Mounted on the heat-exchanger bulkhead, this primary limit monitors supply-plenum temperature and shuts off the burners if airflow is lost or temperature climbs too high, protecting the heat exchanger from cracking. It typically auto-resets once temperature returns to normal, restoring heat after a nuisance condition clears.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eFunction: Opens gas circuit on over-temperature\u003c\/li\u003e\n\u003cli\u003eOEM part number: 20162904\u003c\/li\u003e\n\u003cli\u003eCompatible model: AMEC800804CXAA\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (temperature-sensing)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman 20162904\u003c\/strong\u003e uses the factory-specified trip and reset temperatures and the correct sensing-element length for proper placement in the airstream.
