The Goodman 10123529 is a genuine OEM manual reset limit switch for the AMH80453AXCB gas furnace and related Amana and Goodman models. This safety control opens the ignition circuit if it senses an over-temperature or flame-rollout condition, shutting the furnace down to protect the heat exchanger and cabinet. Because it is a manual-reset device, it stays open until a technician presses the reset button, ensuring the underlying fault gets investigated.

A limit switch that has failed open, will not reset, or nuisance-trips leaves the furnace locked out with no heat. Replacing it with the correct OEM switch restores reliable over-temperature protection.

OEM vs. Generic

OEM limit switches are calibrated to this furnace's exact trip temperature and mounting footprint. A generic switch with the wrong set point can trip early (nuisance no-heat) or, worse, fail to trip when it should — defeating a critical safety. For a life-safety control, always use the genuine OEM part.

Installation

Difficulty: Easy (1–2/5). Cut power at the disconnect, note the wire terminals, remove the two mounting screws, transfer the leads to the new switch, and remount. About 15–20 minutes. If the old switch was tripping, diagnose the root cause (blocked flue, weak inducer, dirty burners) before returning the furnace to service, and press the reset once installed.

Genuine OEM replacement part. Safety-control work should be done by a qualified technician. Verify model and serial before ordering.
