The flame sensor, also called a flame rod, monitors the burner to confirm ignition has occurred and signals the control board to keep the gas valve open. When the sensor fails or becomes coated with oxidation, the control board cannot confirm a stable flame and will shut off the gas valve — typically within 5 to 8 seconds of ignition — triggering a lockout fault. Replacing this sensor is one of the most common furnace\/heat pump repairs and restores reliable heating operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Carrier flame sensor assembly | 64-1\/2\" wire lead | Factory Authorized Part (FAP) | Part # LH33WZ005 | Replaces cross-reference: 300138\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part — not an aftermarket substitute.
