The Goodman 0130F00010S Flame Sensor is a genuine OEM rectification sensor built for the WFD18045S3AXCC gas furnace and compatible Goodman/Amana models. The flame sensor confirms to the control board that a flame is present after ignition; when it becomes coated with oxide or fails, the furnace lights briefly and then shuts down — the classic short-cycling / no-heat fault. Installing the correct OEM sensor restores reliable flame proving and steady heating.
This genuine OEM Goodman sensor uses the factory rod length, bracket angle, and terminal so it seats correctly in the burner assembly and reads a stable microamp signal. Universal flame sensors may sit at the wrong depth in the flame, causing weak or erratic rectification and repeat lockouts. OEM ensures the right signal the first time.
Easy (2/5). Roughly 15 minutes with a nut driver. Shut off power and gas, unclip the single spade connector, remove one screw, swap the sensor, and reconnect. A light polish habit on the new rod once a season keeps it reading clean.
