OEM Carrier Flame Sensor 48GS400192 for Model PY3PPA036060NB

This OEM flame sensor (part number 48GS400192) is the factory-specified replacement for the Carrier PY3PPA036060NB packaged gas unit. The flame sensor — also called a flame rod — is a safety component that detects the presence of a burner flame via electrical current rectification. When the sensor's rod becomes coated with oxidation or carbon deposits, it can no longer pass sufficient microamp current to prove flame to the control board, causing the furnace to light briefly and then shut down in a lockout condition within 5 to 8 seconds of ignition. Replacing the flame sensor is one of the most common and cost-effective furnace repairs.
