The Goodman 10123529 is a genuine OEM manual-reset limit switch for the AMEC800403ANAB gas furnace and compatible Goodman/Amana models. This is a safety cutout: it opens the ignition circuit and shuts the furnace down if it senses an over-temperature or flame-rollout condition, then stays open until you press the reset button. A tripped or failed switch is a frequent cause of a furnace that won't light or locks out on safety. If yours has failed, replace it — never bypass a safety limit.

Part number: 10123529
Type: Manual reset limit / rollout switch
Reset: Manual (push-button)
Fits: AMEC800403ANAB and related Goodman/Amana furnaces
Function: Over-temperature / flame-rollout safety cutout
Connection: Spade terminals, OEM-matched trip temperature

OEM vs. Generic: The OEM 10123529 is calibrated to the exact trip temperature Goodman specified for this furnace. A generic switch with the wrong rating either nuisance-trips or, worse, fails to trip when it should — defeating the safety. On a life-safety component, always use the genuine OEM part.

Install difficulty: Easy (2/5). Cut power to the furnace, note or photograph the wiring, remove the two mounting screws, transfer the spade connectors to the new switch, and remount. About 15–20 minutes. After repair, find and correct the root cause (blocked flue, dirty burners, weak inducer) so the limit doesn't trip again.
