OEM Carrier Flame Sensor 48GS400192 for Model PY3PNA036060AA

This is the OEM factory-specified flame sensor (part #48GS400192) for the Carrier PY3PNA036060AA packaged unit. The flame sensor — also called a flame rod — is a safety component that detects the presence of a burner flame and sends a small microamp signal to the control board confirming ignition. When the sensor becomes coated with oxidation or carbon deposits, its ability to conduct this signal degrades. The result is a furnace that ignites briefly, then shuts down within 5–8 seconds, often triggering a repeated lockout sequence. Replacing this sensor with the correct OEM part restores accurate flame detection and reliable heat operation.
