The flame sensor — also called a flame rod — uses the principle of flame rectification to confirm that a burner flame is present after ignition. When the sensor becomes coated with oxidation or fails entirely, the control board cannot verify combustion, triggering a safety lockout. The telltale symptom: the burner ignites normally, runs for 5–8 seconds, then shuts off — often repeating two or three times before going into full lockout. Replacing this sensor restores reliable ignition and eliminates nuisance no-heat calls.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Total length 4 5\/8\" | Distance to bend 3\" | Distance to end 1 5\/8\" | Factory OEM replacement | Country of Origin: USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier OEM part, manufactured to exact factory tolerances.
