Product Details

Description

This premium two-stage air pressure switch is a vital safety component designed for high-efficiency gas furnaces. Functioning as an air proving switch, it monitors the vacuum pressure created by the inducer motor to ensure proper venting and combustion airflow before the ignition sequence begins. Engineered for dual-stage heating systems, it features two distinct setpoints to manage both low-fire and high-fire operations, helping to prevent the buildup of hazardous gases. If your furnace is short-cycling, failing to ignite, or triggering pressure switch fault codes, this reliable replacement sensor ensures your HVAC system operates at peak efficiency and remains compliant with safety standards.
