The combination gas valve is the heart of your furnace's fuel delivery system — it regulates and controls the flow of natural gas or propane from the supply line to the burner assembly. When the gas valve fails, the furnace will attempt ignition but produce no flame, lock out on a safety fault, or fail to heat entirely. Common symptoms include a hot surface igniter that glows but no burner ignition, error codes indicating valve failure, or a furnace that runs the inducer and igniter cycle repeatedly without lighting.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM combination gas valve | Part No. EF660015 | Factory-matched pressure and flow ratings | Compatible with natural gas and LP configurations per unit data plate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM valve — factory-tested to exact pressure tolerances and safety certifications.
