The Goodman 10123529 is a genuine OEM manual reset limit switch used on the Amana/Goodman AMH80805CXBD 80% AFUE gas furnace. This normally-closed safety switch trips on excessive temperature — typically from flame rollout or a blocked heat exchanger — and stays open until it is manually reset with the push button, forcing a technician to inspect the cause before the furnace can fire again.

Specifications

OEM Part Number: 10123529
Type: Manual reset high-limit / rollout safety switch
Contacts: Normally closed, manual push-button reset
Function: Trips on overheat / flame rollout and locks out until reset
Fits: Amana / Goodman AMH80805CXBD furnace

OEM vs. Generic

Because this is a lockout safety device, the exact trip temperature and reset behavior matter. The OEM switch carries Goodman's specified set point and terminal layout, so it protects the furnace precisely as designed. Generic substitutes with different set points can either nuisance-trip or fail to protect against a genuine rollout condition. OEM is strongly recommended here.

Installation

Difficulty: Easy (2/5). De-energize the furnace, remove the two mounting screws, transfer the leads to the matching terminals on the new switch, and remount. A 10-15 minute job. Important: a tripped manual reset switch signals an underlying problem — inspect the heat exchanger, venting, and burners before returning the furnace to service.
