The inducer motor runs all the time won't shut off didn't think it was a problem since the A/C worked fine during the Summer. But now the furnace won't fire off the Red Light indicates the Pressure Switch so replaced it and still have the same problem. Now what can I check to get some heat. Pulled the hose off and made sure all ports were clear and pulled the hose off while unit was calling and Red Light went solid the blinked 3 times instead of 2 times, and when I put the hose back on the in a couple of minutes later the burner lit. When it called for hear again I had the same problem and I think it's because the inducer motor won't shut off. Why is this happening?

First we need to find out why the inducer motor is always running. Try turning the power off to the furnace and see if that resets the control board.
