OEM Carrier Flame Sensor 48GS400192 for Model PY1PEB036060AAAA

This OEM 90-degree flame sensor is the factory-specified replacement part for the Carrier PY1PEB036060AAAA gas furnace. The flame sensor is a critical safety component that uses ionization/rectification technology to detect the presence of a burner flame during each heating cycle. When the burner ignites, the flame generates a small electrical current through the sensor rod — confirming to the control board that safe combustion is occurring. If the sensor is coated with oxidation or has failed entirely, the control board cannot confirm ignition and will cut gas flow within 5–8 seconds as a safety lockout, leaving your home without heat.
