This high-quality HVAC Air Pressure Switch is a vital safety component designed for Carrier, Bryant, and Payne gas furnaces. As an essential air-proving switch, its primary function is to monitor the pressure created by the draft inducer motor to ensure the venting system is clear and operating safely. By verifying proper airflow before allowing the ignition process to proceed, this switch prevents the furnace from operating under hazardous conditions, such as a blocked flue or a failing inducer fan. If your heating system is experiencing ignition failure or cycling issues, replacing a faulty pressure switch can restore reliable performance and ensure your home stays warm and safe during the winter months.
