OEM Carrier Pressure Switch for PG8MEA060110ACJA Gas Furnace

The pressure switch is a critical safety device on your Carrier PG8MEA060110ACJA package gas furnace. It confirms that the draft inducer motor is actually pulling combustion air and venting flue gases before the board allows the igniter and gas valve to energize. When the switch fails or sticks open, the furnace will not start, may short-cycle, or will flash a pressure-switch fault code and drop into lockout — meaning no heat even though the inducer spins up. A switch stuck closed is even more dangerous, because it can allow ignition without proper venting. This is a normally open, single-pole single-throw (SPST) negative-pressure switch with a factory-calibrated trip point measured in inches of water column. The exact set point is printed on the switch body and must match your furnace's specification; on this PG8M induced-draft platform it falls in the low negative range typical of single-stage units. With the inducer off you should read an open circuit, and continuity once proper draft is established — verify with a multimeter. OEM specification is essential here because the calibrated set point is a safety threshold. A generic switch with a wider tolerance or wrong pressure rating may close on insufficient draft (allowing unsafe ignition) or never close (nuisance lockouts). Genuine Carrier-spec switches hold their calibration over thousands of cycles. Install difficulty: 2 of 5. Tools: 1/4-inch and 5/16-inch nut drivers, and a multimeter for continuity testing. SAFETY: kill power at the breaker before servicing, and inspect the rubber tubing and inducer port for blockage or condensate — a clogged hose mimics a failed 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.
