awhile, unless we don't give it enough time.
Anyone else have this problem? It is a buzzing noise. Tom and Carol Lamb
