OEM Carrier Flame Sensor Replacement for PG8UAA060155ABJA Furnace

The flame sensor is the safety eye of your Carrier PG8UAA060155ABJA furnace. Once the burners ignite, this thin rod sits directly in the flame and produces a small microamp current through flame rectification, confirming to the control board that a flame is actually burning. Over time the rod becomes coated with carbon and oxide or simply corrodes, and the board can no longer detect the flame — so it closes the gas valve within a few seconds for safety. You'll see the burners light for several seconds and then drop out, the furnace short-cycling through repeated ignition attempts, and finally a lockout with no heat. This OEM flame sensor uses a high-temperature sensing rod and ceramic insulator dimensioned to sit correctly in the burner flame, delivering the stable 1–6 microamp signal the Carrier board is calibrated to read. Correct rod length, angle, and a clean surface are what keep the signal strong. Why OEM matters: generic sensors frequently use thinner rods or lower-grade ceramic that oxidize and weaken faster, and even a slightly wrong rod geometry produces a marginal signal that trips nuisance lockouts on an otherwise healthy burner. The OEM part restores the exact placement and microamp response your furnace expects. Install difficulty: 1 of 5. Tools: 1/4" nut driver, fine emery cloth for inspection, and a multimeter set to DC microamps to verify flame current. SAFETY: turn the furnace off at the breaker AND close the manual gas shutoff valve before working near the burner assembly.
