The flame sensor is a critical safety component — it uses a small electrical current passed through a stainless steel sensing rod to confirm the presence of a burner flame after ignition. When the sensor rod becomes coated with oxidation or carbon buildup, its microamp signal drops below the control board's threshold, triggering a safety lockout. The telltale symptom is a burner that lights normally but shuts off within 5–8 seconds, repeating 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 for corrosion resistance | Dimensions: approx. 2.9\" W × 4\" D × 1.75\" H | Compatible with standard 24V AC control circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM sensor, calibrated to exact factory microamp specifications. Generic aftermarket sensors can have wider tolerance bands, causing nuisance lockouts or — worse — delayed shutoff responses. OEM is always the recommended choice for safety-critical combustion components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Straightforward single-screw mount replacement. Tools needed: 1\/4\" hex driver or nut driver, needle-nose pliers. Always shut off gas supply and 24V power before servicing. Lightly sand the sensing rod with fine steel wool if reinstalling an old sensor; replace entirely if microamp reading is below 2µA.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty \u0026amp; Shipping:\u003c\/strong\u003e 1-year OEM manufacturer warranty.
