OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV048111ADJA
This is the factory OEM replacement gas valve kit (part number EF660015) for the Carrier GB1AAV048111ADJA gas furnace. The combination gas valve is the critical safety and flow-control component that regulates the supply of natural gas or propane to the burner assembly. It opens on a 24V signal from the control board and closes instantly when the call for heat ends or a safety lockout is triggered. When this valve fails, the furnace will typically ignite the hot surface igniter and prove flame sensor operation, but no heat is produced — resulting in a lockout fault code and a cold home.
- Specs: OEM combination gas valve | 24V coil voltage | Factory-matched inlet/outlet pipe sizing | Compatible with natural gas and LP configurations per original unit setup | Part No. EF660015
- OEM vs Generic: This is a genuine Carrier OEM valve, built to exact factory pressure regulation tolerances. Aftermarket valves frequently exhibit off-spec outlet pressure, which can cause nuisance lockouts, incomplete combustion, or unsafe burner operation — issues you won't face with a factory-matched OEM part.
- Install difficulty: 3/5 — Gas valve replacement requires shutting off the manual gas supply, relieving line pressure, and reconnecting threaded fittings with proper pipe sealant. Tools needed: adjustable wrench, pipe thread sealant (gas-rated), multimeter for coil continuity check, and leak-detection solution. A licensed HVAC technician is strongly recommended for this repair.
- Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
Compatibility: Engineered specifically for the Carrier GB1AAV048111ADJA 4-ton gas furnace. Always cross-reference the OEM part number EF660015 against the data plate and wiring diagram inside your unit's service panel before ordering. Not sure it fits?
