OEM Carrier Gas Valve EF32CW210 — 24V Natural Gas Replacement for PG8MAA042090AFJA

This is the OEM factory-specified combination gas valve for the Carrier PG8MAA042090AFJA gas furnace. The gas valve is the heart of your furnace's fuel delivery system — it controls the flow of natural gas from the supply line to the burners in direct response to a 24V signal from the control board. When this valve fails, your furnace will attempt ignition, the inducer will run, but no gas will flow — resulting in a lockout fault code, cold air delivery, or a complete no-heat condition. Do not operate a furnace with a suspected faulty gas valve; replace it immediately with an OEM-matched part.

• Specs: 24V coil voltage | 50/60 Hz | Natural gas | 3.5" W.C. outlet pressure (factory set) | 1/2" NPT inlet connection | Replaces OEM part numbers: EF32CW210, 36J24-618, PEF32CW210, 9D1238, 50014746
• OEM vs Generic: This is a genuine Carrier factory-authorized part. OEM gas valves are pressure-calibrated and leak-tested at the factory to exact furnace specifications. Aftermarket valves can ship with mismatched W.C. settings, causing improper combustion, nuisance lockouts, or unsafe operation — never a risk worth taking on gas-carrying components.
• Install difficulty: 3/5 — Gas valve replacement must be performed by a licensed HVAC technician. Required tools: adjustable wrench, pipe thread sealant (gas-rated), manometer for outlet pressure verification post-install, leak detection solution. Always shut off gas supply and power before beginning. Verify outlet pressure (3.5" W.C.) with a manometer after installation.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.
