Product Details

Description

This premium air pressure switch is an essential safety component for modern HVAC systems and gas furnaces. Functioning as an air proving sensor, it monitors the pressure differential created by the draft inducer motor to ensure proper venting before the ignition process begins. By detecting precise pressure levels, this switch prevents the furnace from operating under unsafe conditions, such as blocked flues or motor failure. If your heating system is cycling incorrectly or failing to ignite, replacing a worn or faulty pressure switch can restore safe and efficient operation. Designed for high reliability, this dual-setting switch provides accurate sensing for residential and commercial heating equipment.
