OEM Carrier Flame Sensor Rod Replacement for PG8DAA036070AAJA

The flame sensor is a single metal rod that sits directly in the burner flame and proves to the control board that the burners actually lit. It works by flame rectification — the flame conducts a tiny microamp current from the rod to ground, telling the board it's safe to keep the gas valve open. On your Carrier PG8DAA036070AAJA, when the rod becomes coated with oxidation or carbon, that current drops and the board can no longer 'see' the flame. The classic symptom is short-cycling: the burners light for 3–7 seconds, then shut off, and the cycle repeats — often called a flame-loss lockout. You get heat in brief bursts but never a full, satisfying run. This is an OEM flame sensor rod with the correct ceramic insulator, rod length, and spade-connector orientation for the PG8 packaged platform. Position is everything: the rod must sit inside the flame envelope to read a healthy 2–6 microamps DC. A reading below roughly 1.0 µA usually means the rod is fouled or out of position. The ceramic base is rated for continuous high-temperature exposure without cracking or shorting to the burner assembly. Why OEM matters: a flame sensor is a safety device, not just a sensor. Generic rods often use thinner Kanthal wire or lower-grade ceramic that degrades and cracks faster, leading to repeat intermittent lockouts and false flame-loss faults. An OEM rod holds its position and microamp signal across thousands of cycles, keeping the safety circuit reliable. Install difficulty: 1/5. Tools: 1/4" nut driver, fine steel wool or emery cloth, multimeter set to DC microamps. SAFETY: shut off the gas and kill the electrical disconnect before removing the sensor — the rod sits inches from a live burner.
