OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV024055AAJA

This is the factory OEM replacement gas valve kit (part number EF660015) for the Carrier GB1AAV024055AAJA gas furnace. The combination gas valve is the critical component that controls the flow of gas from your supply line to the burner assembly. It receives a 24V signal from the control board and opens in sequence with the igniter and flame sensor to deliver a safe, controlled flame. When the gas valve fails, the furnace will complete the inducer and igniter warm-up cycle but produce no heat — resulting in a no-ignition lockout, fault codes, or a completely cold system.

• Specs: OEM combination gas valve | 24V coil voltage | Factory-matched inlet/outlet pipe sizing | Designed for natural gas operation — verify LP conversion if applicable
• OEM vs Generic: This is a genuine OEM Carrier part (EF660015), manufactured to exact factory tolerances for pressure regulation, valve timing, and coil voltage draw. Aftermarket gas valves can introduce unsafe pressure variances and are not recommended for gas-train components.
• Install difficulty: 4/5 — Gas valve replacement involves working on a live gas line and should only be performed by a licensed HVAC technician. Tools needed: adjustable pipe wrenches, manometer for gas pressure verification, leak-detection solution, and a multimeter to confirm 24V signal at the valve terminals. Always shut off the gas supply and power before beginning work.
• Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier GB1AAV024055AAJA gas furnace. Always cross-reference the OEM part number EF660015 and verify inlet gas type (natural gas vs. LP) on your unit's data plate before ordering. Our fitment team is available to confirm compatibility prior to purchase — ships same business day when ordered before cutoff.
