OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV048111ABJA

This is the OEM factory-specified gas valve kit (part number EF660015) for the Carrier GB1AAV048111ABJA gas furnace. The combination gas valve is the critical component that controls the flow of gas to the burner assembly. It receives a 24V signal from the control board and opens to allow gas flow during the ignition sequence. When this valve fails, the furnace will complete its pre-ignition checks — inducer starts, pressure switches close, igniter glows — but no gas will flow, resulting in a lockout fault code. Common symptoms include no heat, repeated ignition attempts with immediate lockout, or a gas valve fault indicated on the control board LED.

• Specs: Combination gas valve | 24V coil voltage | Factory-matched inlet/outlet sizing | Includes all mounting hardware and fittings per OEM kit specification
• OEM vs Generic: This OEM kit is manufactured to exact Carrier factory tolerances for gas flow rate, valve seat sealing, and pressure regulation. Aftermarket valves often carry wider pressure tolerances that can cause erratic burner performance, nuisance lockouts, or unsafe operating conditions — always use OEM on gas-carrying components.
• Install difficulty: 4/5 — Gas valve replacement must comply with local codes and may require a licensed technician. Tools needed: adjustable wrenches, pipe thread sealant, manometer for gas pressure verification, and a combustible gas leak detector. Always shut off the manual gas supply and disconnect power before beginning work.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
