OEM Carrier Gas Valve EF33CW201 for Model LC348TM401747

This is the OEM factory-specified combination gas valve for the Carrier LC348TM401747 furnace. The gas valve is the critical component that controls the flow of gas from the supply line to the burners. It receives a 24V signal from the control board and opens to allow gas flow during the ignition sequence. When this valve fails, the furnace will complete its inducer and ignition pre-checks but produce no heat — often triggering a lockout fault code. Common symptoms include no ignition, intermittent heating, or the furnace shutting down immediately after the ignition attempt.
