We bought a house with a 2014 VC Defiant with a catalytic element. Running well. However yesterday the damper handle became loose and will not turn forward. It will turn clockwise until about 2 'o clock and counter clockwise only till about 7 'o clock. Prior to this the damper handle would stiffly more forward to close the damper until about the 3' o clock position. I am not sure if the damper is operating. The stove is cold right now but we need to use it since it is going down to freezing tonight. Should I remove the catalytic element and run it that way till we can figure it out? What should we do?
