OEM Carrier Gas Furnace Flame Sensor Rod for PG92SCS48100CAAA

The flame sensor is a single metal rod that sits in the burner flame and confirms to the control board that gas is actually burning. It works by flame rectification — the lit flame conducts a tiny microamp current that tells the board it's safe to keep the gas valve open. In your Carrier PG92SCS48100CAAA, when this rod gets coated with oxide or fails, the classic symptom is short-cycling: the burners ignite, stay lit for 3–7 seconds, then shut off as the board fails to prove flame, repeating until lockout. Homeowners notice the furnace lighting and quitting over and over, then going cold. This OEM flame sensor rod has the correct length, bend angle, and porcelain insulator to position the tip properly in the flame envelope of this furnace's burners — placement that directly determines the strength of the microamp signal. A healthy circuit typically reads 1–6 microamps DC in series; below ~0.5 µA the board drops the gas valve. Why OEM matters: a generic rod with the wrong tip geometry or a thinner insulator sits in a weaker part of the flame or degrades faster, producing borderline signals that cause intermittent, hard-to-diagnose lockouts. The OEM rod's alloy and dimensions match the factory flame-rectification target so the signal stays well above the dropout threshold. Install difficulty: 1/5. Tools: 1/4" nut driver and fine emery cloth if you also clean the burner area. SAFETY: shut off the gas valve and kill the furnace breaker before reaching into the burner compartment. Handle the rod by the bracket, not the porcelain. Ships same business day from our stocked warehouse on orders placed before 3 PM CST.
