Heater is not blowing hot air out of vents

racer36 Member Posts: 1
My furnace was brand new when i bought my house a year ago. Recently it has started not blowing hot air of the vents. its more just blowing air non stop. The only thing i can find is that its an International Comfort Products? 80+ single stage gas furnace. Its an upflow. Any suggestions?

    Check thermostat isn't set to fan-on .   Most furnaces will go into a constant blower state if trouble in furnace.

    Find the shut off switch...

    Turn it off for 30 seconds, and then back on and see if it starts up correctly.
