This normally-closed thermal switch monitors temperature at the burner\/heat-exchanger area and opens the ignition circuit if it senses an overheat or flame-rollout condition. When it trips, the furnace won't fire until the fault clears — protecting the heat exchanger and household from unsafe operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0130F00038\u003c\/li\u003e\n\u003cli\u003eIdentifier: Light-blue trip color coding\u003c\/li\u003e\n\u003cli\u003eType: Auxiliary \/ rollout thermal limit, normally closed (auto-reset)\u003c\/li\u003e\n\u003cli\u003eCompatibility: Amana\/Goodman AMH80403AXBD and related 80% furnaces\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (Amana family)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are calibrated to a specific trip temperature and reset point. The OEM 0130F00038 carries the exact factory rating and the correct color code, so replacement matches the original protection curve. Substituting a generic switch with a different trip point can cause premature nuisance trips or, worse, fail to protect against a genuine overheat — never guess on a safety cutout.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2\/5).\u003c\/strong\u003e Disconnect power, note the wire positions, remove the mounting screws, transfer the spade connectors to the new switch, and remount — about 10–15 minutes. If the switch keeps tripping after replacement, investigate the root cause (blocked flue, dirty burners, or failing inducer) rather than bypassing it. When in doubt, use a licensed HVAC technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057601462643,"sku":"GOODMAN-4991","price":5.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-auxiliary-limit-switch-for-amh80403axbd-0130f00038","provider":"National HVAC Parts","version":"1.0","type":"link"}
