The flame sensor — also called a flame rod — is a critical safety component mounted in the burner assembly. It passes a small microamp current through the flame to confirm combustion is present. When the sensor fails or its probe becomes coated with oxidation, the control board cannot verify a flame, triggering a safety lockout. The most common symptom: the burner ignites normally, runs for 5–8 seconds, then shuts off and the system goes into lockout — repeatedly.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part #50HJ401431 | Stainless steel sensing probe | Alumina-coated rod | Compact form factor: 2.9\" W × 4\" D × 1.75\" H | 24V AC control circuit compatible\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 for microamp signal sensitivity.
