Goodman 10123539 Manual Reset Limit Switch

The Goodman 10123539 is a genuine OEM manual reset limit switch that serves as a direct-fit safety control for the GMPE075-3 gas furnace and other compatible Goodman/Amana models. This normally-closed thermal switch trips open when it detects excessive heat or flame rollout — typically caused by a cracked or blocked heat exchanger, plugged flue, or failed inducer — cutting power to the gas valve to prevent a hazardous condition. Its manual reset button ensures the furnace stays locked out until a technician investigates the cause.

OEM vs. Generic

As a combustion safety device, the trip temperature must precisely match Goodman's specification. The genuine OEM 10123539 delivers the correct calibrated set point and dependable manual-reset action, while generic alternatives risk incorrect trip points. For any furnace safety switch, OEM is the right choice.

Installation Difficulty

Easy to Moderate — power off, remove the spade connectors, unscrew and replace the switch, then press reset. Never bypass this switch; repeated trips indicate a serious fault that must be corrected by a licensed HVAC professional.
