OEM Carrier Flame Sensor 48GS400192 for Model PY1PEB048115NBAA

This is the genuine OEM flame sensor (part #48GS400192) factory-specified for the Carrier PY1PEB048115NBAA gas furnace. The flame sensor — also called a flame rod — is a critical safety component mounted in the burner assembly. It detects the presence of an active flame via an ionization current and continuously signals the control board to keep the gas valve open. When the sensor becomes coated with oxidation or fails entirely, the furnace will light briefly, then shut off within 5–8 seconds, triggering repeated lockout cycles and leaving your home without heat.
