This single-port air pressure switch is a vital safety component designed for modern high-efficiency HVAC furnaces. Functioning as an air-proving switch, it monitors the draft created by the inducer motor to ensure the system is venting exhaust gases safely. If the vacuum pressure reaches the calibrated set point of 0.15" WC, the switch closes to allow the ignition sequence to begin. This part is a common solution for heating systems experiencing ignition failure, intermittent operation, or 'pressure switch stuck open' error codes. Durable and precise, it ensures your residential or commercial heating equipment operates with maximum safety and efficiency by preventing the burner from firing without proper airflow.
