The Goodman 0130F00010S Flame Sensor is a genuine OEM flame-rectification rod built for the Goodman WFM18070S3AXCC furnace and compatible models. The sensor confirms flame presence after ignition; when it degrades or carbons over, the control board shuts off the gas valve, causing short-cycling, intermittent no-heat, or lockouts.
Replacing a worn flame sensor is one of the most common furnace repairs and restores reliable, safe burner operation.
OEM Goodman sensors use the correct rod length, alloy, and bracket geometry for a reliable microamp signal and a bolt-in fit. Generic sensors may have mismatched rod positioning or weaker signal output, leading to nuisance lockouts. OEM ensures consistent flame sensing.
Easy — typically one screw and a single spade connector. Shut off power and gas, remove the old sensor, install the new one, and reconnect. Most DIYers complete this in under 15 minutes.
