This switch monitors refrigerant pressure on the low side of the refrigeration circuit and interrupts system operation when pressure drops below a safe threshold, protecting the compressor from damage caused by low refrigerant charge or loss of charge conditions. It is a direct replacement part intended for installation by licensed HVAC technicians servicing Carrier equipment. The compact form factor and OEM specification ensure proper fit and reliable electrical performance in the system.\u003c\/p\u003e\n\u003cp\u003eThis low pressure switch is used in residential and light commercial HVAC applications where refrigerant circuit protection is required. It is typically found in split-system air conditioners and heat pumps, mounted in the low-pressure side of the refrigerant circuit between the evaporator and the compressor. Technicians replace this switch when system diagnostics indicate the existing switch has failed open or closed, when pressure lockout faults are logged, or when the switch tests out of spec during a refrigerant circuit inspection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGenuine OEM Carrier replacement part for assured fit and function\u003c\/li\u003e\n  \u003cli\u003eMonitors low-side refrigerant pressure to protect the compressor\u003c\/li\u003e\n  \u003cli\u003eOpens circuit on low-pressure condition to prevent compressor damage\u003c\/li\u003e\n  \u003cli\u003eCompact 1 inch x 1 inch x 1 inch body fits tight equipment compartments\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.5 pounds for easy handling during service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement low pressure switch for Carrier HVAC refrigerant systems. Consult Carrier OEM documentation or cross-reference the part number 17400516000850 against your equipment model to confirm fitment before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician holding the appropriate EPA Section 608 certification for refrigerant handling. Before replacing this switch, recover refrigerant per EPA regulations, de-energize the system at the disconnect, and verify zero voltage with a meter before handling any wiring. Do not over-torque the switch fitting or use thread sealants not approved for refrigerant service. After installation, leak-check the connection point, recharge the system to manufacturer specification, and verify proper pressure switch operation before returning the equipment to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: CARRIER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17400516000850\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARRIER","offers":[{"title":"Default Title","offer_id":51138633335090,"sku":"17400516000850","price":29.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532059.webp?v=1778260741","url":"https:\/\/voomisupply.com\/products\/carrier-17400516000850-low-pressure-switch-hvac","provider":"Voomi Supply","version":"1.0","type":"link"}
