The Goodman 10123519 is a genuine OEM manual-reset high-limit switch built as an exact-fit replacement for the AMS951155DXA gas furnace and compatible Goodman/Amana models. This safety control monitors heat-exchanger temperature and shuts off the burners if the furnace overheats — protecting the unit and your home from a runaway high-heat condition. Because it is manual-reset, it must be pressed to restore operation after a trip, alerting you to investigate the underlying cause.

Specifications

Type: Manual reset high-limit / rollout safety switch
Function: Opens on overtemperature to shut off burners
Reset: Manual (press-to-reset button)
Fits: Goodman/Amana AMS951155DXA and compatible furnaces
OEM Part Number: 10123519

OEM vs. Generic

Limit switches are calibrated to a specific trip temperature. The OEM 10123519 is set to the exact cut-out point your furnace's certification requires, so it protects without nuisance tripping. Generic switches with a different temperature rating can either trip early (short-cycling) or too late (unsafe). For a safety control, OEM is strongly recommended.

Install Difficulty

Easy (2/5). About 15–20 minutes — cut power to the furnace, note and disconnect the two wire leads, unscrew the old switch from the burner or heat-exchanger panel, mount the new one, reconnect the leads, and restore power. A nut driver and basic care with wiring are all that's needed.
