OEM Carrier Pressure Switch for PG95SAS48080BBAA Gas Furnace

The pressure switch is the safety device that confirms your inducer (draft) motor is pulling proper negative pressure through the heat exchanger and venting before the furnace is allowed to light. It physically proves the flue is clear so combustion gases can exit the home. When this switch fails or sticks, the furnace will not fire at all — you'll typically see the blower or inducer run, hear repeated clicking, get no heat, and watch the diagnostic LED flash a pressure-switch fault code before locking out. A switch that closes erratically also causes short-cycling, where the burners light for a few seconds and then drop out. This is a normally-open switch that closes on negative pressure, calibrated to a precise setpoint measured in inches of water column (typically around -0.40 to -0.65" W.C. for this PG95 single-stage cabinet). The OEM unit matches the exact trip point, hose-port size, and bracket geometry Carrier engineered for this model. OEM matters here because pressure switches are a combustion-safety component. Generic switches often ship with looser setpoint tolerances; a switch that trips too early causes nuisance no-heat calls, while one that trips too late can allow ignition during a partially blocked vent — a carbon-monoxide risk. Buy the part that's rated for your exact draft pressure. Install difficulty: 2 of 5. Tools: 1/4" nut driver, multimeter for continuity, and ideally a manometer to confirm the trip point. #1 safety warning: shut off both 120V power at the breaker and the gas supply before servicing, and inspect the vent and condensate tubing for blockage first — a clogged hose mimics a bad switch.

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.
