This premium two-stage air pressure switch is a vital safety component for modern high-efficiency gas furnaces. Designed to ensure proper combustion airflow, this air-proving switch monitors the negative pressure produced by the draft inducer motor. By verifying that the venting system is clear and the exhaust blower is functioning correctly, it allows the heating system to safely proceed to the ignition sequence. This dual-stage switch is calibrated to specific vacuum thresholds of -0.72" WC and -0.97" WC, making it essential for multi-stage furnaces that require precise airflow detection at different firing rates. Replacing a faulty or failing pressure switch can resolve common furnace issues such as ignition failure, intermittent operation, and system lockout error codes related to venting.
