Mounted on the heat exchanger or blower deck, this safety device continuously monitors supply-air temperature and cuts power to the gas valve if the furnace overheats — typically from restricted airflow, a dirty filter, or a failed blower. When the temperature returns to a safe range, the control automatically resets and allows the furnace to fire again. A furnace that short-cycles, trips on limit, or fails to heat often needs this control replaced.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Automatic-reset primary limit \/ high-temperature safety control\u003c\/li\u003e\n\u003cli\u003eFunction: Interrupts burner operation on over-temperature\u003c\/li\u003e\n\u003cli\u003eFit: Goodman WFD195045S3BAB and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eMount: Heat exchanger \/ blower compartment (bracket mount)\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 20162904 is calibrated to the exact trip and reset temperatures Goodman specifies for this furnace's heat exchanger. Generic universal limits may open at the wrong setpoint — nuisance-tripping during normal operation or, worse, failing to protect against a genuine overheat. Because this is a life-safety component, the genuine OEM control is the recommended choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy to moderate — DIY-capable with basic tools.\u003c\/strong\u003e Cut power at the disconnect, remove two mounting screws, unplug the wire leads, and swap in the new control.
