The flame sensor is a critical safety component: its stainless steel sensing rod sits in the burner flame and passes a small microamp current back to the control board to prove combustion is occurring. When the sensor fails — typically due to oxidation or carbon buildup on the rod — the control board cannot confirm ignition and will shut off the gas valve within 5 to 8 seconds of burner startup, triggering a safety lockout. The result is a system that appears to light and then immediately shuts down, often repeating 2–3 times before locking out entirely.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part # 50HJ401431 | Stainless steel sensing probe | Alumina-coated rod | Dimensions: 2.9\" W × 4\" D × 1.75\" H | Weight: 0.09 lbs | Compatible with 24V AC control circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part, calibrated to the exact microamp threshold your control board expects. Aftermarket sensors often drift in sensitivity, causing nuisance lockouts or — worse — delayed shutoff. Always choose OEM for a safety-critical component like a flame sensor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Turn off gas and power at the breaker before beginning. Locate the flame sensor rod in the burner assembly; it is secured by a single 1\/4\" hex screw. Disconnect the wire lead, swap the sensor, and reconnect. Tools needed: 1\/4\" nut driver, needle-nose pliers, fine steel wool or emery cloth (to clean rod if reusing). Test through a full ignition cycle after reinstall.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty against defects.
