The flame sensor — also called a flame rod — monitors the burner flame by passing a small microamp current through the rod and back through the burner ground. When the sensor is coated with oxidation or fails electrically, the control board cannot confirm combustion and shuts the burner down as a safety measure. The classic symptom: your system lights, runs for 5–8 seconds, then shuts off — repeating until it goes to hard lockout.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part# LH33WZ005 | 64.5\" wire lead assembly | Factory Authorized Parts (FAP) | Carrier\/Bryant\/Payne cross-compatible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM flame rods are manufactured to exact alloy and geometry tolerances, ensuring consistent microamp output across the full burner temperature range.
