Mounted on the heat exchanger or blower deck, this auto-reset switch monitors supply-air temperature and cuts the gas valve if the furnace overheats — typically from restricted airflow, a dirty filter, or a failed blower. It closes again once temperatures return to normal, restoring the heat cycle automatically.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit switch\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 150°F\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (self-resetting)\u003c\/li\u003e\n\u003cli\u003eContacts: Normally closed\u003c\/li\u003e\n\u003cli\u003eCompatibility: AMES960403ANAA Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch is calibrated to the precise 150°F set point and probe\/disc length your furnace requires. Generic snap-disc limits with the wrong temperature rating or insertion depth can cause short-cycling or fail to protect the heat exchanger. On a safety limit, matching the factory spec exactly matters.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate.\u003c\/strong\u003e Turn off power and gas, remove the panel, disconnect the two terminals, and unscrew the limit from its mounting. Confirm the 150°F rating and disc length match the original before installing. Always correct any airflow restriction that caused a trip.\u003c\/p\u003e\u003cp\u003eGenuine Goodman quality.
