Designed specifically for the higher operating pressures of R-410A refrigerant, this compressor drives the refrigeration cycle in your Lennox condensing unit and delivers efficient, quiet scroll operation. It is the correct replacement for modern R-410A Lennox equipment that cannot use legacy R-22 compressors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e loss of cooling, tripped breakers or internal overload, loud mechanical noise on startup, hard-starting or failure to start, abnormally high or low suction\/discharge pressures, and grounded or open windings. R-410A units running low on charge or with restricted airflow accelerate compressor wear.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e the 28W85 is engineered to Lennox's exact R-410A capacity, oil (POE), and electrical requirements. Using the OEM compressor maintains warranty eligibility and ensures the correct pressure envelope for R-410A operation — critical because R-410A runs roughly 50–70% higher pressures than R-22. Substitute parts risk oil incompatibility and dangerous over-pressure. Replace the filter drier, evacuate to a deep vacuum, and verify charge to nameplate before startup.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081117647219,"sku":"LNX-28W85","price":389.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-r-410a-scroll-compressor-51-500-btuh-230v-28w85","provider":"National HVAC Parts","version":"1.0","type":"link"}
