International Comfort Products H8DNL100L20A1 Air Pressure Switch
The reason for the existence of the air pressure switch is to determine whether or not the main blower is running properly. An air pressure switch is part of a small, but important collection of mechanisms designed to stop injuries or explosions. Some different switches are issued with a manual reset feature, by which you must manually reset it before the HVAC system will continue.
What to Look for when the HVAC Air Pressure Switch is Starting to Go
