Carrier 24ABA342A0030010 Air Pressure Switch
The main job of the air pressure switch is to sense if the primary blower is actually running. An air pressure switch is one of the vitally important safety devices that are created to keep everyone in the house safe. Most air pressure switches may have a reset feature that is manual, by which you must manually reset it before the HVAC system will continue.
Warning Signs that the Switch is Beginning to Fail
- The proper temperature in the house is rarely reached.
- Wrong volt range running through the switch.
- The furnace or AC refuses to operate.
