The gas valve is the heart of your furnace's fuel delivery system — it receives the 24 VAC signal from the control board and opens to allow natural gas or propane to flow to the burners. When it fails, the most common symptoms are a complete no-heat condition, a furnace that attempts ignition but never fires, or a unit that locks out after one or more failed ignition cycles with no gas odor at the burners.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 24 VAC coil | 3\/4\" inlet x 3\/4\" outlet | 0.23A draw | 1\/2 PSI max | Single function | Side taps | Natural gas \u0026amp; LP compatible | Replaces 36C21-411 and EF26CK201\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM-matched valve built to exact factory tolerances for gas flow rate, opening speed, and pressure regulation.
