OEM Carrier Furnace Flame Sensor Replacement for PY1PNA036080ACBA

The flame sensor is a thin metal rod that sits in the burner flame and proves to the control board that a flame is actually present after the gas valve opens. When it gets coated with oxide or carbon, it can no longer pass the tiny microamp signal the board needs, so the board shuts the gas off as a safety measure. The classic symptom is a furnace that lights for a few seconds and then shuts down, cycling on and off repeatedly (short-cycling) and never reaching temperature, leaving the home with little or no heat. This OEM flame sensor uses the correct rod length, bend, ceramic insulator, and terminal connection for this furnace. Maintaining the factory flame-rod geometry and gap keeps the rod seated in the strongest part of the flame, so it reads a healthy flame-rectification current (typically 1–6 microamps) and avoids nuisance lockouts. OEM matters because flame sensing depends on consistent, clean rectification. Generic sensors with the wrong rod length or alloy sit in a weaker part of the flame or develop a poor contact, producing a marginal signal the board reads as no flame. That triggers repeated lockouts and excess gas-valve cycling. An OEM rod and insulator hold their position and signal reliably over thousands of heating cycles. Install difficulty: 1/5. Tools needed: a 1/4" nut driver and fine steel wool or emery cloth (replacement, not just cleaning, is the lasting fix). #1 safety warning: turn off the gas supply and the furnace power switch before removing the sensor from the burner assembly.
