The flame sensor — also called a flame rod — monitors burner ignition by detecting microamp current through the flame. When it degrades with oxidation or carbon buildup, the control board can no longer confirm a live flame and shuts down the gas valve as a safety measure. The telltale symptom is a furnace or packaged unit that lights, runs for 5 to 8 seconds, then locks out — repeating this cycle until a fault code appears. Replacing the flame sensor is one of the most cost-effective furnace repairs available.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM flame rod sensor | Part No. LH33WZ009A | Factory-matched microamp signal range | Corrosion-resistant rod construction | Direct plug-in connector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e The OEM LH33WZ009A is manufactured to Carrier's exact rod geometry and insulator spec. Off-brand sensors may produce inconsistent microamp readings, causing nuisance lockouts even after installation — OEM eliminates that risk entirely.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Turn off power and gas before servicing.
