Mounted on the heat exchanger or blower deck, it senses supply-air temperature and opens the circuit to the gas valve if the furnace overheats — typically from restricted airflow, a dirty filter, or blower failure.\u003c\/p\u003e\u003cp\u003eThis is an \u003cstrong\u003eauto-reset\u003c\/strong\u003e primary limit rated to trip at approximately \u003cstrong\u003e150°F\u003c\/strong\u003e. When temperatures return to normal, the switch closes automatically and the furnace resumes. A limit that opens frequently indicates an airflow problem that should be corrected before returning the unit to service.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOEM Goodman part number: 20162903\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit switch\u003c\/li\u003e\n\u003cli\u003eTrip temperature: 150°F (approximate)\u003c\/li\u003e\n\u003cli\u003eReset: Automatic\u003c\/li\u003e\n\u003cli\u003eFunction: Over-temperature \/ airflow safety cutout\u003c\/li\u003e\n\u003cli\u003eFits: AMSS960403ANAA and compatible 96% gas furnaces\u003c\/li\u003e\n\u003cli\u003eBrands: Goodman, Amana\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The correct trip temperature and insertion depth are critical to safe furnace operation. This OEM switch matches Goodman's exact 150°F calibration and mounting footprint. Generic switches with a different trip point can cause nuisance shutdowns or fail to protect the heat exchanger. OEM is strongly recommended for limit controls.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty:\u003c\/strong\u003e Easy (1\/5). Cut power to the furnace, unplug the two terminals, remove the mounting screws, and install the replacement in the same orientation. No special tools needed — confirm the airflow issue is resolved before restarting.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057789944179,"sku":"GOODMAN-7522","price":8.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-150-f-primary-limit-switch-for-amss960403anaa-20162903","provider":"National HVAC Parts","version":"1.0","type":"link"}
