I have a nordyne furnace in a doublewide. I replaced the 8" plastic piece below the vent pipe because one of the two fans was not working. Now after putting the new unit in it does not work? What did I do wrong?

Need more clearly described information to be of much help here.

Does not work... be more specific.

The red light is blinking two times. This means there is a pressure switch problem. I replaced the bad fan unit, but the new one does not work.

Is there a reset button I should push?

If the inducer isn't running, the pressure switch will not engage. Is the motor wired correctly? Why was it replaced? Is it being powered?

The inducer was replaced. That is the motor I was referring to . It was replaced because one of the fans was not turning. I put the new inducer in and the light still blinks 2 times which means the pressure switch is open. I am stuck.

Is the pressure switch hose connected to the new inducer in the same fashion as it was to the old one? Use a straightened paper clip to check the hose connection port on the new inducer for blockage. Also, try this: set thermostat to demand heat. Using a vacuum cleaner with a hose attachment, hold the end of the pressure switch hose near the end of the vacuum cleaner hose (don't seal them together!). See if unit starts heating. If it does, you may have a leaky seal where the inducer mounts.
