Carrier 25HNA936A0030030 Air Pressure Switch
The main function of the switch is to sense whether the primary air circulator is circulating the air as it should. Some pressure switches may have a reset feature that is manual, which makes you reset it by hand before the entire HVAC system will continue operating again. This is one of many other facets of the HVAC safety checks that are dedicated to keep you safe.
Warning Signs that the Pressure Switch is Starting to Fail
- Your furnace can't operate at all.
- Bad volt running through the pressure switch.
- The correct temp is never fully achieved.
