OEM Carrier Gas Furnace Flame Sensor Rod for PG92SBS48100CBAA

The flame sensor is a single metal rod that sits in the burner flame and confirms to the control board that the gas actually ignited. It works by flame rectification — the lit flame conducts a tiny DC current (microamps) from the rod to ground, telling the board it is safe to keep the gas valve open. When the sensor is dirty, cracked, or worn, the furnace will light normally and then shut the gas off within a few seconds because the board no longer 'sees' a flame. The classic symptom is short-cycling: the burners ignite, run briefly, drop out, retry several times, and finally lock out into a no-heat fault. This is one of the most common service issues on the Carrier PG92 series and is frequently misdiagnosed as an igniter or board failure. This genuine OEM flame sensor uses a high-temperature rod sized and positioned for the PG92SBS48100CBAA burner assembly. A healthy flame signal typically reads in the 1–6 microamp DC range; a reading that drifts below roughly 1 µA indicates a fouled or failing rod. Generic sensors often use the wrong rod length, diameter, or mounting angle, which places the tip incorrectly in the flame and produces a weak, unstable signal — leading right back to the short-cycling you're trying to fix. The OEM rod restores the correct flame-current reading the first time. Install difficulty: 1 of 5. Tools needed: 1/4" nut driver and fine emery cloth or steel wool to clean the new rod's mounting surface. #1 safety warning: shut off the gas supply and kill power at the breaker before removing the sensor, and never sand the rod with abrasive grit that leaves residue.
