OEM Carrier Flame Sensor for PY3PEA048130NA Gas Pack Furnace

The flame sensor is the safety device that proves your Carrier PY3PEA048130NA's burners actually lit. After the igniter fires and the gas valve opens, this metal rod sits in the flame and uses flame rectification — a tiny microamp DC current that flows only when real flame surrounds the rod — to tell the control board it is safe to keep gas flowing. When the sensor gets coated or weak, the board can't confirm flame and shuts the gas off as a safety response. The classic symptom: the furnace lights for 3–7 seconds, then the burners snuff out, and after a few retries the unit locks out. Homeowners notice short-cycling heat, intermittent no-heat, or warm air that quits almost as soon as it starts. This is a single-rod flame-sensing electrode, typically a Kanthal/stainless rod on a ceramic insulator. It is not measured in ohms — it's tested in microamps. A clean OEM sensor on this furnace should read roughly 2–6 µA of flame current; anything under about 1 µA causes dropout. Oxide buildup on the rod is the #1 cause of low signal. OEM matters because rod length, alloy, and insulator placement set exactly where the rod sits in the flame envelope. Generic sensors with the wrong geometry or lower-grade alloys sit in a cooler part of the flame or oxidize faster, producing marginal microamp readings and recurring nuisance lockouts. The correct OEM rod restores a strong, stable signal. Install difficulty: 1/5. Tools: 1/4" nut driver and fine emery cloth or a Scotch-Brite pad (for the connector, not the new rod). #1 safety warning: turn off the gas supply and furnace power before removing the sensor, and avoid touching the new rod's ceramic insulator with bare hands.

Compatibility

This part is compatible with Carrier model PY3PEA048130NA. 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.

Shipping & Returns

Same-day shipping on orders before 3 PM CST. Standard delivery 2-5 business days, express options available at checkout. 30-day hassle-free returns on uninstalled parts — free return shipping included. 1-year OEM factory warranty coverage.
