OEM Carrier Gas Furnace Flame Sensor for Model PG95SAS42060BAAA

The flame sensor is the safety device that proves your Carrier PG95SAS42060BAAA furnace actually lit. After the igniter glows and the gas valve opens, this thin metal rod sits in the burner flame and generates a tiny microamp signal that tells the control board a flame is present. When it fails or becomes coated in oxidation, the board can no longer detect the flame, so it shuts the gas valve within seconds as a safety response. The classic symptom is short-cycling: the furnace lights, runs for 2–7 seconds, then drops out, often repeating several times before locking out and leaving you with no heat on the coldest mornings. This is a single-rod rectification sensor with a high-temperature ceramic insulator and a 1/4" quick-connect terminal. A healthy sensor reads roughly 1–6 microamps of flame current; below ~0.5 µA the board flags a weak flame. The rod is Kanthal-style alloy rated to withstand continuous burner-flame temperatures without scaling prematurely. Why OEM matters here: genuine Carrier sensors use the correct rod alloy, length, and insulator depth so the rod sits exactly in the flame envelope. Generic sensors often use cheaper steel that oxidizes faster, mounts the rod at the wrong depth, or uses an insulator that cracks under heat — all of which cause nuisance lockouts that look exactly like a failing board. Install difficulty: 2/5. Tools: 1/4" nut driver, fine emery cloth, and a multimeter set to DC microamps to verify flame current. Safety first: turn off the furnace at the service switch and shut the gas before removing the sensor; never clean a sensor with sandpaper, which leaves grit.

This part is compatible with Carrier model PG95SAS42060BAAA. 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.
