The flame sensor — also called a flame rod — is a critical safety component that uses ionization\/rectification to detect whether a burner flame is present after ignition. When the sensor becomes coated with oxidation or simply fails, the furnace control board interprets the missing signal as a failed ignition, triggering a safety lockout. The telltale symptom: the furnace lights normally but shuts itself off within 5–8 seconds, then repeats the lockout cycle.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 90° mounting angle | Rod length approx. 1.6 in. | Overall dimensions approx. 4.9 in. × 1.75 in. | Single-rod flame rectification design | OEM part number 48GS400192\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part — not an aftermarket substitute.
