This high-quality ICP Air Pressure Switch is an essential safety component for modern HVAC systems and gas-fired furnaces. Designed as an air proving switch, it monitors the pressure differential created by the draft inducer motor to ensure proper venting of combustion gases. With a precise set point of 0.30" WC (Water Column), this switch acts as a critical fail-safe, preventing the ignition process if insufficient airflow is detected. If your heating system is experiencing ignition failure, short-cycling, or lockout codes related to pressure sensing, replacing the air pressure sensor can restore reliable performance and ensure home safety. This durable component is engineered to withstand the demanding environment of a furnace cabinet, providing accurate monitoring and long-lasting operation.
