The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-limit safety control engineered for Amana/Goodman AMH80903BXCB gas furnaces and compatible 80% AFUE models. This manual-reset limit protects your furnace by cutting power to the gas valve if the heat exchanger or plenum exceeds a safe temperature, guarding against overheating, restricted airflow, and heat-exchanger damage. When it trips, the switch must be manually reset — a deliberate safety feature that prompts a service check before the furnace can fire again.

OEM vs. Generic

This is a genuine OEM Goodman/Amana component built to the exact trip temperature and mounting footprint your furnace was designed around. Generic aftermarket limits may trip at incorrect temperatures or fit loosely, causing nuisance shutdowns or bypassing critical protection. For a safety-rated part, OEM is strongly recommended.

Installation Difficulty

Easy (1 of 5). Two mounting screws and two spade terminals. Always shut off gas and electrical power before servicing. If the switch has tripped repeatedly, have a qualified HVAC technician diagnose the root cause (airflow, dirty filter, or failing blower) before replacing.
