OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV036065ADJA

This is the factory-specified OEM combination gas valve kit (part number EF660015) for the Carrier GB1AAV036065ADJA gas furnace. The combination gas valve is the critical component that controls the flow of gas to the burners. It receives a 24V signal from the control board and opens to allow gas flow during each heating cycle. When the valve fails, the furnace will attempt ignition — the igniter will glow and the flame sensor will wait — but no flame will establish, resulting in repeated lockouts and a complete loss of heat. A failed gas valve may also cause delayed ignition, weak flame, or a fault code on the control board indicating no gas pressure.

• Specs: OEM combination gas valve | 24V coil voltage | Factory-matched inlet/outlet configuration | Designed for natural gas operation (confirm LP conversion requirements with your technician)
• OEM vs Generic: This is a genuine OEM Carrier part (EF660015), manufactured to exact factory tolerances for pressure regulation, valve timing, and coil resistance. Aftermarket valves may not meet the precise pressure settings required by the GB1AAV036065ADJA, risking unsafe operation or control board faults.
• Install difficulty: 4/5 — Gas valve replacement involves shutting off the gas supply, disconnecting gas lines, and reconnecting wiring harnesses. Tools needed: adjustable wrench, pipe thread sealant, multimeter, manometer for gas pressure verification. This repair should be performed by a licensed HVAC technician. Always leak-test all connections with approved solution after installation.
• Warranty: 1-year OEM factory warranty on parts. Ships same business day from our climate-controlled warehouse to protect valve seals and components.
