OEM Carrier Two-Stage Gas Valve & Manifold Kit 70,000 BTU — Part 327972-762 for Model PG8MAA048070AAJA

This factory-authorized OEM replacement gas valve and manifold kit (part number 327972-762) is the direct, drop-in solution for Carrier model PG8MAA048070AAJA packaged gas/electric units. As the combination gas valve and manifold assembly, this kit controls all gas flow into the burner section across both low-fire (Stage 1) and high-fire (Stage 2) operation. When this valve fails, symptoms include a complete no-heat condition, repeated ignition lockout faults, or a furnace that fires briefly and then shuts down. Do not attempt to repair a faulty gas valve — replacement is the only safe and code-compliant fix.

• Specs: 70,000 BTU input rating | 24V coil voltage | Regulated 3.5" W.C. high-fire / 1.5" W.C. low-fire | Natural gas | 1/2" inlet x 1/2" outlet | White Rodgers cross-reference: 36J55-618 | Two-stage (redundant valve) design
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part — not an aftermarket substitute. OEM valves are factory-calibrated to the exact W.C. pressure specifications of the PG8MAA048070AAJA. Off-brand valves can drift from pressure spec, causing incomplete combustion, nuisance lockouts, or unsafe CO levels.
• Install difficulty: 4/5 — Gas valve replacement must be performed by a licensed HVAC technician. Work involves shutting off and verifying gas supply, disconnecting and reconnecting gas piping, wiring the 24V harness, and verifying manifold pressure with a manometer before restoring power. Tools needed: manometer, pipe wrench, gas leak detector, multimeter.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
