OEM Carrier Furnace Flame Sensor Replacement for PG92SCS48080BAAA

The flame sensor in your Carrier PG92SCS48080BAAA furnace is a thin metal rod that sits in the burner flame and confirms the burners actually lit. It works by flame rectification, sending a tiny microamp current back to the control board. When the rod oxidizes or cracks, the board no longer 'sees' flame and shuts the gas valve within seconds as a safety measure. Homeowners notice this as short-cycling: the furnace fires, runs 3-7 seconds, then shuts off, often repeating several times before locking out and leaving you with no heat and a flashing fault code. This is a single-rod, high-temperature flame-rectification sensor with a ceramic insulator and a 1/4" quick-connect spade terminal sized for the PG92 burner assembly. A healthy sensor reads a steady flame signal in the 4-6 microamp range; below roughly 1 microamp the board will drop out. Buy the correct rod length and bend so the tip seats properly in the flame envelope. Why OEM matters here: generic sensors often use thinner or differently-alloyed rods that oxidize faster and drift out of the microamp window, causing nuisance lockouts that look like a board failure. The OEM rod is matched to your burner geometry so the tip lands in the hottest part of the flame for a strong, stable signal. Install difficulty: 1 of 5. Tools: 1/4" nut driver and a multimeter set to DC microamps. SAFETY: turn off the gas shutoff and kill the furnace breaker before removing the sensor — you are working inches from the gas burners. Light scaling can sometimes be cleaned with fine emery cloth, but a pitted rod should be replaced. Ships same business day from our stocked warehouse on orders before 3 PM CST.
