The flame sensor is a critical safety component — it detects the presence of a burner flame by passing a small microamp current through the flame to ground. When the control board does not detect this signal, it cuts off gas flow as a safety measure. A dirty or failing flame sensor is one of the most common causes of a furnace that lights, runs for 5–8 seconds, and then shuts down in a lock-out condition. This OEM replacement ensures the exact microamp threshold and rod geometry specified by Carrier, restoring reliable ignition cycle performance.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM flame sensor rod with integrated wire harness | Factory-matched microamp detection threshold | Direct plug-in connector — no splicing required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e The OEM LH680014 includes the factory wire harness with the correct connector and wire gauge. Generic sensors often omit the harness or use thinner wire, introducing resistance that mimics a weak flame signal and causes nuisance lockouts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Shut off gas and power before servicing.
