The gas valve is the heart of your furnace's fuel delivery system — it receives a 24V signal from the control board and opens to allow gas flow to the burners for ignition. When this valve fails, the result is no heat: the inducer will run, the igniter will glow, but no flame will establish, triggering a lockout condition. A failed valve can also cause erratic flame behavior, delayed ignition, or a complete no-heat fault code on your control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part Number EF33CW189 | Combination gas valve | 24V coil voltage | Factory-matched pressure regulation and flow rates for the LC348TM402283\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier gas valve built to exact factory specifications.
