The gas valve is the heart of your furnace's fuel delivery system — it regulates and controls the flow of gas to the burners in response to signals from the control board. When it fails, the result is no heat: the inducer and igniter may cycle normally, but without gas flow, the burners never light and the system locks out. A faulty gas valve can also cause intermittent heating, delayed ignition, or a furnace that lights briefly then shuts off.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM combination gas valve | Part No. EF33CW189 | Factory-matched pressure settings | 24V coil operation | Compatible with natural gas configurations — verify fuel type on unit data plate before ordering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier part built to exact factory pressure tolerances and flow rates.
