The flame sensor is a critical safety component — its flame rod detects the presence of a burner flame by passing a small electrical current through it. If the control board does not receive confirmation of flame within a few seconds of gas valve opening, it will shut down the burner as a safety precaution. A failed or contaminated flame sensor is one of the most common causes of a furnace or packaged unit that lights briefly and then shuts off after just 5–8 seconds, often triggering a lockout fault code.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number 48GS400192 | Factory flame rod assembly | Direct drop-in fit for Carrier PY3GNA048090AB | Engineered to meet original factory electrical resistance specifications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM flame sensors are manufactured to exact factory tolerances for rod geometry and ceramic insulation quality.
