OEM Carrier Two-Stage Furnace Gas Valve for PG8MAA066135AGJA

The gas valve meters fuel to the burners in your Carrier PG8MAA066135AGJA and is one of the furnace's most safety-critical components. On a call for heat the control board sends 24 volts to the valve, which opens in a redundant two-stage sequence to deliver the correct gas flow at the right manifold pressure. When it fails you'll see the igniter glow normally but no flame appear, a furnace that lights on high fire only, or one that locks out on ignition failure. A buzzing or chattering valve, or the smell of unburned gas, points to a failing valve coil or stuck regulator. This is a two-stage 24V redundant gas valve sized for this furnace's input. It regulates manifold pressure to spec — typically near 3.5" W.C. on high fire for natural gas — and includes the dual safety solenoids that must both energize before gas flows. OEM matters because a gas valve is a life-safety device. Generic valves can have regulators that drift outside Carrier's pressure spec, causing over- or under-firing, sooting, and heat-exchanger damage, and their coils may not match the board's drive current. An exact-fit OEM valve guarantees correct staging, pressure regulation, and listed safety performance. Install difficulty: 4 of 5. Tools: adjustable wrench, pipe-thread sealant rated for gas, manometer, and a multimeter. #1 safety warning: shut off the gas supply at the manual shutoff and kill power before removal — always leak-test every joint with soap solution before relighting. If you are not comfortable with gas piping, hire a licensed technician. Ships same business day from our stocked warehouse on orders placed before 3 PM CST.

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.
