OEM Carrier 2-Stage Gas Valve & Manifold Kit 70,000 BTU for Model PG8MAA024070AAJA

This OEM combination gas valve and manifold kit (part number 327972-762) is the factory-specified replacement for the Carrier PG8MAA024070AAJA packaged gas furnace. The gas valve is the heart of your furnace's heating operation — it meters natural gas flow to the burners in two stages: a reduced first stage for mild demand and a full second stage for maximum heat output. When the valve fails, symptoms include a complete no-heat lockout, the furnace igniting briefly then shutting down on gas-pressure fault, or intermittent heating caused by a stuck-open or stuck-closed valve port. This is a complete kit including the gas valve body, manifold assembly, and all hardware needed for a direct swap.

• Specs: 70,000 BTU input | 2-stage operation | 24V coil | Natural gas | Regulator factory-set to 3.5" W.C. (Hi) / 1.5" W.C. (Lo) | White Rodgers 36J55-618 valve body | Cross-ref: 92-0659
• OEM vs Generic: This is a Carrier Factory Authorized Part. OEM gas valves are calibrated to exact manifold pressure specs for your burner orifice set — off-spec pressure from a generic valve risks incomplete combustion, sooting, or nuisance lockouts. Do not substitute for a gas-side component.
• Install difficulty: 4/5 — Gas valve replacement requires shutting off the gas supply, depressurizing the line, disconnecting the wiring harness and manifold, and leak-testing all connections after installation. Tools needed: adjustable wrench, pipe thread sealant, manometer or magnehelic gauge, leak-detection solution. Licensed gas technician strongly recommended.
• Warranty: 1-year OEM factory warranty against manufacturing defects. In-stock and ships same business day from our warehouse.
