By sensing negative pressure in the vent system, it protects against blocked flues, failed inducers, and unsafe combustion, opening to shut down ignition the instant draft is lost. A failing switch commonly causes no-heat lockouts, repeated short cycling, and pressure-switch fault codes. Made to exact factory specifications, it matches the original trip pressure and hose connections of the GB1AAV024045ADJA for accurate, code-compliant operation. Installation is moderate and DIY-friendly: shut off power and gas, disconnect the rubber hose and wire terminals, replace the switch, and reconnect securely. Most homeowners complete the swap in about 30 minutes with basic hand tools. Get your furnace back to safe, dependable heating with a part engineered specifically for your Carrier model.
