The Goodman 10123529 is a genuine OEM manual-reset high-limit / rollout safety switch for the AMES800603BNAA gas furnace. This safety control senses excessive temperature — from a blocked flue, failed blower, dirty filter, or flame roll-out — and opens the circuit to shut off the burners, protecting the heat exchanger and preventing unsafe operation.

Because it is a manual-reset device, it must be pressed to reset after a trip and will not automatically re-close. A switch that has failed open, become weak, or trips repeatedly should be replaced with the exact OEM part to keep the furnace's built-in safety chain intact.

Part number: 10123529
Type: Manual-reset high-limit / rollout safety switch
Action: Opens on overtemperature; requires manual reset
Function: Shuts off burners to prevent overheating
Fits: Goodman / Amana AMES800603BNAA and compatible furnaces
Finish: OEM direct replacement

OEM vs. Generic: The 10123529 is calibrated to the precise trip temperature and reset behavior Goodman specifies for this furnace, and its terminal and bracket match the factory location. Substituting an incorrect temperature rating defeats the safety design. For any safety switch, OEM is the recommended choice.

Installation difficulty: Easy (2/5). Cut power, disconnect the two spade terminals, remove the mounting screws, and install the new switch in the same orientation. About 15 minutes with basic tools. If the switch keeps tripping, diagnose the underlying overheat cause before returning the furnace to service.
