This purple-coded, temperature-activated switch monitors the heat exchanger and shuts off the burners if airflow drops and temperatures climb too high — protecting against a cracked heat exchanger and fire hazard. A failed limit that trips early causes the burners to cut out prematurely; one stuck closed defeats a critical safety function and must be replaced.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0130F00035\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eColor code: Purple (factory trip-point identifier)\u003c\/li\u003e\n\u003cli\u003eAction: Automatic reset on temperature\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMH80403ANAA \u0026amp; compatible furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are calibrated to a specific trip temperature — the \u003cstrong\u003epurple color code\u003c\/strong\u003e denotes that exact setpoint. Genuine OEM guarantees the correct rating; a mismatched generic can trip too early (nuisance shutdowns) or too late (safety risk). For a safety-critical control, always use the factory-matched part.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2\/5)\u003c\/strong\u003e — Two screws and two spade terminals. Cut power first and confirm the replacement's color\/trip rating matches the original. Never bypass a limit switch. Professional service recommended if the limit trips repeatedly, as it may indicate an airflow or heat-exchanger problem.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057599234419,"sku":"GOODMAN-4912","price":22.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-limit-switch-purple-for-amh80403anaa-0130f00035","provider":"National HVAC Parts","version":"1.0","type":"link"}
