OEM Carrier Gas Valve 24V 1/2" Natural/LP for Model YAC48110YACX404AC

This OEM combination gas valve is the factory-specified replacement for the Carrier YAC48110YACX404AC packaged unit. The gas valve is the critical component that controls gas flow from the supply line to the burner assembly. When it receives a 24V signal from the integrated furnace control board after the inducer and igniter have proven, it opens to allow gas flow for combustion. A failed gas valve typically results in a complete no-heat condition — the inducer starts, the igniter glows, but no flame is established, triggering a safety lockout. Other symptoms include intermittent heating, delayed ignition, or a fault code indicating a gas valve or flame failure.

• OEM vs Generic: This is the genuine OEM part (EF680015) engineered specifically for Carrier.

Tools required: adjustable wrench, pipe thread sealant (gas-rated), manometer for outlet pressure verification, multimeter for coil resistance check. Always shut off gas supply and verify zero pressure before disconnecting fittings. Leak-test all connections with approved solution after installation.
