OEM Carrier Combination Gas Valve 24V 1/2" for Model PG9MAB048080ACSA

This OEM combination gas valve is the factory-specified replacement for the Carrier PG9MAB048080ACSA gas furnace, originally supplied as part number EF32CW211 (current OEM equivalent: EF660015, White Rodgers 36J24-510). The gas valve is the heart of your furnace's fuel delivery system — it receives the 24V signal from the control board, opens to allow gas flow to the burners, and closes instantly on a call for shut-down or safety trip. When it fails, symptoms include a furnace that attempts ignition but locks out with no heat, a unit that runs the inducer but never opens gas flow, or intermittent heating with erratic flame behavior.

• Specs: 24 VAC 50/60 Hz | 1/2" inlet/outlet | Pressure regulator set to 3.5" W.C. | Single-stage | Natural gas with LP conversion kit included | White Rodgers 36J24-510 platform
• OEM vs Generic: OEM valves are factory-calibrated to exact inlet/outlet pressure specs and valve timing required by the Carrier PG9MAB048080ACSA control board. Aftermarket valves may carry wider pressure tolerances, risking nuisance lockouts, improper combustion, or failed inspections.
• Install difficulty: 3/5 — Gas valve replacement must comply with local codes and should be performed by a licensed HVAC technician. Required tools: adjustable wrench, pipe thread sealant (gas-rated), manometer for outlet pressure verification, and 1/4" nut driver for wire terminals. Always shut off gas supply and power before beginning. Leak-test all fittings with approved solution after reinstallation.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Engineered for Carrier model PG9MAB048080ACSA gas furnace. OEM part number EF32CW211 has been superseded by EF660015 — both numbers are fulfilled with the current production valve. Verify your unit's data plate gas type (natural gas or LP) and inlet pressure before ordering. Need fitment confirmation? Our HVAC parts specialists verify compatibility before you buy.
