The Goodman 10123519 Manual Reset Limit Switch is a genuine OEM high-limit safety control engineered for the WGFM195115S5DAD gas furnace and compatible Goodman/Amana models. This switch continuously monitors heat-exchanger and plenum temperatures and trips to interrupt burner operation whenever the furnace overheats — a critical line of defense against cracked heat exchangers and fire hazards. Because it is a manual reset device, it stays open after a fault until an operator presses the button, prompting a proper diagnosis rather than silent short-cycling.

OEM vs. Generic

This is a factory OEM component built to Goodman's exact trip-temperature and mounting spec, guaranteeing correct calibration and bracket fit. Generic aftermarket switches are lower cost but may vary in trip point and lead length, risking nuisance trips or delayed shutdowns. For a safety control, we recommend the OEM part.

Installation Difficulty

Easy (2/5). A basic swap for anyone comfortable removing the furnace access panel: shut off power and gas, unplug the two spade terminals, unscrew the switch, and reinstall the replacement in the same orientation. Typical job time is 15–20 minutes. If your limit keeps tripping after replacement, have a technician inspect airflow and the heat exchanger.

Restore safe, reliable heating with genuine Goodman parts.
