OEM Carrier Flame Sensor 48GS400192 for Model PY3PNA036060NB

This OEM flame sensor is the factory-specified replacement for the Carrier PY3PNA036060NB gas furnace. The flame sensor — also called a flame rod — uses ionization/rectification technology to detect the presence of a burner flame and send a confirmation signal to the control board. When it fails or becomes coated with oxidation, the control board cannot verify ignition and will shut the gas valve within 5–8 seconds of each ignition attempt, resulting in a no-heat lockout condition. Replacing this sensor is one of the most common and cost-effective furnace repairs.

• OEM vs Generic: This is a genuine Carrier OEM sensor matched to factory tolerances. Generic flame sensors may vary in rod length, bend angle, or connector type — mismatches cause unreliable flame detection and repeat lockouts.
