OEM Carrier Flame Sensor for PG95SAS24026ABAA 95% AFUE Furnace

The flame sensor is your Carrier PG95SAS24026ABAA furnace's proof-of-flame safety device. Once the burners light, this thin metal rod sits in the flame and uses flame rectification — the flame conducts a tiny microamp DC current — to tell the control board that gas is actually burning. When the sensor is dirty or failing, the board can't 'see' the flame, so it shuts the gas valve within 2–4 seconds as a safety measure. The classic symptom is short-cycling: the burners light, run for a couple of seconds, then shut off, repeating until the furnace locks out. You get little or no heat even though ignition clearly happens. Electrically this is a single-rod rectification sensor wired to the integrated furnace control. A clean, healthy sensor passes roughly 2–6 microamps of flame current (read in DC microamps with a meter in series); anything under about 1 µA causes dropout. Oxidation and silica buildup on the rod are the usual culprits — and once the coating is baked on, the part needs replacing rather than just cleaning. Why OEM: a genuine Carrier flame rod is made from the correct high-temperature alloy and positioned at the exact insertion depth the burner box expects. Aftermarket rods are often shorter, made of lower-grade metal that oxidizes faster, or sit at the wrong angle in the flame — all of which drop your microamp signal and bring the short-cycling back within weeks. Install difficulty: 1 of 5. Tools needed: 1/4" nut driver, fine emery cloth (if you want to test-clean first), and a multimeter capable of DC microamps. #1 safety warning: SHUT OFF THE GAS and kill power at the breaker before removing the sensor from the burner assembly.

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.
