OEM Carrier Gas Furnace Flame Sensor Rod for PG9MAB060100ABSA

The flame sensor is the safety device that confirms your Carrier PG9MAB060100ABSA furnace actually ignited. After the burners light, this thin metal rod sits in the flame and uses flame rectification to send a tiny microamp current back to the control board. If the board doesn't 'see' that current, it assumes there is no flame, closes the gas valve, and tries again — so the classic symptom of a dirty or failing flame sensor is a furnace that lights for a few seconds then shuts off, repeating two or three times before locking out (short-cycling on ignition). This is a single-rod sensor, typically Kanthal or stainless steel, that should read a healthy flame signal of roughly 1–6 microamps DC measured in series with a meter. A reading below about 0.5 µA usually means an oxidized rod. Many 'failures' are simply a coating of carbon or silica on the rod; light cleaning with a fine abrasive pad often restores signal, but a corroded or cracked rod must be replaced. Why OEM matters here: the rod length, bend, and insulator position must place the tip in the correct part of the flame envelope. Generic sensors with the wrong geometry or an inferior alloy oxidize faster and drift out of the microamp range, returning the same nuisance lockouts you are trying to fix. Install difficulty: 1 of 5. Tools: 1/4" nut driver and a multimeter capable of reading microamps. SAFETY: shut off the gas and turn off power at the breaker before removing the sensor; the rod sits directly in the burner path and will be hot after a cycle.

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.
