OEM Goodman 10123529 Manual Reset Limit Switch

The genuine Goodman 10123529 is a manual-reset high-limit/rollout safety switch built for the AMH80403ANBB gas furnace. It opens the control circuit if it senses excessive temperature — protecting the heat exchanger and cabinet from overheating or flame rollout. Because it is a manual-reset device, a tripped switch signals an underlying problem (restricted airflow, blocked flue, or overfiring) and must be physically reset after the fault is corrected.

Specifications

Part number: 10123529
Type: manual reset high-limit / rollout safety switch
Function: opens on overtemperature to shut down the burner circuit
Fits: Goodman/Amana AMH80403ANBB furnaces
Includes reset button for post-fault restart

OEM vs. Generic

This is a safety-critical control, so the OEM trip and reset temperatures matter. The genuine 10123529 is calibrated to the exact set point Goodman specified for this furnace. Generic "universal" limits may trip early (nuisance shutdowns) or late (dangerous overtemperature), and can void heat-exchanger warranty coverage. Always match OEM for safety switches.

Installation Difficulty

Easy — 15–20 minutes. Cut power, disconnect the two spade terminals, remove the mounting screws, install the new switch, and reconnect. Never bypass a limit switch. If it keeps tripping, diagnose the airflow or venting cause.

Confirm your furnace is the AMH80403ANBB before ordering; several Goodman limit switches look similar but carry different set points.
