The flame sensor — also called a flame rod — monitors the burner to confirm ignition has occurred. It passes a small electrical current through the burner flame; if it cannot detect the flame within a few seconds, the control board cuts off gas flow as a safety measure. A failed or contaminated flame sensor is one of the most common reasons a furnace or packaged unit will light briefly and then shut off, typically within 5–8 seconds, leading to a no-heat lockout condition.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Carrier flame sensor assembly | Part# LH33WZ005 | 64½\" wire lead | Factory Authorized Part | Genuine Carrier Corporation component\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM sensor is manufactured to exact Carrier factory tolerances for microamp signal output and rod geometry. Aftermarket sensors can produce inconsistent readings, causing nuisance shutdowns or false lockouts — especially in colder weather when reliable ignition detection is critical.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Turn off power and gas before servicing. Tools needed: ¼\" hex driver or 5\/16\" nut driver, needle-nose pliers, and optionally a multimeter to confirm microamp output (typically 1–4 µA). Lightly sand the sensor rod with fine steel wool if replacing due to oxidation buildup. Always confirm polarity of the wire connector before reconnecting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
