Furnace runs constantly
My Rheem Criterion II RGPH15(1998) runs constantly. I had transformer checked (good), and installed new T-stat, but when I turn power on it fires up, and doesn't stop ! Hopefully, its' something minor, because now the HVAC guys are busy, and can't get to me for another two weeks!
Thanx,

Furnace runs constantly..
I pounded both sides of the furnace, but the blower still runs and the burners stay lit also. This furnace doesn't have the 2X4 fan control box on the side. Can it be somewhere on the Control Board?

Ok, undo the t-stat from the sub-base.. see if it stops.. if it stops, then it's the t-stat.
if not, then undo the wires from the sub base. If that stops, then it's the sub-base.
If not, then undo the wire at the furnace.. if it's stops, then there maybe a short in the wire some where in the wall.
