The flame sensor — also called a flame rod — is a critical safety component that detects the presence of a live burner flame during the ignition sequence. Using a rectification (ionization) technique, it passes a small electrical current through the flame and reports back to the control board that combustion is occurring. When the sensor fails or becomes coated with oxidation residue, the control board cannot confirm ignition and shuts off the gas valve within 5–8 seconds of each ignition attempt, resulting in a no-heat lockout condition. Replacing this part with the correct OEM unit restores reliable flame detection and safe furnace operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 90° mounting angle | Rod length approx. 1.6 in. | Overall dimensions approx. 4.9 in. × 1.75 in. | Carrier OEM part number 48GS400192\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM sensor manufactured to exact factory tolerances.
