OEM Carrier Flame Sensor for PY3PPA048115NB HVAC Package Unit

The flame sensor tells your PY3PPA048115NB's control board whether a flame is truly present once the gas valve opens. It is a single rod that sits in the burner flame and operates by flame rectification — the burning flame passes a small microamp current to the board, and that current is the only signal the board trusts to keep gas flowing safely. Over time the rod builds up carbon and oxide or the metal fatigues, and the signal falls below the board's threshold. The result is the most common no-heat complaint there is: the burners light, run for roughly 3 to 7 seconds, then shut off and try again, and after several failed cycles the furnace locks out cold — typically on the harshest winter mornings. This OEM flame sensor uses the correct high-temperature stainless/Kanthal rod and porcelain insulator, set at the exact depth and angle the burner assembly was designed around. A healthy sensor produces about 1–6 microamps of rectified flame current, and genuine-part tolerances keep that signal strong and consistent. Why OEM matters here: aftermarket sensors commonly use a thinner rod or altered mounting geometry, so the tip sits too shallow in the flame and yields a marginal microamp reading that slips into nuisance lockouts within a single season. The genuine part holds both its signal strength and its position. Install difficulty: 1/5. Tools: a 1/4" nut driver for the single mounting screw, plus a multimeter (microamp setting) and fine emery cloth if you want to test or clean the rod. #1 safety warning: shut off the gas supply and cut power to the unit before reaching into the burner compartment.
