OEM Carrier Flame Sensor for PG8UAA036111ADJA Gas Package Unit

The flame sensor is the safety device that proves the burners in your Carrier package unit actually ignited. After the hot surface igniter glows and the gas valve opens, this slender metal rod sits directly in the burner flame and produces a small DC current through flame rectification, signaling the control board that it is safe to keep gas flowing. As the rod accumulates oxide and carbon buildup, that microamp signal weakens until the board can no longer detect the flame. The hallmark symptom is short-cycling: the unit lights, burns for a few seconds, then shuts the gas valve and retries, so you feel little or no heat and the blower delivers cool air. This is a single-rod flame rectification sensor built with a stainless-steel sensing tip and a high-temperature ceramic insulator. A healthy rod generates roughly 1 to 6 microamps of DC current, while most Carrier boards need at least 0.5 to 1 microamp to keep the gas valve energized. The bracket and 1/4-inch quick-connect terminal match the factory part for a direct, no-modification fit. Why OEM matters: genuine sensors use corrosion-resistant alloys that maintain a strong, steady signal over thousands of heating cycles. Budget aftermarket rods oxidize faster and use thinner, lower-grade metal, leading to weak signals, nuisance lockouts, and repeat no-heat calls within a single season. Installation difficulty: 2 of 5. Tools: a 1/4-inch nut driver, fine steel wool or emery cloth, and ideally a multimeter set to DC microamps to verify the new reading. Safety first: shut off the gas supply and kill power at the breaker before removing the old sensor. Ships same business day from our stocked warehouse on orders before 3 PM CST.

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.
