This compressor drives the refrigerant cycle in international and export-spec Lennox equipment, compressing low-pressure vapor into high-pressure gas so heat can be rejected at the condenser. The scroll mechanism delivers high efficiency, low vibration, and reliable three-phase performance in demanding commercial and light-commercial applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e Watch for a system that runs but no longer cools, tripped overloads or contactors, phase-related buzzing without startup, abnormal noise, excessive heat, or high amp draw. Loss of compression, shorted or open windings, and mechanical seizure are common causes of replacement in three-phase compressors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The \u003cstrong\u003e49L29\u003c\/strong\u003e is built to exact Lennox factory specifications for the R-407C refrigerant blend, 50 Hz operation, and three-phase electrical requirements — details that generic substitutes frequently get wrong. Installing the genuine OEM compressor guarantees rated capacity, correct oil charge, and long-term reliability while preserving equipment warranty coverage. Confirm voltage, phase, and refrigerant on your unit's data plate before ordering.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081117942131,"sku":"LNX-49L29","price":389.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-scroll-compressor-34-900-btuh-r-407c-49l29","provider":"National HVAC Parts","version":"1.0","type":"link"}
