OEM Carrier Gas Furnace Flame Sensor Rod for PG9YAA036080ACSS

The flame sensor is a single metal rod that sits directly in the burner flame and confirms to the control board that ignition actually occurred. Your Carrier PG9YAA036080ACSS uses flame rectification — a tiny DC micro-amp current that flows through the live flame — to prove the burners are lit before it keeps the gas valve energized. As the rod accumulates oxide and carbon, that signal fades and the board can no longer 'see' the flame. The hallmark symptom is short-cycling: the burners light for a few seconds, then drop out, and the furnace re-tries, often locking out after 3–5 failed attempts. Homeowners notice repeated igniting-then-quitting, intermittent no-heat on the coldest nights, and a flashing fault code at the control board. Specs: This is a single-rod flame-rectification sensor with a high-temperature stainless/Kanthal sensing element and a ceramic insulator rated for continuous burner exposure. A clean, healthy sensor produces roughly 1–6 microamps of DC flame current; readings below about 0.5 µA usually trip a flame-sense fault. The bracket and spade terminal match Carrier/Bryant 9-series burner geometry so the rod seats at the correct depth and angle in the flame. OEM vs Generic: Flame sensing is a precision, low-current measurement. OEM sensors use the correct alloy and rod length so the micro-amp signal lands where the board expects it. Generic rods often use lower-grade metal that oxidizes faster and sits at the wrong depth, producing weak or unstable flame current — leading to nuisance lockouts within a single season. Install: Difficulty 1/5. Tools: 1/4" nut driver, fine emery cloth, and a multimeter set to DC microamps to verify. Safety: turn the furnace off at the breaker AND shut the gas valve before removing the burner-compartment sensor. Ships same business day from our stocked warehouse on orders placed before 3 PM CST.

Compatibility

This part is compatible with Carrier model PG9YAA036080ACSS. 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.
