OEM Lennox Scroll Compressor 90,500 BTUH 460V R-410A — 55W35

The genuine OEM Lennox 55W35 is a Copeland ZP90KCE-TFD-950 scroll compressor rated at 90,500 BTUH, running on 460V, 3-phase power with R-410A refrigerant. It serves as the core of your Lennox outdoor unit, compressing refrigerant vapor to move heat out of the conditioned space. The scroll mechanism provides smooth, energy-efficient compression with fewer moving parts and lower noise than reciprocating designs.

Common failure symptoms: Watch for a system that won't cool, a compressor that hums but won't start, repeated breaker trips, loud grinding or rattling, hard starting, or an outdoor unit that runs hot without lowering indoor temperatures. These often point to shorted windings, a locked rotor, or a failed internal overload.

Why OEM matters: The 55W35 is engineered to Lennox's exact capacity, voltage, and refrigerant specifications, ensuring a proper match to your system's metering and electrical components. Choosing this genuine part preserves rated efficiency, protects your equipment warranty, and reduces the risk of comeback failures seen with aftermarket compressors. Confirm the 460V, R-410A rating matches your unit and use a qualified technician for installation.
