The Goodman 10123529 Manual Reset Rollout Limit Switch is a genuine OEM flame-rollout safety control engineered for the AMH80403ANBC gas furnace and compatible Goodman/Amana 80% AFUE models. This normally-closed thermal switch mounts on the burner assembly and instantly interrupts the gas valve and ignition circuit if flames roll out of the burner box — a critical protection against heat exchanger cracks, blocked venting, or restricted combustion airflow.

Because it is a manual reset device, the switch will not silently self-restore after a fault. The homeowner or technician must press the reset button, prompting an inspection of the underlying cause before the furnace fires again.

Specifications

Function: Opens on high temperature to shut off gas/ignition
Reset: Manual push-button
Fits: Goodman/Amana AMH80403ANBC and related 80% furnaces
OEM Part #: 10123529

OEM vs. Generic

The genuine OEM 10123529 is calibrated to the exact trip temperature specified by Goodman engineering, ensuring proper safety response and factory warranty compliance. Generic aftermarket switches may use approximate trip points and looser tolerances, which can cause nuisance trips or delayed shutoff on a safety-critical circuit. For a component that protects against combustion hazards, OEM is strongly recommended.

Installation Difficulty

Easy (2/5) — Two-wire spade connection and a simple bracket mount. Always shut off gas and power at the furnace disconnect before servicing. If the switch has tripped, diagnose venting, airflow, and heat exchanger integrity before resetting.
