Ensure your high-efficiency gas furnace operates safely and efficiently with this premium 2-stage air pressure switch. As a vital air-proving component, this switch monitors the vacuum pressure generated by the draft inducer motor to verify proper venting and airflow before allowing the ignition process to begin. This dual-stage switch is specifically designed for multi-stage heating systems, featuring precise set points of -0.10" WC and -1.20" WC to maintain optimal performance. If your HVAC system is experiencing ignition failure, error codes related to pressure faults, or intermittent shut-offs, replacing a worn or failing pressure switch is a common and effective repair. Built for durability and precision, this component helps protect your home from potential venting hazards and ensures your furnace meets strict safety standards.
