Goodman 10123529 Manual Reset Limit Switch

The Goodman 10123529 is a genuine OEM manual reset limit (rollout) switch for the AMS80805CXAD 80% AFUE gas furnace and compatible Goodman/Amana models. This safety control opens the ignition circuit if it senses abnormal heat or flame rollout, protecting the heat exchanger and cabinet. Because it is a manual reset device, it requires a physical button press to restore operation after a trip — a deliberate design that flags a condition needing inspection.

Function: Opens on over-temp / flame rollout
Reset: Manual push-button
Fits: AMS80805CXAD and related 80% Goodman/Amana furnaces

OEM vs. Generic

Safety switches are calibrated to a specific trip temperature. The OEM Goodman 10123529 matches the factory trip point exactly. Generic substitutes may trip early (nuisance shutdowns) or late (reduced protection). For a safety-critical control, OEM is strongly recommended.

Installation Difficulty

Easy (2/5). Cut power, unplug the two wire leads, remove the mounting screws, and install the replacement in the same orientation. About 10–15 minutes. If the switch tripped, have a technician diagnose the root cause first.
