This 90-degree flame rod uses ionization\/rectification technology to confirm burner ignition during every heating cycle. When the burner fires, the flame sensor generates a small DC microamp signal that tells the control board the flame is present and safe to keep the gas valve open. A failed or contaminated sensor causes the furnace to light briefly and then shut down within 5–8 seconds — leaving your home without heat and triggering repeated ignition lockouts.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Specs:\u003c\/strong\u003e OEM part number 48GS400192 | 90-degree mounting bracket included | Flame rod length approx. 1.6 in. | Overall dimensions approx. 4.9 in. × 1.75 in. | Factory-matched microamp output tolerance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM component — not an aftermarket substitute. OEM sensors are calibrated to the exact microamp threshold the Carrier control board expects, reducing nuisance lockouts caused by off-spec generic rods.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — One mounting screw and one spade connector. Tools needed: 1\/4 in. or 5\/16 in. nut driver, fine steel wool or emery cloth (to clean rod if reusing), multimeter (to verify microamp draw post-install). Always shut off power and gas before servicing. Clean the rod surface if carbon-coated before condemning the part.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty against defects.
