Mounted on the heat-exchanger bulkhead, it continuously monitors supply-plenum temperature and de-energizes the gas valve if the furnace overheats — typically from restricted airflow, a dirty filter, or a failed blower. It auto-resets once temperature returns to a safe range, protecting the heat exchanger from cracking.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Primary (auto-reset) high-limit control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Action:\u003c\/strong\u003e Normally closed, opens on high temperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Heat-exchanger \/ plenum bracket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 20162904\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (fits Amana AMH-series)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e AMH80803BXBA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 20162904\u003c\/strong\u003e ships with the correct trip temperature and probe length for the AMH cabinet.
