This normally-closed thermal switch monitors plenum temperature and cuts power to the burners if the furnace overheats — protecting the heat exchanger and preventing unsafe operation. A tripped or failed limit switch is a common cause of short-cycling and no-heat calls.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit \/ auto-reset thermal switch\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 150°F\u003c\/li\u003e\n\u003cli\u003eContact Configuration: Normally closed (opens on rise)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GKS90703BXAF and compatible GKS90 furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine OEM 20162903 is calibrated to the exact 150°F trip point and mounting footprint specified for your furnace.
