The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM safety control engineered as a direct-fit replacement for the AMEC800805CNAA gas furnace and other compatible Goodman and Amana models. This high-limit switch monitors heat exchanger and blower-compartment temperature, tripping to interrupt the gas valve if the furnace overheats. Because it is a manual reset design, it will not self-restore after a fault, prompting the homeowner or technician to inspect the underlying cause (blocked filter, failed blower, or restricted ductwork) before the furnace can restart.

Type: Manual reset high-limit / rollout safety switch
Function: Opens gas circuit on over-temperature
Reset: Manual push-button
Mounting: Direct OEM bracket fit
Equipment: Goodman & Amana gas furnaces

OEM vs. Generic: The genuine OEM 10123529 is calibrated to the exact factory trip temperature and terminal orientation specified for your furnace, ensuring correct safety-circuit operation and preserving warranty compliance. Generic universal limit switches may trip at incorrect temperatures or require terminal adapters, risking nuisance lockouts or unsafe operation. For a safety-critical control we strongly recommend the OEM part.

Installation difficulty: Moderate. A competent DIYer can complete the swap in 15–25 minutes with a nut driver and needle-nose pliers, but the furnace must be powered down at the disconnect first. If you are unsure why the switch tripped, have a licensed HVAC technician diagnose the fault before replacing.
