It opens the control circuit at 140 degrees F and resets automatically when the temperature drops to 110 degrees F. This type of limit switch is a direct safety device in the furnace control circuit, interrupting burner operation when airflow is insufficient or temperatures exceed safe thresholds. Licensed HVAC technicians install this component as part of routine furnace service or as a direct OEM-style replacement when the existing switch has failed or is reading out of calibration.\u003c\/p\u003e\u003cp\u003eThis limit switch is suited for residential gas furnace applications where the heat exchanger or plenum temperature must be monitored and controlled. It mounts in the furnace cabinet near the heat exchanger or supply plenum and is wired into the low-voltage or line-voltage control circuit depending on furnace design. It is a common service replacement in forced-air heating systems where overtemperature faults are causing nuisance shutdowns or where the original limit switch has tested open at ambient temperature.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOpens at 140 degrees F to interrupt burner operation and prevent heat exchanger damage\u003c\/li\u003e\n\u003cli\u003eCloses at 110 degrees F for automatic reset when safe temperatures are restored\u003c\/li\u003e\n\u003cli\u003eOEM part number 025-29041-005 ensures direct factory-specification fitment\u003c\/li\u003e\n\u003cli\u003eDesigned for gas furnace safety control circuits\u003c\/li\u003e\n\u003cli\u003eCompact limit switch form factor for standard furnace cabinet mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement limit switch for YORK residential gas furnace systems.

Before servicing, shut down the furnace completely and disconnect electrical power at the disconnect or breaker. Verify the replacement switch orientation and terminal connections match the original before energizing the system. After installation, cycle the furnace and confirm normal high-limit operation using a calibrated thermometer or HVAC service analyzer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Temperature\u003c\/strong\u003e: 140 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClose Temperature\u003c\/strong\u003e: 110 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: High-Limit Safety Switch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: YORK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 025-29041-005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"YORK","offers":[{"title":"Default Title","offer_id":51468234391858,"sku":"025-29041-005","price":26.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313946065.jpg?v=1783915328","url":"https:\/\/voomisupply.com\/products\/york-025-29041-005-limit-switch-140f-open-110f-close","provider":"Voomi Supply","version":"1.0","type":"link"}
