International Comfort Products H9MPT075F12A1 Air Pressure Switch
The primary function of the switch is to sense whether the main blower is running. Various air pressure switches are constructed with a manual reset, which makes you reset it by hand before the entire HVAC system will continue operating again. This pressure switch is one of many other facets of the HVAC safety checks that are dedicated to keep everyone in the house safe.
