It monitors draft and vent flow, verifying the inducer motor has established proper combustion airflow before the ignition sequence begins. If venting is blocked or the inducer fails, the switch opens and prevents the furnace from firing, protecting against dangerous flue gas conditions. Engineered to exact factory specifications, this pressure switch matches the original tubing connection, trip point, and electrical rating for the GB1AAV036111ACJA, ensuring reliable, code-compliant operation. Installation is a moderate DIY job for the experienced homeowner: shut off power and gas, photograph wiring, transfer the hose and terminals, then mount the replacement. 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 shuts down. Replacing it with a genuine OEM part restores dependable heat and avoids guesswork.
