OEM Carrier Flame Sensor for PY2PEB048115AA Gas Pack Unit

The flame sensor is the safety component that proves your Carrier PY2PEB048115AA's burners actually lit. It sits in the burner flame and uses flame rectification — a tiny DC microamp signal that passes through the ionized flame to ground — to tell the control board a real fire is present. If the board doesn't see that current within a few seconds, it shuts the gas valve to prevent raw gas from filling the heat exchanger. When the sensor gets coated in oxide or carbon, it can't read the flame: the burners light, stay on for 3–7 seconds, then go out, and the furnace tries again. That repeated light-then-drop short-cycling, often ending in a hard lockout with no heat, is the classic failing-flame-sensor symptom. This is a single-rod flame rectification sensor. A healthy sensor reads a flame-current signal in the microamp range (typically 2–6 µA DC, with most boards needing at least ~1 µA to stay in run). The rod itself is a Kanthal-style high-temperature alloy designed to survive direct flame contact for years. Why OEM matters here: generic sensors often use a thinner rod or an alloy that oxidizes faster, dropping the microamp signal below the board's threshold and causing nuisance lockouts. The OEM rod geometry and alloy are matched to your control board's exact sensing window, so it reads a clean, stable signal. Install difficulty: 1/5. Tools: 1/4" nut driver, and fine steel wool or an emery cloth if you're cleaning rather than replacing. CRITICAL SAFETY: turn off both the electrical power AND the gas supply at the furnace before removing the sensor; never work on burner components with gas live.

Compatibility

This part is compatible with Carrier model PY2PEB048115AA. 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.
