The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM safety control for the AMEC800805DXAA gas furnace and compatible Goodman/Amana models. This normally-closed high-limit switch opens the control circuit if the heat exchanger or burner box overheats, shutting down the furnace to prevent damage. Being a manual reset type, it must be physically reset by pressing its button after a trip — a deliberate safety feature that flags a persistent problem such as a blocked flue or failed blower.

OEM part number: 10123529

OEM vs. Generic

OEM limit switches are calibrated to Goodman's exact trip temperature and terminal spacing. Because this is a life-safety device, we strongly recommend the genuine OEM part — a generic switch with the wrong trip point can nuisance-trip or, worse, fail to protect the furnace.

Installation Difficulty

Easy (2/5). Power off the furnace, unplug the two wire leads, remove the mounting screws, and install the new switch. 10-15 minutes with a nut driver. Always diagnose the root cause of any overheat before replacing.
