The gas valve is the heart of your heating system's fuel delivery — it receives a 24V signal from the control board and opens to allow precisely regulated gas flow to the burners for ignition. When it fails, common symptoms include a furnace that attempts ignition but produces no flame, repeated lockout codes, or a unit that runs the inducer and igniter but delivers no heat. A faulty gas valve can also stick partially open or closed, creating unsafe operating conditions that demand immediate replacement.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 24VAC coil voltage | 1\/2\" NPT inlet \u0026amp; outlet | Single-stage slow-opening | Natural gas with LP conversion kit included | 0.28A | 50\/60 Hz | Max inlet pressure: 1\/2 PSI | Factory set at 3.5\" W.C.
