This normally-closed thermal switch opens the control circuit and shuts down the gas valve if it senses excessive temperature — typically caused by restricted airflow, a dirty filter, or a failed blower. When an auxiliary limit trips and won't reset, or stays open, the furnace will not fire, making this an inexpensive but essential replacement.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 0130F00038\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Auxiliary \/ rollout-area thermal limit switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor code:\u003c\/strong\u003e Light blue (temperature-rating identifier)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAction:\u003c\/strong\u003e Normally closed, opens on overtemperature, auto-reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman\/Amana AMS80805CXAD and compatible 80% AFUE furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e 1\/4 in. spade terminals\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e Limit switches are color-coded to a specific open\/close temperature. This OEM part carries the exact trip point Goodman specified for the AMS80805CXAD heat exchanger. Substituting a generic switch with a different rating can defeat the furnace's overheat protection or cause nuisance shutdowns — always match the OEM temperature spec.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty:\u003c\/strong\u003e Easy (1\/5). Kill power to the furnace, note the wire positions, remove two mounting screws, transfer the spade connectors, and mount the new switch. A five-minute job with a nut driver. Confirm the blower and filter are clean so the new switch isn't tripped by an underlying airflow problem.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057704485235,"sku":"GOODMAN-7026","price":5.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-auxiliary-limit-switch-for-ams80805cxad-0130f00038","provider":"National HVAC Parts","version":"1.0","type":"link"}
