As the heart of your Lennox condensing unit, this compressor circulates refrigerant and provides the compression that drives the entire cooling cycle. Its scroll design delivers quieter, more efficient, and more reliable operation than older reciprocating compressors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e When the \u003cstrong\u003e38M79\u003c\/strong\u003e begins to fail, you may notice the outdoor unit humming or clicking but not starting, tripped breakers, warm air from the vents, loud grinding or knocking noises, or the compressor short-cycling on its internal overload. A locked rotor, open windings, or grounded motor typically means full replacement is required.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Lennox systems are engineered around exact compressor displacement, oil charge, and electrical characteristics. Installing the factory-specified \u003cstrong\u003e38M79\u003c\/strong\u003e guarantees correct capacity matching, proper refrigerant flow, and full compatibility with your unit's controls — protecting your warranty and system efficiency. Aftermarket substitutes can cause capacity mismatches, premature failure, and voided coverage. Always verify the model against your unit's data plate, evacuate and recharge to spec, and replace the filter drier during installation.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081120760179,"sku":"LNX-38M79","price":389.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-scroll-compressor-57-500-btuh-200-230v-3-phase-38m79","provider":"National HVAC Parts","version":"1.0","type":"link"}
