The gas valve is the critical control component that regulates natural gas or propane flow to the burner assembly. When the control board sends a 24V signal during a heating cycle, the valve opens to allow gas flow for ignition. A failed gas valve typically results in a no-heat condition — the inducer and igniter may operate normally, but the burner never lights, triggering a lockout fault code. In some cases, the valve may open intermittently, causing unreliable or delayed heating performance.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part Number EF33CW201 | Combination gas valve | 24V coil voltage | Compatible with natural gas and LP (verify configuration) | Factory-matched pressure and flow settings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the exact factory-specified valve engineered for the LC348LC400401.
