King 5500M Problems no heat

Well I just got a call from My wife since I am out of town and I guess the stove is making a very loud noise and I have no heat. With the setting on heat range 1 it usualy keeps the main living area around 75 degrees and as of an hour ago it was down to 55 degrees. So she had to kick on the Propane fernice, $2.50 a gallon ouch. Kinda sucks since I have only had the stove for 3 weeks. My guess is it is the room fan/ Distribution fan, since the fire was still going. Or is there other things it could be.

I will be calling US Stove Company on friday, but I would kinda like to know what I am talking about when on the phone with them. Thanks

What ended being the problem with your pellet stove ?.
