OEM Carrier Flame Sensor Rod Replacement for PG95XAT48100CAAA

The flame sensor in your Carrier PG95XAT48100CAAA is a single metal rod that sits directly in the burner flame and confirms ignition actually happened. It works by flame rectification: the control board sends a small AC voltage down the rod and the flame conducts a tiny DC micro-amp current back to ground. No current means no proof of flame, and the board closes the gas valve within seconds. When the rod oxidizes, cracks, or its ceramic insulator carbon-tracks, the burners light and then drop out after 3-7 seconds. You'll notice the furnace short-cycling and retrying, then a hard lockout with no heat after three or four failed trials. Specs: this is an OEM stainless/Kanthal sensing rod on a high-temperature ceramic isolator, matched to the flame-rectification circuit on Carrier's PG95 control. A healthy sensor reads roughly 1-6 microamps of flame current on a meter set to DC microamps; anything under about 0.7 µA trips lockout. The rod length and bracket are dimensioned to seat correctly in this furnace's flame envelope. Why OEM matters: a flame sensor is a safety device. Generic rods often use thinner sensing material and looser insulator ceramics that carbon-track sooner and drift in micro-amp output, producing nuisance lockouts on a unit that was running fine. An OEM rod holds the signal strength the board expects. Install difficulty: 2 of 5. Tools: 1/4" nut driver, light sandpaper or a Scotch-Brite pad to clean the rod, and a multimeter that reads DC microamps to verify. #1 safety warning: shut off both power at the furnace switch/breaker AND the gas before removing the burner-compartment sensor — never service it with the gas on.

Compatibility

This part is compatible with Carrier model PG95XAT48100CAAA. 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.
