The Goodman/Amana 10123529 Manual Reset Limit Switch is a genuine OEM high-limit safety control engineered for the AMEC801005CNAA gas furnace and compatible Goodman and Amana models. This switch monitors heat-exchanger temperature and opens the burner circuit if the furnace overheats, protecting the equipment and your home from unsafe operating conditions. Because it is a manual reset device, it must be pressed back in by hand after a trip — a deliberate safety design that flags a persistent airflow or overheating problem before the furnace is allowed to run again.

  • Type: Manual reset high-limit safety switch
  • Function: Opens burner/gas circuit on overheat
  • Fits: AMEC801005CNAA and compatible Goodman/Amana furnaces
  • Reset: Manual (push-button)
  • Brand: Genuine Goodman/Amana OEM

OEM vs. Generic: The genuine OEM 10123529 is calibrated to the exact trip temperature specified for your furnace, guaranteeing correct safety response and a precise fit in the factory mounting location. Generic equivalents may carry a different trip point or mounting footprint, which can cause nuisance trips or improper protection. For a critical safety control, we recommend the OEM part.

Install difficulty: Easy (2/5). Disconnect furnace power, remove the two mounting screws, transfer the wire leads to the new switch, and remount. A repair typically completed in 15–20 minutes. Always cut power at the breaker before servicing and, if you are unsure why the switch tripped, have a licensed HVAC technician diagnose the underlying cause.
