OEM Carrier Flame Sensor for PY3PNA060130NB Gas Package Unit

The flame sensor confirms that the burner actually lit on your Carrier PY3PNA060130NB packaged gas/electric unit. It is a single rod that sits in the flame and detects the small rectified microamp current a genuine flame produces — it makes no spark and no heat of its own. If the control board never sees that current, it closes the gas valve as a safety measure. The telltale symptom is a furnace that ignites for a few seconds, then shuts down, retries, and after several cycles drops into a hard lockout with no heat; the blower may keep running while the supply air stays cold. The overwhelming majority of failures are nothing more than carbon and oxide film on the rod, though a cracked insulator or worn rod fails for good. This OEM sensor uses a stainless/Kanthal rod with a high-temperature ceramic insulator, sized and bent so the tip sits fully within the burner flame. Flame rectification normally yields a 1–6 µA DC signal; once it falls under roughly 0.5–1 µA the board reports flame loss. Because the part depends on signal strength rather than resistance heating like a thermocouple, correct rod length and position are critical — and this sensor matches the board's flame-sense threshold. Generic sensors often have the wrong length or bend, leaving the tip at the edge of the flame where it reads weak and triggers nuisance lockouts, and their cheaper alloys oxidize faster. The OEM rod is shaped for full flame immersion and a strong, stable signal. Install difficulty: 1/5. Tools: a 1/4" nut driver, fine steel wool or emery cloth, and a multimeter that reads DC microamps. #1 SAFETY WARNING: shut off the gas supply and kill furnace power before reaching into the burner area to remove the sensor.

Compatibility

This part is compatible with Carrier model PY3PNA060130NB. 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.
