Ensure the safety and efficiency of your heating system with this professional-grade 0.65" WC Air Pressure Switch. Designed as an essential air-proving component for gas furnaces and HVAC units, this switch monitors the airflow generated by the draft inducer motor. It acts as a critical safety sensor, ensuring that the exhaust system is functioning correctly and the flue is clear before allowing the burner to ignite. If your furnace is experiencing ignition failures or intermittent cycling, replacing a worn-out pressure switch can restore reliable performance. Engineered for precision, this switch helps prevent the buildup of dangerous gases by detecting pressure drops or venting obstructions in residential and commercial heating equipment.
