The flame rod uses ionization\/rectification technology to confirm burner ignition — it passes a small electrical current through the flame and verifies a return signal to the control board. If the sensor is coated, cracked, or out of position, the board will cut gas within 5–8 seconds of ignition, triggering a no-heat lockout condition. Replacing this sensor with the correct OEM part restores reliable flame confirmation and prevents nuisance lockouts.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 90-degree mounting bracket | Rod length approx. 1.6 in. | Overall dimensions approx. 4.9 in. × 1.75 in. | OEM Part # 48GS400192 | Carrier factory-genuine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM sensors are precision-formed to the exact rod geometry and alloy spec.
