Mounted on the heat exchanger or blower deck, this auto-reset switch monitors supply-air temperature and opens the circuit if the furnace overheats — typically due to restricted airflow from a dirty filter, closed vents, or a failing blower. When temperatures return to normal, the switch automatically resets, protecting the heat exchanger from thermal damage.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit switch (auto reset)\u003c\/li\u003e\n\u003cli\u003eTrip point: 150°F (opens on temperature rise)\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat \/ airflow-loss safety shutoff\u003c\/li\u003e\n\u003cli\u003eFit: Goodman GKS90704CXAD and compatible Goodman \u0026amp; Amana 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 \u003cstrong\u003egenuine Goodman OEM limit switch\u003c\/strong\u003e is factory-set to the exact 150°F trip point specified for your furnace. Generic replacements with different set points can nuisance-trip during normal operation or, worse, fail to trip when the unit truly overheats. Because this is a primary safety device, we strongly recommend the OEM part with the correct rating.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2\/5).\u003c\/strong\u003e Disconnect power, note the two wire connections, remove the mounting screws, and install the new switch in the same orientation.
