Goodman 10123529 Manual Reset Rollout Limit Switch

The Goodman 10123529 is a genuine OEM manual reset limit (flame rollout) switch that protects your furnace from dangerous overheating and flame rollout conditions. It is a direct replacement for the Goodman and Amana AMS81205DXAB gas furnace. This normally-closed safety opens and cuts power to the gas valve if it senses excessive heat near the burner box, and stays open until it is manually reset — a deliberate design that forces a technician to diagnose the root cause before the furnace can fire again.

OEM Part Number: 10123529
Type: Manual reset rollout limit switch
Function: Normally closed, opens on overtemperature
Reset: Manual (push-button)

OEM vs. Generic

Safety switches must trip at a precise temperature. This OEM Goodman switch is calibrated to the factory trip point and mounts with the correct bracket and terminal spacing. Generic switches with the wrong set point can nuisance-trip or, worse, fail to trip. For a life-safety component, always use OEM.

Install Difficulty

Easy (2 of 5). About 15 minutes. Turn off gas and power first. Unplug the two spade terminals, remove the mounting screws, install the 10123529 in the same orientation, and reconnect. If this switch had tripped, find and correct the cause (blocked flue, cracked heat exchanger, or dirty burners) before returning the unit to service.
