Mounted on the heat exchanger or blower deck, this automatic-reset limit switch continuously monitors supply-air temperature and de-energizes the gas valve if the furnace overheats — typically from restricted airflow, a dirty filter, or blower failure. It is one of the furnace's most important safety controls.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eAction: Normally closed, opens on temperature rise\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (closes when temperature drops)\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003ePrimary Fit: Goodman ACVM970803BNBA furnace\u003c\/li\u003e\n\u003cli\u003eFunction: Over-temperature shutdown of gas valve\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman OEM 20162904 is factory-set to your furnace's exact trip and reset temperatures and matches the original mounting footprint and insertion depth. Generic substitutes often differ in calibration or probe length, leading to short cycling on limit or, worse, a delayed safety response. OEM is strongly recommended for this critical control.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (2\/5)\u003c\/strong\u003e — Remove two mounting screws and transfer the wiring.
