The flame sensor is a safety-critical rod that detects the presence of a burner flame by passing a small microamp current through the flame to ground. When the sensor's rod becomes coated with oxidation or carbon deposits, the control board can no longer confirm combustion, triggering a safety lockout. The most common symptom is a furnace or packaged unit that successfully ignites, burns for 5–8 seconds, then shuts down — cycling repeatedly without producing sustained heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number 50HJ401431 | Factory-matched microamp sensing threshold | Rod and bracket assembly | Direct plug-in harness connector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM flame sensors are calibrated to the exact microamp detection range required by the Carrier control board. Generic sensors may read outside tolerance, causing nuisance lockouts or — more critically — delayed shutoff on flame loss.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Always shut off gas supply and 24V power at the disconnect before servicing. Tools needed: 1\/4\" hex driver or nut driver, multimeter (to verify microamp draw post-install). Take a photo of the wiring connector before removal.
