The flame sensor — also called a flame rod — is a safety-critical component that monitors the burner flame after ignition. A small electrical current passes through the rod; if it detects a stable flame, the gas valve stays open and heating continues. When the sensor fails or becomes coated with oxidation, the control board loses the flame signal and shuts off gas as a safety precaution — typically within 5 to 8 seconds of ignition. The result: your unit fires up briefly, then locks out on a no-flame fault code.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Carrier flame sensor assembly | 64.5\" wire lead | Flame rod construction | Factory Authorized Part (FAP) | MFG# LH33WZ005 | Country of Origin: USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part engineered to exact OEM tolerances. Generic sensors frequently use lower-grade rod alloys that oxidize faster and exhibit erratic microamp readings — causing nuisance lockouts and premature control board wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — A straightforward repair for any qualified HVAC technician. Shut off power and gas before starting. Tools needed: 1\/4\" hex driver or nut driver, needle-nose pliers, multimeter (to verify microamp output post-install). Always photograph existing wire routing before disconnecting. Verify microamp flame signal (typically 1.5–4 µA DC) after reinstall.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
