OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV036090AAJA

This is the OEM-specified combination gas valve kit (part number EF660015) for the Carrier GB1AAV036090AAJA gas furnace. The gas valve is the electromechanical component that controls the flow of natural gas or propane from the supply line to the burner assembly. When energized by the control board through the 24V circuit, it opens to allow gas flow during an ignition sequence. A failed gas valve is one of the most common causes of a no-heat condition — symptoms include the inducer and igniter firing normally but no burner flame establishing, repeated ignition lockouts, or a complete absence of gas at the burners despite all other components functioning correctly.

• Specs: OEM combination gas valve | 24V coil voltage | Compatible with natural gas and LP (verify manifold pressure setting) | Factory-calibrated inlet and outlet pressure ratings for the GB1AAV036090AAJA furnace
• OEM vs Generic: OEM gas valves are pressure-tested and calibrated to factory specifications, ensuring correct manifold pressure, reliable coil actuation, and safe shutoff. Generic valves can exhibit pressure drift, slow response, or inconsistent shutoff — all potentially unsafe in a gas appliance.
• Install difficulty: 4/5 — Gas valve replacement involves shutting off the gas supply, depressurizing the line, and reconnecting gas fittings with leak-tested joints. Tools needed: adjustable wrench, pipe thread sealant, manometer, multimeter, and leak detection solution. Installation should be performed by a licensed HVAC technician in accordance with local codes.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
