{"product_id":"oem-lennox-scroll-compressor-4-5-ton-575v-3-phase-19a08","title":"OEM Lennox Scroll Compressor 4.5 Ton 575V 3-Phase — 19A08","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e19A08\u003c\/strong\u003e is a ZP51K6E-TFE scroll compressor rated at 4.5 tons for 575V 3-phase applications. As the heart of your Lennox condensing unit, this compressor circulates and pressurizes refrigerant to move heat out of the conditioned space — without it, the system cannot cool. Its scroll design delivers quiet, high-efficiency operation with fewer moving parts than reciprocating units.\u003c\/p\u003e\u003cp\u003eCommon signs of compressor failure include the outdoor unit humming but not starting, tripped breakers, loud grinding or rattling noises, warm air from the supply vents, and short cycling. Electrical failures often show as a burnt smell or a compressor that draws locked-rotor amps and shuts down on overload.\u003c\/p\u003e\u003cp\u003eChoosing the OEM \u003cstrong\u003e19A08\u003c\/strong\u003e matters because Lennox systems are engineered around specific compressor displacement, oil charge, and electrical characteristics. An exact factory replacement preserves rated capacity, SEER efficiency, and warranty coverage, and guarantees correct fit with your existing line set, contactor, and controls.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081085305203,"sku":"LNX-19A08","price":389.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-scroll-compressor-4-5-ton-575v-3-phase-19a08","provider":"National HVAC Parts","version":"1.0","type":"link"}
