The combination gas valve is the critical safety and flow-control component that regulates gas pressure and delivery to the burner assembly. When the valve fails, the furnace will attempt ignition but no gas will flow — resulting in a no-heat lockout condition. You may also see the system enter a fault code after multiple failed ignition attempts as the control board detects an absent flame signal.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM combination gas valve | Factory-matched inlet\/outlet ports | 24V coil voltage | Designed for natural gas or LP (verify configuration on your unit's data plate before ordering)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This factory OEM valve is precision-calibrated to the exact manifold pressure specifications required by the Carrier LC348TM401746. Aftermarket valves may deliver inconsistent gas pressure, causing nuisance lockouts, delayed ignition, or unsafe operating conditions.
