OEM Carrier Gas Valve EF680015 for Model YAC60140YAC401C

This is the OEM factory-specified combination gas valve for the Carrier YAC60140YAC401C, sold under part number EF680015. The combination 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 the gas valve fails, the result is typically a complete loss of heat, repeated ignition lockout fault codes, or a burner that lights momentarily and then goes out. Replacing the valve with an exact OEM match restores safe, factory-calibrated gas pressure and ignition sequencing.

• Specs: OEM part number EF680015 | 24V coil voltage | Combination (redundant) gas valve | Rated for natural gas; verify LP conversion compatibility with your unit's data plate
• OEM vs Generic: OEM gas valves are pressure-calibrated to factory spec at the point of manufacture. Aftermarket valves often carry wider pressure tolerances, which can cause delayed ignition, burner rollout, or nuisance lockouts — especially on high-efficiency systems.
• Install difficulty: 4/5 — Gas valve replacement involves shutting off the gas supply, depressurizing the line, disconnecting wiring harnesses and gas fittings, and verifying outlet pressure with a manometer after reinstallation. Licensed HVAC technician strongly recommended. Tools needed: manometer, pipe wrenches, pipe thread sealant (gas-rated), multimeter, and screwdrivers.
• Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.
