OEM Carrier Two-Stage Gas Valve & Manifold Kit 70,000 BTU for Model PG8MAA036070AAJA

This is the factory OEM two-stage combination gas valve and manifold kit (part 327972-762) for the Carrier PG8MAA036070AAJA packaged gas/electric unit. The gas valve is the heart of the heating section — it meters and regulates natural gas flow to the burners across two firing stages (low fire and high fire), working in concert with the integrated manifold to ensure precise, efficient combustion. When this valve fails, common symptoms include a complete no-heat condition, the furnace locking out after ignition attempts with no flame establishment, the inducer running but burners never lighting, or a soft lockout code on the control board pointing to gas valve circuit failure. The White Rodgers 36J55-618 valve assembly included in this kit is the exact factory-specified component — not an aftermarket substitute.

• Specs: 70,000 BTU input | Two-stage operation (low & high fire) | 24VAC coil voltage | Regulated output: 3.5" W.C. high / 1.5" W.C. low | Natural gas | 1/2" inlet/outlet | Includes manifold assembly | OEM part number: 327972-762 | Cross-reference: White Rodgers 36J55-618
• OEM vs Generic: This is a genuine Carrier Factory Authorized Parts (FAP) assembly with factory-matched pressure regulation tolerances. Aftermarket gas valves frequently exhibit improper regulation pressures that cause nuisance lockouts, incomplete combustion, or carbon monoxide risk — OEM is strongly recommended for any gas-carrying component.
• Install difficulty: 4/5 — Gas valve replacement must be performed by a licensed HVAC technician or gas fitter. Required tools: manifold pressure gauge set, leak detection solution, adjustable wrench, 1/4" nut driver, screwdrivers. Always shut off gas supply and verify zero pressure before disconnecting. Leak-test all fittings after installation. Check and document manifold pressure on both stages at startup.
• Warranty: 1-year OEM factory warranty. Ships same business day from stock.

Compatibility: Designed for the Carrier PG8MAA036070AAJA packaged gas/electric unit.
