The flame sensor is a critical safety component: after the igniter lights the burner, this rod uses ionization\/rectification to confirm a live flame is present. If it cannot detect the flame — due to carbon buildup or a failed rod — the control board cuts gas within 5–8 seconds as a safety lockout, leaving your home without heat. Replacing a contaminated or failed sensor is one of the most common and cost-effective furnace repairs available.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Specs:\u003c\/strong\u003e OEM Part #48GS400192 | 90° mounting bracket | Flame rod construction | Approx. 4.9\" L × 1.75\" H | Factory-matched electrical characteristics for accurate flame signal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM sensor built to exact factory tolerances.
