Question about Heating & Cooling
Typically the barbed port where the induced draft proving switch's tubing connects gets obstructed by carbon , if you ream out the port on the induced draft assembly it will allow the induced drafts switch to sense the draft motor is operational, this port needs to be reamed annually to avoid this.Typically the barbed port where the induced draft proving switch's tubing connects gets obstructed by carbon , if you ream out the port on the induced draft assembly it will allow the induced drafts switch to sense the draft motor is operational, this port needs to be reamed annually to avoid this.

Hello, it sounds like the pressure switch is not closing on your furnace and remaining open, reasons for this could be a blocked flue pipe, the tubing going from the inducer motor to pressure switch could be blocked, loose, or have condensation in it, or the switch itself is bad. U can check the tubing by taking it off blowing some air through it and making sure no condensation is in the tubing, then reinstall it. If everything checks out good then the pressure switch is bad and must be replaced.
