OEM Carrier Flame Sensor Rod for PG8UAA060135AAJA Gas Furnace

The flame sensor is a single stainless rod that sits in the burner flame and proves combustion through flame rectification — it lets a tiny microamp current pass through the flame to the burner ground. The control board reads that current and, if it doesn't see it within a few seconds of the gas valve opening, it shuts the gas off as a safety. When the rod is coated with oxide or carbon, that signal collapses: the furnace lights, burns for 3 to 5 seconds, then shuts down — and tries again and again until it locks out with no heat. This short flame-then-drop cycling is the textbook bad-flame-sensor symptom. Electrically the rod produces a small DC flame current, typically in the 1 to 6 microamp range, while most Carrier boards need at least roughly 0.5 to 1 µA to keep the valve open. The genuine sensor uses the correct rod alloy, length, and porcelain insulator so the tip lands in the right part of the flame for a strong, stable signal. OEM matters because a generic rod made of the wrong alloy oxidizes faster and reads a weaker microamp signal — so you're back to nuisance lockouts in a season or two. The exact rod geometry also keeps the sensor from grounding out against the burner. Install difficulty: 1 of 5 — one of the easiest furnace repairs. Tools: a 1/4" nut driver and, if you're testing, a multimeter set to DC microamps. SAFETY: shut off the gas and the furnace breaker before removing the sensor, and never bend the rod to reposition it. Ships same business day from our stocked warehouse on orders before 3 PM CST.
