This premium air pressure switch is an essential safety component for residential and commercial HVAC systems. Functioning as an air proving switch, it monitors the draft created by the inducer motor to ensure that combustion gases are safely exhausted before the furnace is allowed to ignite. A reliable pressure switch prevents hazardous conditions by verifying proper airflow throughout the heating cycle. If your heating system is experiencing ignition failure or intermittent shut-offs, this high-precision pressure sensor is a vital replacement part to restore safe and efficient furnace performance.
