The Goodman 0130F00010S Flame Sensor is the OEM flame-rectification rod for the GSMS100-4 gas furnace. It confirms the burner has lit and tells the control board to keep the gas valve open. When the sensor's tip oxidizes or the rod cracks, the furnace ignites and then shuts down within seconds — the classic short-cycle and flame-loss lockout. A fresh sensor is the fastest, lowest-cost cure for these faults.
The OEM 0130F00010S uses the exact rod length and mounting bracket for the GSMS100-4 burner assembly, ensuring the tip sits in the correct part of the flame. Our generic flame sensor rod delivers the same rectification performance at a lower price, though bracket alignment should be checked on install. Choose OEM for a guaranteed drop-in fit.
Easy (1/5). Cut power, remove the single mounting screw, unplug the spade connector, and reverse to install. Wipe the flame path clean and avoid touching the new rod with bare fingers. Replacement takes about 10 minutes.
Compatible with Goodman GSMS100-4 furnaces. Verify your existing part number before ordering.
