OEM Carrier Flame Sensor Rod Replacement for PG9MAA060100AAKA

The flame sensor is your furnace's safety eyes — a thin metal rod that sits directly in the burner flame and confirms ignition has actually occurred. It generates a tiny micro-amp current through flame rectification, and the control board reads that signal to keep the gas valve open. When the sensor becomes coated in carbon, corroded, or cracked, the board can no longer 'see' the flame and shuts the gas off within seconds as a safety measure. Homeowners notice this as a furnace that lights, runs for 3-7 seconds, then shuts off — over and over (short-cycling) — leaving the house cold even though the burners clearly fire. Specs: This OEM Carrier flame sensor uses a high-temp stainless/Kanthal rod rated for continuous flame exposure, with a porcelain insulator and the correct mounting bracket and spade terminal for a direct fit. A healthy sensor should read a flame current of roughly 1-6 microamps DC; replace it if cleaning no longer restores a stable signal above the board's lockout threshold (often near 0.5 µA). OEM vs Generic: Flame sensors are simple, but fit and metallurgy matter. Generic rods are often the wrong length or angle, so they sit outside the flame envelope and produce a weak, drifting signal that triggers nuisance lockouts. Cheaper alloys also oxidize faster, shortening service life. The OEM rod is matched to your burner geometry for a strong, stable flame current. Install (difficulty 1/5): One of the easiest furnace repairs. Tools: 1/4" nut driver or 5/16" socket, fine emery cloth, and a multimeter on the microamp setting to verify. Safety warning: TURN OFF power at the furnace disconnect and SHUT THE GAS before removing the burner-compartment panel. Remove one screw, unplug the connector, and reinstall.

Why Choose OEM?

OEM parts are manufactured to the exact factory specifications for your unit. Generic aftermarket alternatives may fit physically but often use lower-rated components that reduce equipment life and void manufacturer warranties. When the cost difference between OEM and generic is $10-30, the OEM part is always the smarter investment on a system worth $5,000-$15,000.
