I have an American Standard furnace that's about 2 years old and a few days ago the heat stopped working. The heat has been working off and on for a few days. It was working all day today until about a half hour ago, all that was coming out was air from the fan inside the furnace, and when I tried to shut it off it wouldn't shut off. If anyone has any idea what the problem might be I would be very grateful.
Also when I turn the heat on the flame will light shut off real quick and relight. And it will keep doing this till I shout it off.
