Product Details

Description

Ensure your residential gas furnace operates safely and efficiently with this premium air pressure switch. This air proving switch is a critical safety component designed to monitor the negative pressure created by the draft inducer motor. By verifying proper airflow and venting at a precise -0.65" WC set point, it allows the ignition sequence to proceed only when conditions are safe. If your heating system is experiencing ignition failure, frequent cycling, or pressure switch lockout codes, this replacement part is essential for restoring reliable HVAC performance. Built for durability, it helps prevent the buildup of combustion gases, protecting both your equipment and your home.
