The inflow duct of my forced-air furnace seems to be blowing outward instead of inward.
What are the most likely causes ?
After the hurricane I had to change the electronic igniter since it got wet.
Could water damage be the cause of this problem ?
Ive heard I should check the dampers.
What are they and how do you check them ?

Did the gas vale also get wet? If so it also needs replaced.

Water may have damaged the motors windings, or the run capacitor.
