Mounted on the heat exchanger housing, this high-limit switch opens the circuit and shuts off the burners if the furnace overheats — protecting the heat exchanger and preventing unsafe operation. A failed limit switch is a common cause of short-cycling, no-heat calls, or a furnace that trips off on high temperature.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: 20162904\u003c\/li\u003e\n\u003cli\u003eFunction: Primary high-limit \/ temperature safety control\u003c\/li\u003e\n\u003cli\u003eType: Automatic-reset bimetal snap-disc limit\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WGFM28115V5CXAA and compatible gas furnaces\u003c\/li\u003e\n\u003cli\u003eMounting: Heat exchanger \/ vestibule panel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 20162904 is calibrated to Goodman's exact trip and reset temperatures for this furnace platform.
