The reason for the existence of the air pressure switch is to see if the primary blower is actually running. This switch is part of all the safety features in today's HVAC systems in place to keep you safe from injury or explosions. Some pressure switches are programmed with a manual reset, which makes you reset it by hand or else the system will cease to function.
