The Goodman 0130F00010S Flame Sensor is a genuine OEM replacement for the WFD18090S4BXCB gas furnace. The flame sensor is a metal rectification rod that confirms a flame is present after ignition; if it doesn't detect flame, the control board closes the gas valve for safety. A dirty, corroded, or failing flame sensor is the single most common cause of a furnace that lights briefly then shuts off (short-cycling) or locks out on repeated ignition attempts.
The OEM 0130F00010S delivers the exact rod length, bend, and mounting bracket for correct positioning in the flame — critical for a strong microamp signal. Generic sensors often need trimming or bending and may sit in the wrong part of the flame, producing intermittent faults. For reliable flame proving, the genuine OEM part is worth the small premium.
Easy (1 of 5). Shut off power, remove one screw, unplug the wire, and swap the sensor. Many technicians clean the old rod with fine emery cloth first; if the fault returns, replace with this OEM sensor. A quick 10-minute repair.
