OEM Carrier Pressure Switch Replacement for PG9MAB060080ABSA Furnace

The pressure switch is a safety interlock that verifies the inducer motor is moving enough combustion air—and venting flue gases properly—before the control board allows ignition in your PG9MAB060080ABSA. It senses negative pressure through a rubber hose and closes its contacts only when draft is adequate. When the switch fails, sticks open, or its hose port clogs, the board never gets the proof-of-draft signal. Homeowners notice the inducer motor spinning up and running continuously but the igniter never glowing, no heat, and often a furnace that cycles the inducer on and off as the board retries and then locks out. This OEM pressure switch is calibrated to Carrier's exact trip point—measured in inches of water column (typically around -0.50 to -0.90" W.C. depending on configuration)—with the correct normally-open contact arrangement and port fitting. Trip-point accuracy is what distinguishes a safe switch from a dangerous one. This is critical for OEM fit. Generic switches frequently ship with the wrong W.C. setpoint, so they either trip too easily (nuisance lockouts) or stay closed when draft is actually insufficient—defeating the very safety the switch exists to provide and risking flue-gas spillage. The OEM switch matches the rating stamped on your original and the factory hose routing. Install difficulty: 2/5. Tools needed: 1/4" nut driver, nut driver set, and a manometer to verify draft pressure after install. #1 safety warning: kill the 120V power at the furnace disconnect before disconnecting wiring, and never bypass or jumper a pressure switch to force the furnace to run. Ships same business day from our stocked warehouse on orders placed before 3 PM CST. Backed by a 1-year OEM warranty and 30-day hassle-free returns on uninstalled parts.

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.
