Mounted on the heat-exchanger\/plenum, this primary limit continuously monitors supply-air temperature and opens the gas-valve circuit if the furnace overheats — most often from restricted airflow, a failed blower, or a dirty filter. It is the main over-temperature safeguard protecting the heat exchanger and preventing hazardous operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit temperature control (auto-reset)\u003c\/li\u003e\n\u003cli\u003eFunction: Opens gas circuit on plenum over-temperature\u003c\/li\u003e\n\u003cli\u003eMount: Furnace-specific bracket \/ setpoint\u003c\/li\u003e\n\u003cli\u003eFit: Direct OEM replacement for Goodman GCH950703BXAC\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (genuine OEM)\u003c\/li\u003e\n\u003cli\u003ePart number: 20162904\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine 20162904 is calibrated to Goodman's exact trip and reset temperatures for this furnace and uses the correct insertion depth and bracket.
