OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV042091AEJA

This is the factory-specified OEM replacement gas valve kit (part number EF660015) for the Carrier GB1AAV042091AEJA gas furnace. The combination gas valve is the critical component that controls the flow of natural gas or propane into the burner assembly. It receives a 24V signal from the control board and opens to allow gas flow during a heating call. When the gas valve fails, the furnace will attempt ignition, the igniter will glow, but no gas will flow — resulting in a lockout condition and a complete loss of heat. Additional symptoms include error codes indicating failed ignition attempts, a faint clicking or buzzing from the valve area, or gas odor without ignition.

• OEM vs Generic: This is a genuine OEM Carrier valve engineered to exact factory tolerances for inlet/outlet pressure, flow rate, and coil response time. Aftermarket valves can introduce unsafe pressure deviations and may void manufacturer warranties or fail safety inspections.

Tools needed: adjustable wrench, pipe thread sealant, manometer (to verify outlet pressure), multimeter, and screwdrivers. We strongly recommend a licensed HVAC technician for this repair.
