Mounted on the blower housing or heat-exchanger assembly, this normally-closed thermal switch opens the control circuit if the furnace exceeds its safe operating temperature — for example during a blower failure or restricted airflow — shutting down the burners to protect the equipment and your home.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0130F00038\u003c\/li\u003e\n\u003cli\u003eType: Auxiliary high-limit thermal switch (normally closed)\u003c\/li\u003e\n\u003cli\u003eColor Code: Light Blue (temperature-rated identifier)\u003c\/li\u003e\n\u003cli\u003eFunction: Over-temperature safety cutout\u003c\/li\u003e\n\u003cli\u003eFit Type: Direct OEM replacement\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 the light-blue coding identifies that exact rating for the AMVC800804CXAB. Installing a generic switch with the wrong trip point can cause nuisance shutdowns or, worse, fail to protect the heat exchanger. The genuine Goodman part guarantees the correct calibration and mounting footprint.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1\/5).\u003c\/strong\u003e Two mounting screws and two spade terminals. Power off at the breaker, note the wire positions, swap the switch, and reconnect. A 10–15 minute job for most DIYers. If the new switch trips immediately, investigate airflow and blower operation before assuming a bad part.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057853219187,"sku":"GOODMAN-7976","price":12.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-auxiliary-limit-switch-for-amvc800804cxab-0130f00038","provider":"National HVAC Parts","version":"1.0","type":"link"}
