The flame sensor — also called a flame rod — is a critical safety component that detects whether a burner flame is present after ignition. Using ionization\/rectification technology, it passes a small electrical current through the flame; if no valid signal is returned to the control board within a few seconds, the board shuts off the gas valve and locks out, preventing unburned gas from accumulating. The most common symptom of a failed or fouled flame sensor is a furnace that lights, runs for 5–8 seconds, then shuts off — often repeating 2–3 times before going into lockout mode.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 90° angled mounting bracket | OEM rod length approx. 1.6\" | Overall dimensions approx. 4.9\" × 1.75\" | Includes mounting hardware | 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 part — not an aftermarket substitute. OEM sensors are factory-calibrated to the exact microamp threshold your control board expects. Generic sensors can read inconsistently, causing nuisance lockouts or masking real safety faults.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Turn off power and gas before starting. Tools needed: 1\/4\" or 5\/16\" nut driver, fine steel wool or emery cloth (to clean rod if re-using), multimeter (to verify microamp draw after install). Disconnect the single wire connector, remove the mounting screw, swap the sensor, and reconnect. Always test for proper flame signal after reinstall.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Backed by a 1-year OEM manufacturer warranty against defects.
