The flame sensor — also called a flame rod — is a critical safety component that monitors the burner flame via electrical rectification. When the control board sends a call for heat, the sensor confirms that ignition has occurred and signals the board to keep the gas valve open. A failed or contaminated sensor cannot pass sufficient microamp current, causing the board to shut down the gas valve within 5–8 seconds of ignition — leaving you with a system that lights briefly, then shuts off on lockout.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Carrier flame sensor assembly | 64.5\" wire lead | Factory part number LH33WZ005 | Also sold as Factory Authorized Parts (FAP) designation PSE-CEA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM sensors are manufactured to exact Carrier tolerances for rod geometry, ceramic insulator grade, and wire insulation rating.
