This Nordyne Air Pressure Switch is a vital safety component for residential HVAC systems. Calibrated to a precise -1.20" WC setpoint, this air proving switch monitors the draft inducer motor to ensure proper venting of combustion gases before allowing the furnace to ignite. It prevents hazardous operation by shutting down the system if insufficient airflow is detected. Ideal for repairing furnaces that fail to stay lit or won't start, this high-quality pressure sensor provides a reliable solution for maintaining heating efficiency and home safety.
