The combination gas valve is the heart of your furnace's fuel delivery system — it regulates incoming gas pressure, controls the flow of gas to the burners, and responds to the 24V signal from the control board to open and close during each heating cycle. When this valve fails, the furnace will attempt ignition but produce no heat, or it may lock out entirely due to unproven flame. Common symptoms include a no-heat call with a working igniter, fault codes indicating gas valve failure, or a furnace that clicks and sparks but never fires.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM combination gas valve | Part No. EF33CW201 | 24V coil actuation | Factory-calibrated inlet\/outlet pressure settings | Direct drop-in replacement for Carrier LC348TM401737\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier valve manufactured to exact factory pressure tolerances.
