This dual air proving switch is a critical safety component designed for high-efficiency gas furnaces. By monitoring the differential pressure created by the draft inducer blower motor, this air pressure switch ensures that the combustion chamber is properly vented before allowing the ignition process to begin. Featuring precise setpoints of 1.60" WC and 0.76" WC, it detects whether the airflow is sufficient to safely exhaust flue gases. If the pressure falls outside of the designated range, the switch acts as a failsafe, preventing the burner from firing under hazardous conditions. This replacement part is essential for restoring reliable heating performance and ensuring the overall safety of your residential HVAC system.
