This high-quality Switch Assembly Pressure, also known as an air proving switch, is a vital safety component for high-efficiency forced-air gas furnaces. It is designed to monitor the negative pressure generated by the draft inducer motor, ensuring that the combustion process has proper venting and that exhaust gases are being safely expelled. If the switch detects an obstruction in the flue or a failure in the blower, it will interrupt the ignition sequence to prevent hazardous conditions. This replacement part is essential for HVAC repair when your heating system fails to ignite or throws a pressure switch error code. Built for durability and precision, it helps restore reliable operation to your home's heating system.
Type: Air Pressure Switch
