OEM Carrier Flame Sensor (48GS400192) for Model PY2PPB060115NB

This OEM flame sensor is the factory-specified replacement for the Carrier PY2PPB060115NB gas furnace. The flame sensor — also called a flame rod — is a critical safety component that uses ionization/rectification to detect the presence of a burner flame during each heating cycle. When functioning correctly, it sends a small DC microamp signal to the control board confirming combustion. When the sensor fails or becomes coated with oxidation, the control board interprets the absence of that signal as a dangerous condition and shuts the furnace off — typically 5 to 8 seconds after ignition. The result: a furnace that lights briefly, then clicks off repeatedly, leaving your home without heat.

• OEM vs Generic: This is a genuine Carrier OEM part built to exact factory tolerances for rod composition and signal conductivity. Generic sensors vary widely in rod alloy and geometry, risking nuisance lockouts or missed flame detection — a safety concern in any gas appliance.
• Install Difficulty: 2/5 — Straightforward replacement. Power down the furnace and shut off the gas supply before starting. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers.
