Limit switches monitor temperature conditions inside a furnace or air handler and open the control circuit when a high-temperature threshold is reached, protecting the heat exchanger and downstream components from thermal damage. Once temperatures return to the safe operating range, this switch resets automatically without requiring manual intervention. Licensed HVAC technicians install and replace this component as part of routine furnace service and troubleshooting.\u003c\/p\u003e\u003cp\u003eThis limit switch is suited for residential and light-commercial gas furnace and air handler applications where a flanged airstream-style mounting is specified. The auto-reset function makes it appropriate for systems where nuisance lockouts must be minimized while still providing reliable over-temperature protection. It is typically found in forced-air heating systems as part of the primary safety control circuit operating at low voltage.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAuto-reset operation eliminates the need for manual reset after a high-temperature event\u003c\/li\u003e\n\u003cli\u003eFlanged airstream design for secure, consistent mounting in ductwork or heat exchanger sections\u003c\/li\u003e\n\u003cli\u003eLow-voltage circuit compatibility for integration with standard furnace control boards\u003c\/li\u003e\n\u003cli\u003eFunctions as a primary over-temperature safety device to protect heat exchanger components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement limit switch for RHEEM residential and light-commercial forced-air heating systems requiring a flanged airstream, auto-reset, low-voltage limit switch.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with applicable local codes and the equipment manufacturer's service documentation. Disconnect all power to the unit and allow the heat exchanger to cool completely before removing or installing a limit switch. Verify the replacement switch matches the original mounting configuration and circuit voltage before energizing the system. Inspect wiring connections for corrosion or damage during replacement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset Type\u003c\/strong\u003e: Auto Reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Style\u003c\/strong\u003e: Flanged Airstream\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit Type\u003c\/strong\u003e: Low Voltage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RHEEM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 470015a\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RHEEM","offers":[{"title":"Default Title","offer_id":51383672144178,"sku":"470015A","price":33.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312674817.webp?v=1782603902","url":"https:\/\/voomisupply.com\/products\/rheem-470015a-limit-switch-auto-reset-low-voltage","provider":"Voomi Supply","version":"1.0","type":"link"}
