Keeps double blinking. I found the error in tha manual and it states "Pressure Switch Open with Inducer On". I think I found the Pressure switch but I don't see any knob, buttons or anything to adjust. So what's the fix?

It's getting a little chilly in here. :rolleyes:

See "what is a pressure switch" here.

I think I figured it out. :) The tube that was connected to the inducer/blower was allowing air to escape. I pinched the tube closed a little and stopped the air flow and it started right up.

I have a Nordyne furnace in a doublewide. I replaced the 8" plastic piece with the 2 fans in it because one fan would not turn. Now after being all back together it does not work. Why?
