This normally-closed thermal switch mounts near the blower\/heat-exchanger area and opens the control circuit if temperatures rise beyond safe limits — for example during blower failure or restricted airflow — shutting down the burners to prevent overheating and heat-exchanger damage. The light-blue body color identifies its specific trip temperature, so matching the exact part is essential.\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 high-limit safety switch (light blue code)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAction:\u003c\/strong\u003e Normally closed; opens on overtemperature, auto-resets on cooldown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman \u0026amp; Amana DMP125-52AB furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Overheat protection \/ burner safety cutout\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e Limit switches are calibrated to a precise trip temperature indicated by the color code. The OEM 0130F00038 guarantees the correct set point and mounting footprint. A generic switch with the wrong rating can either nuisance-trip or fail to protect the furnace — a genuine part is the safe choice for any safety control.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty:\u003c\/strong\u003e ⭐ Easy. Usually two mounting screws and two push-on terminals. Cut power first, note wire positions, and swap. Verify normal cycling after install. If the old switch tripped, diagnose the airflow\/blower cause before returning the unit to service.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058019713395,"sku":"GOODMAN-9532","price":8.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-auxiliary-limit-switch-lt-blue-for-dmp125-52ab-0130f00038","provider":"National HVAC Parts","version":"1.0","type":"link"}
