The flame sensor — also called a flame rod — is a critical safety component mounted in the burner assembly. Using ionization\/rectification technology, it passes a small electrical current through the burner flame to verify ignition. If the furnace lights, runs for 5–8 seconds, then shuts down and locks out, a failed or contaminated flame sensor is the most common cause. The control board stops gas flow when it stops receiving the flame-confirmation signal, triggering a safety lockout to prevent unburned gas from accumulating.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e OEM Carrier 48GS400192 | 90-degree flame rod with factory mounting bracket included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part, manufactured to exact factory tolerances.
