The Goodman 10123529 is a genuine OEM manual reset rollout limit switch for the AMS80403AXAB 80,000 BTU, 80% AFUE gas furnace and compatible AMS80 series models. This safety control monitors for flame rollout — a dangerous condition where flames escape the heat exchanger — and shuts the furnace down if excessive heat is detected at the burner box. Because it is manual-reset, it will not automatically restart, forcing a technician to inspect the cause before the furnace can run again.

Specifications

Part type: Manual reset flame-rollout limit switch
Part number: 10123529
Fits model: AMS80403AXAB and related AMS80 series furnaces
Function: Opens on rise; manual reset button restores circuit
Type: Normally-closed thermal safety switch

OEM vs. Generic

This OEM switch is calibrated to Goodman's exact trip temperature and terminal orientation. Generic switches with different trip points can nuisance-trip or, worse, fail to protect against rollout. For a life-safety component, always use the OEM-specified part.

Installation Difficulty

Easy (1/5). Two-wire replacement secured by screws. Disconnect power first. However, a tripped rollout switch signals an underlying problem (blocked heat exchanger, poor venting) — have a licensed HVAC technician diagnose the root cause before returning the furnace to service.
