Goodman 10123529 Manual Reset Limit Switch

The Goodman 10123529 is a genuine OEM manual reset limit switch engineered as a direct-fit safety control for the AMH81205DXAA gas furnace and other compatible Goodman and Amana furnace models. This switch protects your heat exchanger and blower compartment by opening the control circuit when it detects an over-temperature or flame rollout condition, shutting the burners down before damage or a safety hazard can occur. Because it is a manual reset design, it stays open after a fault until the button is physically pressed — giving you a clear signal that the unit tripped for a reason worth investigating.

Specifications

  • Type: Manual reset limit / rollout safety switch
  • Fit: OEM direct replacement for Goodman AMH81205DXAA furnace
  • Function: Opens control circuit on over-temperature condition
  • Reset: Manual push-button
  • Brand: Genuine Goodman / Amana OEM

OEM vs. Generic

Our OEM Goodman 10123529 delivers factory-calibrated trip temperatures and exact terminal geometry, so it drops in without wiring modifications and preserves your furnace's original safety certification. Generic universal switches may trip at slightly different temperatures and can require adapter brackets or spliced leads — acceptable in a pinch, but the genuine part is the reliable long-term choice for a safety-critical component.

Installation Difficulty

Easy (1 of 3). Most homeowners with basic tools can swap this switch in 15–20 minutes: cut power, disconnect the two spade terminals, remove the mounting screws, and install the replacement. If the switch has tripped repeatedly, have a qualified HVAC technician diagnose the underlying cause (airflow restriction or overfiring) before returning the unit to service.
