OEM Carrier Gas Valve EF33CW201 for Model LC348TM402772

This is the genuine OEM combination gas valve for the Carrier LC348TM402772 furnace. The gas valve is the critical component that controls the flow of gas to the burners in response to signals from the control board. When this valve fails, the furnace will complete its ignition sequence — the inducer starts, the igniter glows — but no gas reaches the burners, resulting in a lockout condition and no heat. A faulty gas valve may also cause intermittent heating, delayed ignition, or a soft lockout fault code on the control board.
