The flame sensor is a critical safety component: its stainless steel rod sits directly in the burner flame and passes a small microamp current to the control board to confirm combustion. When the sensor fails — typically due to oxidation or carbon buildup on the probe — the control board cannot verify a flame is present and shuts off the gas valve within 5–8 seconds as a safety lockout. The result is a system that appears to light, then immediately shuts down and locks out, leaving occupants without heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Specs:\u003c\/strong\u003e OEM Part # 50HJ401431 | Stainless steel sensing rod | Alumina-coated probe | Dimensions: approx. 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 factory-matched OEM sensor maintains precise microamp output tolerance required by the Carrier control board.
