OEM Carrier Combination Gas Valve EF33CW189 for Model LC348TM402283

This is the factory OEM replacement combination gas valve for the Carrier LC348TM402283 furnace. 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.
