Supplied as a complete kit for correct installation, it is engineered to Lennox heat pump specifications so your system reliably changes modes and maintains proper refrigerant charge and pressure.\u003c\/p\u003e\u003cp\u003eA malfunctioning reversing valve often shows up as a heat pump stuck in one mode — blowing cold air in heating season or warm air in cooling season — failing to change over on demand, a loud hissing or clunking during mode transitions, or inconsistent temperatures throughout the home. A stuck or leaking valve can leave the system unable to satisfy the thermostat at all.\u003c\/p\u003e\u003cp\u003eChoosing the OEM \u003cstrong\u003e49W64\u003c\/strong\u003e kit matters for Lennox equipment because reversing valves are matched to the system's refrigerant type, capacity, and solenoid control circuit. A factory kit ensures correct port sizing, leak-free connections, and full compatibility with Lennox controls — critical for restoring proper heat pump performance and protecting the compressor.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081133080947,"sku":"LNX-49W64","price":59.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-solenoid-valve-reversing-LNX-49W64.jpg?v=1783763383","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-reversing-valve-kit-49w64","provider":"National HVAC Parts","version":"1.0","type":"link"}
