This control continuously monitors heat-exchanger and plenum temperature and shuts off the burners if the furnace overheats — protecting against restricted airflow, a failed blower, or a cracked heat exchanger. It is one of the furnace's most important safety devices, and a failed limit will cause no-heat or repeated lockout conditions.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: 20162904\u003c\/li\u003e\n\u003cli\u003ePart type: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eFunction: Automatic overheat cutout, resets on cool-down\u003c\/li\u003e\n\u003cli\u003eMounting: Factory bracket to furnace vestibule\/plenum\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMH950904CXAG and compatible furnace models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe trip and reset temperatures are calibrated to this specific furnace platform.
