The flame sensor — also called a flame rod — is a critical safety component that detects the presence of a burner flame during the ignition sequence. It passes a small current through the flame and back to the control board to confirm combustion. When it fails or becomes coated with oxidation, the control board cannot verify ignition, causing the burner to light briefly and then shut down — typically within 5 to 8 seconds — triggering a safety lockout. The fix is almost always a direct flame sensor replacement.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part# 50HJ401431 | Stainless steel sensing probe with alumina-coated rod | Dimensions: approx. 2.9\"W × 4\"D × 1.75\"H | Compatible with 24V AC furnace control circuits\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. Generic sensors can vary in probe length, rod coating, and sensitivity threshold — risking nuisance lockouts or, worse, delayed shutoff.
