“Carrier Performance 93 2 stager” , posted Wed 26 Sep 10:41: ______________________________________________________________________ Is this furnace or line up of these 2 stage furnaces in the good books?

Is the ceramic collar loose or cracked? That will allow the flame sensor to ground and interrupt the signal to the control board and it will recycle 3 times . Good luck…john…austin,texas camman “Re(6):Carrier Performance 93 2 stager” , posted Thu 27 Sep 12:30 ______________________________________________________________________ Thanks for your help. I replaced the flame sens. and now have 3.6 micro volt reading,also took burner assembly out and washed in hot soapy water and now have a smooooth ignition instead of jumpy or none at all. We shall see and wait how good this fix is.
