OEM Carrier Flame Sensor (48GS400192) for Model PY3PEA036060AA
This is the genuine OEM Carrier flame sensor, part number 48GS400192, factory-specified for the Carrier PY3PEA036060AA gas furnace. The flame sensor is a critical safety component — it uses electrical ionization to detect whether a burner flame is present after ignition. When it fails or becomes coated with oxidation buildup, the furnace control board cannot confirm combustion and will shut down the gas valve within 5–8 seconds as a safety precaution, resulting in a lockout fault. The fix is almost always a simple cleaning or direct replacement of this sensor rod.
