OEM Carrier Flame Sensor for PG9MAB060080LBSA Package Furnace

The flame sensor is a single metal rod that confirms the burners actually lit on your Carrier PG9MAB060080LBSA package furnace. Using flame rectification, the control board sends a small AC signal through the flame; the ionized flame conducts a tiny DC microamp current back to the board, proving the burners are burning. A dirty or failed sensor is the #1 cause of short-cycling on heat: the burners light for 3–7 seconds, then shut off because the board never "sees" a stable flame. You'll notice the furnace lighting and dropping out over and over, often locking out after several tries and pushing lukewarm air from the registers. This is an OEM flame sensor rod with the correct ceramic insulator and mounting-bracket geometry, so the rod sits in the proper flame envelope. A healthy sensor reads roughly 1.5–6 microamps of flame current, measured in series with a meter set to DC microamps; below about 0.5 µA the board drops the flame. The rod is a high-temperature Kanthal-type alloy built to resist scaling. Flame current is tiny, so rod length, position, and insulator quality matter. A generic sensor mounted even a few millimeters off the flame, or with a leaky insulator that shorts to ground, will read low microamps and cause nuisance lockouts. The OEM rod places the sensing surface exactly where Carrier engineered it. Install difficulty: 1/5. Tools needed: 1/4" nut driver and fine emery cloth or a Scotch-Brite pad (never gritty sandpaper on the rod). Safety: turn off the gas and power before removing it, and don't touch the cleaned rod with bare fingers — oils degrade the signal.

Compatibility

This part is compatible with Carrier model PG9MAB060080LBSA. 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.
