OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV024045ACJA

This is the factory OEM gas valve kit (part number EF660015) for the Carrier GB1AAV024045ACJA gas furnace. The combination gas valve is the heart of your furnace's fuel delivery system — it receives the 24V signal from the control board and opens to allow gas flow to the burners during each heating cycle. When the valve fails, the result is typically a complete loss of heat: the inducer and igniter may operate normally, but no gas reaches the burners, triggering a lockout fault code. You may also experience intermittent heating, a furnace that lights briefly and shuts down, or a valve that fails to close fully — a serious safety concern that demands immediate replacement.

• Specs: OEM part number EF660015 | Combination gas valve | 24V coil voltage | Factory-calibrated for natural gas or LP (verify configuration on your unit's data plate) | Direct drop-in replacement for Carrier GB1AAV024045ACJA
• OEM vs Generic: This is a genuine OEM Carrier gas valve kit, engineered to exact factory tolerances for safe, reliable gas regulation. Generic valves may vary in inlet/outlet sizing, coil resistance, and pressure regulation — increasing the risk of incomplete combustion or unsafe operation. For a gas-carrying component, OEM is strongly recommended.
• Install difficulty: 4/5 — Gas valve replacement requires shutting off the gas supply, relieving line pressure, and working with threaded gas fittings. Tools needed: adjustable wrench, pipe thread sealant (approved for gas), multimeter, and manometer for pressure verification. This repair should only be performed by a licensed HVAC technician. Always leak-test all connections with an approved solution after installation.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
