Generating 30 millivolts (mV) from the heat of a standing pilot flame, the thermocouple signals the gas valve to remain open when the pilot is lit and shuts off gas flow automatically if the flame goes out. The universal adapter tip is compatible with screw-in, clamp-in, and push-in pilot burner configurations, making this a single part that covers a wide range of field replacement scenarios without special tooling.\u003c\/p\u003e\n\u003cp\u003eThis thermocouple is intended for use in gas furnaces, boilers, water heaters, and room heaters equipped with a standing pilot and a millivolt-operated gas valve. It is a direct field-replacement part suited for residential service calls and light-commercial maintenance work where the original thermocouple has failed, degraded, or been damaged. The 30-inch lead length provides adequate routing clearance in most standard appliance cabinets.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e30 mV output — compatible with standard millivolt gas valve safety circuits\u003c\/li\u003e\n  \u003cli\u003e30-inch lead length suits most residential appliance cabinet depths\u003c\/li\u003e\n  \u003cli\u003eUniversal adapter tip fits screw-in, clamp-in, and push-in pilot burner styles\u003c\/li\u003e\n  \u003cli\u003eSingle-part solution reduces van stock needed for pilot system repairs\u003c\/li\u003e\n  \u003cli\u003eAutomatic gas shutoff when pilot flame is extinguished\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a universal OEM-style replacement thermocouple for standing-pilot gas furnaces, boilers, water heaters, and room heaters that use a 30 mV millivolt gas valve safety circuit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed gas appliance technician or qualified HVAC-R service professional. Before servicing, shut off the manual gas supply valve and allow the pilot assembly to cool completely. The thermocouple tip must be fully seated in the pilot bracket clip or threaded fitting, and the connection nut at the gas valve should be finger-tightened then snugged with a wrench — do not overtighten. Verify pilot flame engulfs the thermocouple tip at least 3\/8 inch after reassembly and confirm proper gas valve response before returning the appliance to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Voltage\u003c\/strong\u003e: 30 millivolts (mV)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Length\u003c\/strong\u003e: 30 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdapter Type\u003c\/strong\u003e: Universal (screw-in, clamp-in, push-in)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.175 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\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: RESIDEO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CQ100A1039\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RESIDEO","offers":[{"title":"Default Title","offer_id":51344032661810,"sku":"CQ100A1039","price":20.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310551507.jpg?v=1782027521","url":"https:\/\/voomisupply.com\/products\/resideo-cq100a1039-universal-thermocouple-30mv-30-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
