The Goodman 10123529 Manual Reset Limit Switch is the genuine OEM overheat safety control for AMEC800804CXAA and related Amana/Goodman gas furnaces. This normally-closed thermal switch opens and cuts power to the gas valve if the furnace exceeds a safe temperature, then requires a manual reset — a deliberate design that forces a technician to inspect the root cause (blocked airflow, failed blower, or flame rollout) before the furnace can restart.

Specifications

Part type: Manual reset high-limit / rollout switch
Contacts: Normally closed, opens on temperature rise
OEM part number: 10123529
Compatible model: AMEC800804CXAA
Brand: Goodman / Amana
Reset: Manual (push-button)

OEM vs. Generic

The OEM Goodman 10123529 is calibrated to the exact trip temperature specified for this furnace, so it protects the heat exchanger without nuisance trips. Generic switches with the wrong setpoint either trip early or fail to protect against genuine overheating — a safety risk. For any furnace safety control, OEM is the right choice.

Install Difficulty

Moderate (2/5). Power off the furnace, disconnect the two spade terminals, remove the mounting screws, install the new switch in the same orientation, and reconnect. Always diagnose and clear the overheat cause before resetting.

Gas furnace safety controls should be serviced by a qualified HVAC technician.
