OEM Carrier Flame Sensor 48GS400192 for Model PY2PNB024060AC

This is the factory OEM replacement flame sensor (part #48GS400192) for the Carrier PY2PNB024060AC gas furnace. The flame sensor is a critical safety component: after the burner ignites, it uses an ionization/rectification technique to detect the presence of a live flame and send a confirming electrical signal to the control board. When this sensor fails or becomes coated with oxidation, the control board cannot confirm ignition and will shut off the gas valve — typically within 5 to 8 seconds of startup — triggering a lockout fault. The result is a furnace that lights briefly and then shuts down repeatedly.

• Specs: 90-degree mounting angle | Integrated mounting bracket | Compact rod design (approx. 1.6" rod length) | Factory-matched signal output for Carrier IFC control boards
• OEM vs Generic: This OEM unit is manufactured to exact Carrier tolerances, ensuring correct signal strength and reliable flame detection. Generic sensors can produce weak or erratic signals, leading to false lockouts and premature control board wear.
• Install difficulty: 2/5 — One mounting screw, one push-on wire connector. Tools needed: 1/4" or 5/16" nut driver, fine steel wool or emery cloth (to clean rod if reusing). Always turn off power and gas before servicing. A multimeter can confirm microamp signal output after installation.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.
