The flame sensor is a safety rod that detects the presence of a burner flame by passing a small electrical current through it. When the sensor's rod becomes coated with oxidation or carbon buildup, it can no longer reliably confirm ignition — causing the control board to cut gas flow as a safety measure. The result is a frustrating cycle: the furnace lights, runs for 5–8 seconds, then shuts off completely, often triggering a lockout fault code. Replacing the flame sensor is one of the most common and cost-effective furnace repairs.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number LH33WZ009A | Factory-matched rod diameter and mounting bracket | 1\/4\" female spade terminal | Stainless steel sensing rod with porcelain insulator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier factory part, ensuring correct rod geometry, insulator rating, and terminal fit. Generic sensors may have incorrect rod length or angle, leading to unreliable flame signal readings and repeat nuisance shutdowns.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Turn off power and gas before servicing. Tools needed: 1\/4\" or 5\/16\" hex driver, needle-nose pliers. Disconnect the single wire harness, remove the one mounting screw, swap the sensor, and reconnect. Avoid touching the rod with bare fingers — skin oils degrade the signal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
