When the sensing element reaches the trip threshold, the switch opens the control circuit and holds it open until a technician manually resets it at the unit. This design prevents the system from restarting automatically after a high-limit event, making it a safety-critical component in forced-air heating systems. Licensed HVAC technicians handle installation and replacement of this switch as part of routine service or fault diagnosis.\u003c\/p\u003e\n\u003cp\u003eThis limit switch is used in residential and light-commercial forced-air heating applications where a manual reset safety device is required at the 190 degrees F trip point. It is installed in the heat exchanger compartment or plenum area of a gas furnace or air handler. Typical scenarios include warranty replacement, field failure diagnosis, or scheduled preventive maintenance on older equipment. The switch is supplied by Wako Electronics and was catalogued under GOODMAN part 10123537 as an accessory-class component in the switches product family.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eManual reset operation requires technician intervention after a high-limit trip, preventing automatic restart\u003c\/li\u003e\n  \u003cli\u003e190 degrees F trip temperature provides defined overtemperature protection for the heat exchanger circuit\u003c\/li\u003e\n  \u003cli\u003eAccessory-class switch designed for integration into furnace or air handler control wiring\u003c\/li\u003e\n  \u003cli\u003eSourced from Wako Electronics, catalogued under GOODMAN part number 10123537\u003c\/li\u003e\n  \u003cli\u003eCountry of origin: Mexico\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style manual reset limit switch replacement for residential and light-commercial gas furnaces and air handlers requiring a 190 degrees F rated safety limit device.

Always shut off electrical power to the unit at the disconnect and set the gas valve to the off position before servicing any limit switch. After installation, verify wiring connections are secure and test the manual reset function before returning the system to operation. Follow applicable local codes and manufacturer service documentation when replacing safety-critical control components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrip Temperature\u003c\/strong\u003e: 190 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReset Type\u003c\/strong\u003e: Manual\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Class\u003c\/strong\u003e: Switches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit Type\u003c\/strong\u003e: Accessory\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Mexico\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVendor\u003c\/strong\u003e: Wako Electronics\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: GOODMAN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10123537\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GOODMAN","offers":[{"title":"Default Title","offer_id":51138745205042,"sku":"10123537","price":35.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305533628.png?v=1778262886","url":"https:\/\/voomisupply.com\/products\/goodman-10123537-manual-reset-limit-switch-190f","provider":"Voomi Supply","version":"1.0","type":"link"}
