The gas valve is the critical component that controls the flow of fuel from the supply line to the burner assembly. It receives a 24V signal from the control board and opens to allow gas flow during each ignition sequence. When this valve fails, the furnace will attempt ignition but produce no flame — resulting in a lockout condition and no heat. Common failure symptoms include the inducer running normally while the burner never lights, error codes indicating a gas supply fault, or a valve that sticks open or closed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number EF33CW201 | 24V coil voltage | Combination redundant gas valve | Factory-matched inlet\/outlet configuration for Carrier LC348TM401843\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM valve built to exact factory tolerances for pressure regulation, seat sealing, and coil response time.
