It senses negative pressure created by the inducer motor and closes its contacts to prove the flue is clear and the vent is unobstructed. A failed or stuck pressure switch is a leading cause of no-heat lockouts, inducer running with no ignition, and error codes pointing to a blocked vent. Replacing it restores safe, code-compliant sequencing on startup. Built to exact Carrier specifications, this switch matches the correct trip point, port configuration, and mounting for the LC348TM402290, ensuring accurate pressure sensing. Installation is straightforward — about 20 minutes: cut power, mark and disconnect the hose and wires, remove two screws, and mount the new switch. A confident DIYer can handle it; technicians will find it routine. Genuine OEM construction means reliable performance and safety.
