OEM Carrier Furnace Flame Sensor for PG9MAB036060ABSA Unit

The flame sensor is a single metal rod that sits in the burner flame and proves to the control board that a flame is actually present after the gas valve opens. It works by flame rectification — the lit flame conducts a tiny microamp DC current to ground, telling the board it's safe to keep the gas on. When the sensor is coated in oxide or failing on your Carrier PG9MAB036060ABSA, the classic symptom is short-cycling on ignition: the burners light for 3–7 seconds, then the gas valve snaps shut and the furnace tries again, often locking out after three attempts. You'll feel brief warm air followed by cold, and the thermostat never satisfies. Specs: this is a single-rod silicon/Kanthal sensing electrode with a ceramic insulator and porcelain standoff matched to the PG9MAB burner geometry, so the rod sits at the correct depth and angle in the flame envelope. A healthy circuit reads roughly 1–6 microamps DC of flame current; below ~0.5 µA the board will not prove flame. Why OEM matters: a flame sensor must position the rod precisely in the flame and use the right alloy and insulator. Generic sensors with the wrong rod length, bend, or insulator can sit too low in the flame or leak current to ground, producing weak microamp readings and the same nuisance lockouts you're trying to fix. The OEM rod restores the factory flame-current signal. Install difficulty: 1/5 — the easiest furnace repair there is. Tools: 1/4" nut driver (often a single screw) and fine emery cloth to lightly clean the new rod's tip. #1 SAFETY WARNING: Turn off the gas at the shutoff valve and kill power at the breaker before reaching into the burner compartment.

Compatibility

This part is compatible with Carrier model PG9MAB036060ABSA. Always verify the part number against your unit's data plate before ordering.

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.
