The Goodman 10123529 is a genuine OEM manual reset high-limit switch built for GDH80403AXAA and compatible Goodman/Amana gas furnaces. This safety-critical component opens the control circuit and shuts off the burners if furnace temperatures exceed the factory-set threshold, protecting the heat exchanger and cabinet from overheating.

A manual reset design requires an operator to press the button to restore heating after a trip — a deliberate safeguard that flags underlying issues such as a dirty filter, blocked flue, or failing blower. If your furnace repeatedly locks out on high limit, replacing a worn or drifted switch restores accurate, dependable protection.

  • Part Number: 10123529
  • Type: Manual reset high-limit switch
  • Function: Over-temperature safety cutout
  • Fits: GDH80403AXAA and compatible Goodman/Amana furnaces
  • Reset: Manual push-button

OEM vs. Generic: The OEM switch is calibrated to the exact trip and reset temperatures Goodman engineered for this furnace. Generic switches with mismatched set points can trip early (no heat) or too late (safety risk). For safety devices, OEM is the responsible choice.

Install Difficulty: Easy. Two mounting screws and two spade terminals. Roughly 15 minutes with a nut driver. Shut off gas and 120V power before servicing.
