Check Pressure Switch The air pressure switch pictured above checks the negative pressure created by the inducer motor and tells the furnace if it is performing correctly, if not it will shut the furnace down preventing damage and unwanted carbon monoxide gasses into the house. First check the rubber hoses to make sure they are not kinked, torn or have a blockage. If so clean them out or replace them. Next it could be an electrical failure with the switch being stuck open. For an in depth guide check here on how to test a Pressure switch. Check Blower Motor
Can you hear the blower motor running? is the air blowing out hard or slow? If it is not running then you have another problem and need to call a qualified HVAC technician out to diagnose as these motors have multiple wires, a run capacitor and limit switches that need to be checked for proper operation.
