I have A Nordyne Gas furnace in my home, work up this morning to a cold house. I can't find my manual to troubleshoot the problem. Status light is blinking twice. I can get furnace to work by by-passing the pressure switch w/jumper wire. Could the problem be the Combustion blower assembly. This Assembly was replaced about 4 yrs. Ago.

Turn the ;ower off to the unit and try it again in a min or so. The fault codes should also be on the back of the door or on the control board itself

Thanks for your reply. Can't find fault codes anywhere in unit . Pretty sure it is Comb. Blower assembly... Now just got to find 1 on a weekend... 'bout 80$ worth of plastic..

Do you have a exact model number for the furnace?
