Goodman 10123529 Manual Reset Limit Switch

The 10123529 is a genuine OEM Goodman/Amana manual reset high-limit switch for the AMH81005CXAA gas furnace. This safety control opens the ignition/gas circuit if it senses excessive temperature — typically from a blocked flue, failed blower, dirty filter, or flame rollout — and stays open until manually reset, preventing the furnace from re-firing into an unsafe condition. A tripped or failed limit switch is a common cause of no-heat calls, so an exact-fit OEM replacement is essential to restore safe operation.

Part Number: 10123529
Type: Manual reset high-limit / rollout switch
Fits: Goodman/Amana AMH81005CXAA and compatible models
Function: Opens gas/ignition circuit on overtemperature; requires manual reset
Mounting: Factory bracket/terminal match

OEM vs. Generic

The OEM 10123529 is calibrated to the exact trip temperature Goodman specifies for this furnace. Generic limits with the wrong setpoint can either nuisance-trip (repeated no-heat) or fail to protect against a genuine overheat — a serious safety risk. For a life-safety control, always use the genuine part.

Installation Difficulty

Easy (2/5). Disconnect power and gas, unplug the two spade terminals, remove the mounting screws, and install the replacement in the same orientation. Diagnose the root cause of any trip before returning the furnace to service. Typically 15–20 minutes.

Fitment guaranteed. Questions? Contact info@nationalhvacparts.com.
