The Goodman 10123517 Manual Reset Limit Switch is a genuine OEM safety control for the WGFD293090V5DAA gas furnace and compatible Goodman/Amana models. This high-limit switch monitors heat-exchanger and plenum temperatures and cuts power to the gas valve if the furnace overheats — protecting the heat exchanger from cracking due to restricted airflow or blower failure. Its manual-reset design requires a deliberate button press to restore operation, alerting the homeowner that an overheat event occurred.
Limit switches must open at a precise trip temperature. Generic switches with the wrong set point either nuisance-trip or fail to protect the heat exchanger. This OEM 10123517 is calibrated to Goodman's exact specification for correct, safe cutoff every time.
Easy (1/5) — Cut power, remove the two mounting screws, transfer the wire leads, and mount the replacement. About 10 minutes. If the switch keeps tripping after replacement, investigate airflow (dirty filter, failing blower). Verify model fit before ordering.
