Mounted on the heat-exchanger\/burner bulkhead, this primary high-limit is the furnace's main overheat protection: if plenum temperature climbs past the setpoint — usually from restricted airflow such as a dirty filter, closed registers, or a failing blower — it opens the circuit to shut off the burners and prevent heat-exchanger damage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip temperature:\u003c\/strong\u003e 160°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary high-limit safety switch (auto-reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Shuts down burners on heat-exchanger overheat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e OEM replacement for Goodman\/Amana AMH80703ANAA furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e B1370187\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The primary limit governs whether the furnace can safely produce heat. The OEM B1370187 is set to Goodman's precise 160°F trip point and matches the original mounting flange and insertion depth. A generic switch with the wrong rating or geometry can cause short-cycling on limit or, worse, allow unsafe temperatures. OEM is the recommended choice.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty:\u003c\/strong\u003e Easy (DIY-friendly). Cut power to the furnace, unplug the two spade terminals, remove the mounting screws, and install the replacement with the same orientation and probe depth. If the limit was tripping, replace the air filter and verify blower airflow before returning to service.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057610015091,"sku":"GOODMAN-5269","price":10.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-160-f-primary-limit-switch-for-amh80703anaa-b1370187","provider":"National HVAC Parts","version":"1.0","type":"link"}
