OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV024035AAJA

This is the factory OEM replacement gas valve kit (part number EF660015) designed specifically for the Carrier GB1AAV024035AAJA gas furnace. The combination gas valve is the critical component that controls the flow of natural gas or propane to the burner assembly. It responds to 24V signals from the control board, opening during the heating cycle and closing the moment the thermostat is satisfied or a safety lockout is triggered. When this valve fails, the furnace will either produce no heat at all, short-cycle before reaching temperature, or trigger a fault code indicating a gas supply or ignition failure. In some cases, a faulty valve may allow intermittent heating that becomes progressively worse over time.

• Specs: OEM part number EF660015 | 24V coil operation | Combination gas valve (manual shutoff + pressure regulator + automatic operator) | Compatible with natural gas and LP configurations per unit data plate
• OEM vs Generic: This is the factory-specified OEM valve — precision-calibrated to the exact inlet/outlet pressure and flow rate required by the Carrier GB1AAV024035AAJA. Aftermarket valves may not match the factory pressure drop specifications, leading to improper combustion, nuisance lockouts, or voided equipment warranties.
• Install difficulty: 4/5 — Gas valve replacement requires shutting off the gas supply, disconnecting wiring harnesses, and re-sealing all gas fittings. Tools needed: adjustable wrench, pipe thread sealant (gas-rated), multimeter, and a manometer for outlet pressure verification. This repair should be performed by a licensed HVAC technician or qualified professional in accordance with local codes.
