The flame sensor is a critical safety component: once the hot surface igniter lights the burner, the flame rod detects ionization current produced by the flame and signals the control board that combustion is occurring. When this sensor fails — due to carbon buildup on the rod or a cracked ceramic insulator — the control board cannot confirm ignition and shuts off the gas valve within 5 to 8 seconds, resulting in a no-heat lockout condition. Replacing the sensor is one of the most common and cost-effective furnace repairs.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 90-degree flame sensor rod | Includes factory mounting bracket | Approx. 4.9\" L × 1.75\" H | OEM part #48GS400192 | Direct factory replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM sensor, factory-matched to the exact rod geometry and ceramic insulation grade required by the PY1PJB048115ABAA control board. Aftermarket sensors may have slightly different rod angles or higher resistance tolerances, causing nuisance lockouts even after installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Shut off gas and power before beginning. Tools needed: 1\/4\" hex driver or nut driver, flat-head screwdriver, fine steel wool or emery cloth (to clean rod if reusing).

If your furnace starts, runs for 5–8 seconds, then shuts down and attempts 2–3 more ignition cycles before locking out, a failed flame sensor is the most likely cause.
