International Comfort Products PGAD30D1K4 Air Pressure Switch
The main function of the switch is to figure out if the air blower is doing what it is supposed to do. Some different switches are designed with a reset that is manual instead of automatic, which means it will have to be manually reset before you can continue using the system. An air pressure switch is one of many other facets of the HVAC safety checks that are dedicated to keep you from harm.
Red Flags that your HVAC Air Pressure Switch is in Need of Replacement
