OEM Carrier Pressure Switch for PG95XAT42060BAAA Gas Furnace

The pressure switch is a safety interlock that proves the inducer motor is actually pulling combustion air and venting flue gases before your Carrier Performance 95 is allowed to ignite. As the inducer spins up it creates a negative pressure that closes the switch contacts; only then does the control board permit the igniter and gas valve to fire. When the switch sticks, drifts out of calibration, or its hose clogs, the furnace will not start — you'll typically hear the inducer run for several seconds and then shut down, with the board throwing a pressure-switch fault and the furnace locking out. This is also one of the first things to fail after a blocked flue, a kinked sensing hose, or a clogged condensate trap on a 95% unit. This OEM switch is a normally-open diaphragm switch factory-set to the trip point this furnace requires — generally in the −0.40" to −1.10" W.C. range depending on stage — with the correct port size and hose barb to match the Carrier inducer housing. Why OEM matters here: the trip setpoint is a safety value, not a suggestion. A generic switch with the wrong setpoint can allow ignition under poor venting conditions, raising the risk of incomplete combustion and carbon monoxide, or it can nuisance-trip a perfectly healthy furnace. The OEM switch is calibrated to the airflow this exact model was designed around. Install difficulty: 2 of 5. Tools: 1/4" and 5/16" nut drivers and, ideally, an inclined or digital manometer to confirm the reading. #1 safety warning: kill power at the breaker before swapping the switch, and never jumper or bypass a pressure switch to 'get the furnace running' — it exists to prevent CO.

Why Choose OEM?

OEM parts are manufactured to the exact factory specifications for your unit. Generic aftermarket alternatives may fit physically but often use lower-rated components that reduce equipment life and void manufacturer warranties. When the cost difference between OEM and generic is $10-30, the OEM part is always the smarter investment on a system worth $5,000-$15,000.
