This high-quality furnace pressure switch is a vital safety component designed for residential gas heating systems. As an air proving switch, its primary function is to sense the negative pressure generated by the inducer motor, ensuring that combustion gases are being properly exhausted before allowing the ignition process to begin. If your furnace is experiencing startup failures or cycling issues, this pressure sensor is a common solution for restoring reliable heating performance. Designed for compatibility with various HVAC brands including Tempstar and ICP, this switch ensures your furnace operates within safe parameters by preventing ignition if venting issues are detected.
