OEM Carrier Gas Valve Kit EF660015 for Model GB3AAV036050AEJA

This is the genuine OEM replacement gas valve kit (part number EF660015) for the Carrier GB3AAV036050AEJA gas furnace. The combination gas valve is the heart of the fuel delivery system — it regulates the flow of gas to the burners in response to signals from the ignition control board. When it fails, the furnace will attempt ignition but no gas will flow, resulting in a no-heat lockout condition. Common symptoms include repeated ignition attempts with no flame, fault codes indicating valve failure, or a furnace that simply produces no heat despite the inducer and igniter operating normally.

• Specs: OEM combination gas valve | Factory-matched inlet/outlet sizing | 24V coil actuation | Designed for natural gas or LP (verify configuration on data plate) | Pressure regulation factory-set to Carrier specifications
• OEM vs Generic: This is the exact factory-specified valve for the GB3AAV036050AEJA. Generic valves often deviate in pressure regulation settings and coil sensitivity, creating unsafe gas flow conditions or nuisance lockouts. Always use OEM on gas-carrying components.
• Install difficulty: 4/5 — Gas valve replacement requires shutting off the gas supply, depressurizing the line, and carefully transferring wiring connectors and gas line fittings. Tools needed: adjustable wrench, pipe thread sealant (gas-rated), multimeter, manometer for outlet pressure verification. A licensed HVAC technician is strongly recommended for this repair.
• Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our stocked warehouse.
