It monitors draft and vent flow, confirming the inducer motor has established proper combustion airflow before ignition begins. If the vent is blocked or the inducer is weak, the switch opens and stops the furnace from firing, protecting against dangerous flue gas spillage. Built to exact factory specifications, this pressure switch matches the original tubing connection, trip point, and electrical rating for the GB1AAV036111ABJA, ensuring reliable and code-compliant operation. Installation is a moderate DIY repair: shut off power and gas, photograph the wiring and hose routing, transfer the tube and electrical terminals, then mount the new switch. Most repairs take under 30 minutes with basic hand tools. A failing pressure switch commonly causes lockouts, short cycling, or a furnace that ignites then immediately shuts down. Replacing it with a genuine OEM part restores dependable heat and eliminates guesswork.
