This high-quality air pressure switch is a vital safety component for gas furnaces and HVAC systems. Specifically calibrated to a -1.60" WC (Water Column) set point, this air proving switch ensures that the inducer blower is creating sufficient vacuum pressure for safe combustion. By monitoring the venting system's integrity, it prevents the ignition sequence if blockages or mechanical failures are detected. Replacing a faulty pressure switch can resolve common furnace error codes, such as those related to ignition failure or venting issues. Designed for durability and precision, this switch is essential for maintaining the safety and performance of residential heating equipment.
