The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-limit safety control engineered for the Goodman/Amana ACEC800603AXAB and compatible gas furnace platforms. This switch monitors heat-exchanger and plenum temperature and opens the gas/ignition circuit if the unit overheats — a critical safety device that prevents heat-exchanger damage and unsafe operation. Unlike auto-reset limits, the manual-reset design requires you to physically press the button to restore operation, ensuring a technician inspects the root cause before the furnace runs again.

OEM vs. Generic

This is the factory OEM part — exact trip temperature, mounting bracket, and terminal orientation match your original. Universal/generic limit switches often carry a different temperature rating or footprint, which can cause nuisance trips or unsafe high-limit response. For a safety control, OEM is strongly recommended.

Installation Difficulty: Easy

Two spade terminals and two mounting screws. Always disconnect power before servicing. Most DIYers complete this in under 15 minutes; if the switch is tripping repeatedly, have the heat exchanger and airflow inspected by a licensed technician.
