The Goodman 10123534 Manual Reset Limit Switch is a genuine OEM high-limit safety control for the AMSS920804CNAA gas furnace and compatible Goodman/Amana models. This normally-closed thermal switch opens the control circuit if it senses excessive temperature — typically from a blocked flue, dirty filter, or failed blower — and requires a manual reset button press to restore operation. It is a critical safety component that prevents overheating and potential heat-exchanger damage.

Specifications

Type: Manual reset high-limit / rollout safety switch

OEM vs. Generic

Because this is a safety-rated limit control, the OEM 10123534 is calibrated to the exact trip temperature your furnace was engineered for. Generic switches with mismatched set points can trip too early (nuisance lockouts) or too late (unsafe). For any safety device, always choose the genuine OEM part.

Installation Difficulty

Moderate. Requires disconnecting two spade wire terminals and removing one or two mounting screws. Basic DIY-friendly for those comfortable working around gas furnace wiring. Shut off gas and power before servicing, and never bypass a tripped limit switch — diagnose the root cause first.
