OEM Carrier Two-Stage Furnace Gas Valve for PG92SAS42100CAAA

The gas valve meters fuel to the burners on your Carrier PG92SAS42100CAAA furnace and is the final component the control board energizes during ignition. On a 24-volt signal, the valve opens to deliver gas at a regulated manifold pressure so the igniter can light the burners. When it fails, you get no heat at all: the igniter glows and the inducer runs, but no flame appears because no gas is delivered — or the furnace ignites on low stage and never steps to high stage. Buzzing from the valve, intermittent ignition, and lock-outs after several failed attempts are common warning signs. This is a redundant two-stage gas valve matched to the PG92 series' staged firing. It operates on 24 VAC control voltage and regulates manifold pressure to approximately 3.5" W.C. on high fire and a reduced setting on low fire (always confirm against the furnace rating plate and set with a manometer). Redundant internal valve seats provide the double shut-off required by modern safety standards. OEM is non-negotiable on the gas valve. A generic valve with a different regulator curve or staging behavior can over- or under-fire the burners, causing sooting, short-cycling on the high limit, or incomplete combustion. Genuine Carrier valves deliver the exact manifold pressures and staging logic the heat exchanger and burners were certified with. Install difficulty: 3/5. Tools needed: adjustable wrench, pipe-thread sealant rated for gas, manometer, and a multimeter. SAFETY: shut off the manual gas supply and kill the furnace breaker before removing the valve, then leak-check every joint with soap solution before relighting.

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.
