Mounted on the heat exchanger bulkhead, it monitors supply-plenum temperature and shuts off the burners if the furnace overheats — typically caused by a dirty filter, weak blower, or closed registers. It is an automatic-reset control that closes again once temperature returns to a safe range.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit temperature control (automatic reset)\u003c\/li\u003e\n\u003cli\u003eFunction: Opens gas\/ignition circuit on plenum overheat\u003c\/li\u003e\n\u003cli\u003eMount: Bracket-mounted disc\/bimetal sensor\u003c\/li\u003e\n\u003cli\u003eTerminals: 1\/4\" quick-connect spade\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana furnaces (AMH80804BXBA and related)\u003c\/li\u003e\n\u003cli\u003eOEM part number: 20162904\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003ePrimary limits are matched to a specific trip temperature and probe length for each furnace model.
