This genuine OEM Carrier pressure switch is a vital safety device that verifies proper venting and combustion airflow before your furnace is allowed to ignite. It monitors the negative pressure generated by the inducer motor and closes its contacts only when airflow is correct, safely preventing operation if the vent is blocked or the inducer fails. This switch is a direct-fit replacement calibrated specifically for Carrier model CP48P448P406011CP, clearing nuisance lockouts, failure-to-ignite codes, and pressure-related fault conditions. Installation is rated easy to moderate: disconnect power, remove the sensing tube and wire terminals, fit the new switch, and reconnect everything. Because the trip point is factory-set to your unit's exact specification, the correct OEM switch is essential—an incorrect pressure rating can cause unsafe operation or repeating faults. Each switch is quality-tested for accurate, reliable response. Order before 3PM CST and your pressure switch ships same-day, so you can quickly restore safe, consistent heating. Choose genuine Carrier OEM parts for the precise calibration and dependable safety protection your system was designed to rely on.
This part is compatible with Carrier model CP48P448P406011CP.
