The main function of this type of switch is to determine whether or not the primary air circulator is blowing air. This is one of the critical devices designed to keep you from harm. A lot of switches have a manual reset feature, which makes you reset it by hand before the HVAC system will continue.
Signals that the HVAC Air Pressure Switch is Failing
