Product Details

Description

This premium furnace air pressure switch is a vital safety mechanism designed for high-efficiency heating systems. Functioning as an air-proving sensor, it monitors the draft created by the inducer motor to ensure proper venting and airflow throughout the heat exchanger. The switch features dual-point calibration at 0.17" WC and 0.55" WC, making it ideal for multi-stage HVAC units. For single-stage furnace models, the system utilizes the high-side setting for consistent operation. Replacing a faulty pressure switch is essential for resolving ignition issues, preventing system lockout, and maintaining the safe performance of your residential heating unit.
