This secondary high-limit is typically mounted on the blower deck or near the coil and cuts power if the cabinet overheats due to restricted airflow — a clogged filter, closed dampers, seized blower, or blocked return. It backs up the main limit and helps prevent heat-exchanger damage from chronic overheating.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip temperature:\u003c\/strong\u003e 120°F (opens on rise)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Auxiliary \/ secondary high-limit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset type:\u003c\/strong\u003e Auto-reset (closes when cooled) unless otherwise specified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e Standard 1\/4\" spade connections\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMS80703AXA and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The B1370155 uses Goodman's exact 120°F calibration and mounting geometry, so it protects at the engineered setpoint and seats flush against the deck for accurate sensing.

A 10–20 minute repair: disconnect power, photograph the wiring, unbolt the old switch, mount the replacement in the same orientation for good thermal contact, and reconnect the terminals. If the original tripped, correct the airflow restriction before restoring operation.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057690263923,"sku":"GOODMAN-6889","price":11.96,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-120-f-auxiliary-limit-switch-for-ams80703axa-b1370155","provider":"National HVAC Parts","version":"1.0","type":"link"}
