The flame sensor is a critical safety component: its stainless steel rod sits in the burner flame and uses microamp current rectification to confirm combustion is present. When the sensor fails — typically due to oxidation or carbon buildup on the probe — the control board cannot verify the flame, causing the unit to ignite briefly and then shut off after just 5–8 seconds, triggering a lockout. If your Carrier packaged unit lights and then immediately shuts off in a repetitive cycle, a failed flame sensor is the most common culprit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part #50HJ401431 | Stainless steel sensing rod | Alumina-coated probe | 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 OEM part is manufactured to exact Carrier factory tolerances for microamp sensitivity and probe geometry.
