OEM Carrier Gas Valve EF680015 24V 1/2" for Model YAC48110YACX304AC

The Carrier EF680015 Gas Valve is the factory-specified OEM combination gas valve for the YAC48110YACX304AC packaged unit. This valve serves as the critical gateway between your gas supply and the burner assembly — receiving the 24V signal from the control board, opening to allow gas flow, and regulating outlet pressure to the burners. When it fails, the result is no heat output, repeated ignition lockouts, or a system that lights briefly then shuts down due to no confirmed gas flow. Do not attempt to repair a faulty gas valve — replacement with the correct OEM part is the only safe and code-compliant fix.

• Specs: 24VAC coil voltage | 1/2" NPT inlet & outlet | Single-stage, slow-opening | Natural Gas with LP conversion capability | Factory-set outlet pressure 3.5" W.C. | Max inlet pressure: 1/2 PSI | 0.28A draw at 50/60 Hz
• OEM vs Generic: This is a genuine Carrier OEM valve, precision-matched to the YAC48110YACX304AC's control board signal timing and pressure requirements. Aftermarket valves may present incorrect outlet pressures or coil response times, risking unsafe operation and voiding equipment warranties.
• Install difficulty: 4/5 — Gas valve replacement must be performed by a licensed HVAC technician. Tools required: gas leak detector solution or electronic sniffer, pipe wrench, 1/4" nut driver, manometer for outlet pressure verification, and thread sealant rated for gas service. Always shut off the manual gas supply and verify zero pressure before disconnecting the old valve.
• Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse when ordered by 3 PM local time.
