This piston-driven compressor pressurizes and circulates refrigerant through your Lennox outdoor unit to drive the cooling cycle. Reciprocating compressors are rugged and well-suited to the operating conditions of legacy R-22 Lennox systems, making the 15R48 the correct drop-in replacement for that equipment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e no cooling or weak cooling, the unit humming without starting, breaker or overload trips, loud knocking from worn valves or bearings, hard-starting, excessive amp draw, and grounded or open windings. Valve plate failure and stuck pistons are common on aging reciprocating units.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e the 15R48 matches Lennox's exact capacity, voltage, and refrigerant specifications for R-22 service. Using the OEM Tecumseh compressor keeps the system properly matched, protects warranty coverage, and avoids capacity or electrical mismatches from generic substitutes. Because R-22 is phased out, verify recovered refrigerant and system condition, install a new filter drier, evacuate the system, and confirm voltage and start components before energizing.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081117712755,"sku":"LNX-15R48","price":389.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-tecumseh-reciprocating-compressor-42-000-btuh-15r48","provider":"National HVAC Parts","version":"1.0","type":"link"}
