I watched this horror movie in the 70's I think. It was about this group of college age kids at this house where they get locked in by something supernatural. In one scene, someone gets electrocuted in a window? Anyway, it turns out that in the basement is an entrance to hell, and somehow it got opened. The devil got out and he looked like Col Sanders, an old fat guy in an all white suit. I though it had "House" in the title but I'm not sure. I know it's not "House" with William Katt.

Chosen answer: The movie you're after is "The Evil", starring Richard Crenna. Its American title is "The Evil Below" I think.
