Ensure the safe and efficient operation of your heating system with this premium furnace air pressure switch. Designed as a critical air-proving safety component, this sensor monitors the pressure levels within the draft inducer housing to confirm proper airflow before allowing the ignition process to begin. Featuring a precise 0.47" WC (Water Column) set point and a reliable SPST (Single Pole Single Throw) configuration, this switch helps prevent the buildup of dangerous combustion gases by detecting venting obstructions or motor failures. If your HVAC unit is failing to ignite or experiencing frequent safety shut-offs, this replacement air pressure sensor is essential for restoring consistent performance and maintaining a safe environment in your home.
