The flame sensor is a critical safety component — it uses ionization\/rectification technology to detect the presence of a burner flame during each heating cycle. When the control board calls for heat and the igniter lights the burner, the flame sensor passes a small electrical current through the flame to confirm ignition. If the sensor is coated with oxidation or has failed entirely, it cannot confirm the flame, and the control board will shut off gas flow within 5–8 seconds as a safety measure — causing the furnace to lock out after 3 attempts.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 90-degree mounting angle | Includes mounting bracket | Compact rod design (~4.9\" L × 1.75\" H) | Compatible with 24V control circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part, manufactured to exact factory tolerances.
