The flame sensor is a critical safety component: after the hot surface igniter lights the burner, the sensor's rod detects the presence of flame via electrical rectification and sends a confirmation signal to the control board. When the sensor fails — typically due to oxidation or carbon buildup on the rod — the furnace will light briefly then shut down within 5–8 seconds, triggering a lockout fault. This is one of the most common furnace no-heat calls in the field.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Specs:\u003c\/strong\u003e OEM part number 48GS400192 | 90-degree mounting bracket | Flame rod sensor (ionization\/rectification type) | Approximate dimensions: 4.9\" L × 1.75\" H | Factory direct replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is manufactured to Carrier's exact tolerances for rod length, rod angle, and connector type. Generic sensors may produce weak or inconsistent microamp readings, causing nuisance shutdowns even after installation — OEM eliminates that risk entirely.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Turn off power and gas before servicing. Tools needed: 1\/4\" hex driver or nut driver, needle-nose pliers. Disconnect the wire lead, remove the single mounting screw, swap the sensor, and reconnect. Clear any fault codes on the control board after installation.
