OEM Carrier Pressure Switch for Model PG96VAT48080BAAA Furnace

The pressure switch is a critical safety device in your Carrier PG96VAT48080BAAA furnace. It confirms that the inducer motor is pulling proper draft and that the venting is clear before the control board allows the igniter and gas valve to energize. If it doesn't close, ignition is blocked. The telltale symptoms of a failing switch are a furnace where the inducer spins up and then nothing happens, no ignition and no heat, or a unit that runs briefly then drops out on a vent-safety fault. A blocked vent, water in the tubing, or a tired diaphragm all produce the same no-heat lockout. This OEM normally-open pressure switch is calibrated to a specific trip point measured in inches of water column (typically in the -0.50 to -0.90" W.C. range for this 96% condensing platform) and matched to the PG96VAT inducer's draft. Trip-point accuracy is the whole point of the part, so the OEM calibration must match your furnace. Why OEM: generic pressure switches frequently ship with wider trip-point tolerances, which either nuisance-trip on a healthy furnace or, worse, fail to catch a genuine venting problem — defeating the safety the switch exists to provide. The Carrier OEM switch holds the correct setpoint. Install difficulty: 2 of 5. Tools: 1/4" nut driver, and a manometer to verify actual inducer draft against the switch rating. #1 SAFETY WARNING: kill the furnace breaker before working, and inspect the rubber hose for cracks or condensate — a clogged tube mimics a bad switch and must be cleared, not bypassed.
