The flame sensor — also called a flame rod — is a critical combustion safety component: it detects the presence of a burner flame by passing a small microamp current through the flame to ground. When the sensor is fouled with oxidation or has failed entirely, the control board cannot confirm ignition and will lock out the gas valve, typically causing the burner to light and then shut off within 5 to 8 seconds, resulting in a no-heat call.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 50HJ401431 | Genuine Carrier factory-original replacement — not an aftermarket substitute\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e \u003cstrong\u003eStainless steel sensing probe\u003c\/strong\u003e with corrosion-resistant alumina-coated rod | Compact form factor (approx. 2.9\" W × 4\" D × 1.75\" H) | Weighs approx. 0.09 lbs for easy handling during service\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM sensors are calibrated to exact microamp detection thresholds required by the Carrier control board.
