It monitors negative pressure created by the inducer motor and allows the ignition sequence to proceed only when venting airflow is correct, guarding against blocked flues and unsafe combustion. A failed switch typically leaves the inducer running while the furnace never lights, usually accompanied by a pressure-switch fault code at the control board. This genuine Carrier switch is calibrated to the exact factory trip point and retains the original hose connection and spade terminals for a true plug-in replacement. Installation is easy: cut power, pull the sensing hose, disconnect the two terminals, unscrew the switch from its bracket, and reverse with the new unit—about 15 minutes. Check the hose for soot, moisture, or kinks while you have it off. This part is compatible with Carrier model GB3AAV036035AAJA.
