OEM Carrier Furnace Flame Sensor for PG8DAA036095ABJA Gas Pack

The flame sensor is a single metal rod that proves your burners have actually lit. On the Carrier PG8DAA036095ABJA gas pack, the control board passes a tiny current through this rod to confirm flame using flame rectification. When the rod gets coated with oxide or carbon, or the metal fatigues, the board can no longer 'see' the flame and shuts the gas valve within seconds. Homeowners notice the burners light and then go out after 2-7 seconds, the furnace short-cycles, heat becomes intermittent or stops entirely, and after several failed attempts the unit drops into a hard lockout. This is a single-rod flame rectification sensor. A healthy flame produces roughly 1-6 microamps of DC current; readings below about 0.5 µA cause the board to drop out and fault. The rod is a high-temperature stainless/Kanthal alloy rated for continuous direct flame contact, and current is verified with a meter placed in series on the microamp scale. OEM matters here because rod length, alloy, and bracket geometry place the tip in exactly the right zone of the flame envelope. Generic sensors with shorter rods or substitute alloys read lower microamp current, oxidize faster, and trigger nuisance lockouts even when the burners are firing perfectly. Install difficulty: 2/5. Tools: 1/4" nut driver, fine emery cloth or steel wool to clean the rod, and a microamp-capable multimeter. #1 safety warning: shut off the gas supply and kill power at the breaker before removing the sensor — never service it with the gas valve energized.
