OEM Carrier Gas Furnace Flame Sensor Rod for PG8JAA066135ADJA

The flame sensor is the small single rod that proves your Carrier PG8JAA066135ADJA actually has fire in the burner. After the igniter lights the burners, the control board sends a tiny microamp signal through this rod; the flame completes the circuit and tells the board it is safe to keep the gas valve open. When the rod is dirty, oxidized, or cracked, the board can't sense flame and shuts the gas off within seconds — producing the classic symptom homeowners notice most: the furnace lights, runs for 3 to 7 seconds, then shuts down and tries again, cycling repeatedly before locking out with no heat. This OEM sensor uses a high-temperature Kanthal-style sensing rod on a porcelain insulator sized and positioned for the PG8 burner assembly. A healthy flame-rectification signal typically reads in the 1–6 microamp range on a meter set to DC microamps; a weak or fouled rod drops below the board's roughly 0.5–1 microamp threshold and triggers lockout. OEM placement is critical. Generic rods often sit at a slightly different angle or insertion depth, so the rod doesn't bathe fully in the flame and your microamp signal stays marginal — meaning intermittent lockouts that are maddening to diagnose. The factory porcelain also resists thermal cracking better than thin aftermarket insulators. Install difficulty: 1 of 5. Tools: 1/4" nut driver and fine emery cloth or a Scotch-Brite pad to clean the rod tip; a multimeter helps confirm the microamp reading after install. #1 safety warning: turn off the gas and kill the breaker before reaching into the burner compartment.
