Ensure your high-efficiency furnace operates safely and efficiently with this premium 2-stage air pressure switch. Designed for dual-stage heating systems, this air-proving sensor monitors the vacuum pressure created by the draft inducer motor to ensure proper venting before allowing the ignition process to begin. It serves as a vital safety component, preventing the furnace from running if it detects restricted airflow, a blocked flue, or a failing inducer fan. If your heating system is experiencing startup failures, intermittent cycling, or diagnostic codes related to pressure faults, this replacement switch restores reliable communication between the inducer and the control board. Featuring dual set points calibrated at -0.10" WC and -0.85" WC, it accurately manages both low-fire and high-fire heating cycles for optimal HVAC performance.
