The flame sensor is a critical safety component: after ignition, the control board sends a small microamp current through the sensor's stainless steel rod into the burner flame. If the board does not detect that return current within a few seconds, it cuts gas flow and locks out the system. A failed or carbon-coated flame sensor is one of the most common causes of a furnace that \u003cem\u003elights briefly, then shuts off after 5–8 seconds\u003c\/em\u003e — often followed by a lockout fault code.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part #50HJ401431 | Stainless steel sensing rod with alumina-coated probe | Dimensions approx. 2.9\" W × 4\" D × 1.75\" H | Compatible with standard 24V AC furnace control circuits | Weight: 0.09 lbs\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. OEM sensors are calibrated to the exact microamp detection threshold required by the Carrier control board. Generic sensors with off-spec rod coatings or bracket geometry can cause nuisance lockouts or, worse, unreliable flame detection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Shut off gas supply and 120V power before beginning.
