It functions as a high-limit safety device, monitoring heat exchanger temperature and shutting off the burner when temperatures exceed the set threshold. The switch features a 110 to 140 degrees F operating range and a 7 inch insertion depth, making it sized for typical residential and light commercial gas furnace heat exchanger compartments. Auto-reset operation returns the switch to normal function once temperatures fall back within safe range. Installation is performed by licensed HVAC technicians as part of routine service or safety-device replacement.\u003c\/p\u003e\n\u003cp\u003eThis limit control switch is a direct replacement component for the BARD NCH080D48A and NCH095D60A gas-fired furnace models. These are packaged heating units commonly found in commercial and light-duty applications. The switch mounts into the furnace cabinet and monitors temperatures within the heat exchanger section, providing automatic over-temperature protection to prevent equipment damage and maintain safe operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e110 to 140 degrees F operating range for over-temperature protection\u003c\/li\u003e\n  \u003cli\u003e7 inch insertion depth sized for gas furnace heat exchanger installation\u003c\/li\u003e\n  \u003cli\u003eAuto-reset function restores normal operation after cool-down\u003c\/li\u003e\n  \u003cli\u003eOEM-specified replacement for BARD NCH080D48A and NCH095D60A furnaces\u003c\/li\u003e\n  \u003cli\u003eSafety shutoff cuts burner operation on over-temperature condition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSpecified for use on BARD NCH080D48A and NCH095D60A gas-fired furnace models.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Shut off gas supply and disconnect electrical power to the furnace before removing or installing any limit control device. Verify insertion depth and mounting orientation match the original component before securing. Consult applicable local mechanical codes and the IFGC for service requirements on gas-fired heating equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Limit Control Switch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: 110 to 140 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReset Type\u003c\/strong\u003e: Auto\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsertion Depth\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.036 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BARD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8402-064\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BARD","offers":[{"title":"Default Title","offer_id":51283895877938,"sku":"8402-064","price":29.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278046.png?v=1781062636","url":"https:\/\/voomisupply.com\/products\/bard-8402-064-furnace-limit-control-switch-110-140f","provider":"Voomi Supply","version":"1.0","type":"link"}
