The Goodman 10123529 is a genuine OEM manual reset limit switch for the AMES921205DNAA gas furnace. This safety control opens the low-voltage circuit and shuts down the burners if it senses an overheat or flame-rollout condition, protecting the heat exchanger and household. Because it is a manual reset device, it must be reset by hand once the fault is cleared — a deliberate design that flags recurring problems.

Specifications

Part number: 10123529
Type: Manual reset high-limit / rollout safety switch
Function: Opens on overheat / flame rollout to shut off ignition
Reset: Manual push-button
Fits: Amana/Goodman AMES921205DNAA and compatible furnace platforms

OEM vs. Generic

The OEM 10123529 is calibrated to the exact trip temperature Goodman specifies for this furnace. Generic switches with different trip points can nuisance-trip or, worse, fail to protect the unit. For a safety-critical control like this, we strongly recommend the OEM part.

Installation Difficulty

Moderate (3/5). Shut off power and gas, remove the two mounting screws, transfer the wire terminals, and reinstall. Basic hand tools required. If the switch trips repeatedly after replacement, have a technician diagnose the underlying overheat cause.
