It monitors heat-exchanger temperature and opens the circuit to shut 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 or a furnace that fires briefly then shuts down.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003cli\u003ePart Type: Primary Limit Switch\u003c\/li\u003e\n\u003cli\u003eTemperature Rating: 150°F trip point\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas Furnace\u003c\/li\u003e\n\u003cli\u003eDirect-fit for model AKSS920704CXAA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOEM limit switches are calibrated to the exact trip temperature your furnace's control logic expects.
