OEM Lennox Scroll Compressor 44,200 BTUH 380V 3-Phase — 98W54

The genuine OEM Lennox 98W54 is an Interlink ABA042DBA scroll compressor rated at 44,200 BTUH (roughly 3.5 tons), designed for 380V (max), 3-phase, 22–60 Hz, R-410A applications. This compressor is the core component of your Lennox outdoor unit, compressing and circulating refrigerant to move heat out of the conditioned space. The scroll mechanism provides smooth, efficient compression with fewer moving parts for long service life.

Common failure symptoms: A failing 98W54 may present as a compressor that hums but won't start, repeatedly trips the breaker, produces little or no cooling, runs excessively hot, or makes rattling and metallic noises. Electrical faults such as shorted, open, or grounded windings and mechanical seizure all point to compressor replacement.

Why OEM matters: The 380V 3-phase, wide-frequency design of the 98W54 is matched precisely to the Lennox systems it serves. Using the factory-specified part ensures correct voltage tolerance, capacity, and oil charge, preserving rated efficiency and your equipment warranty. Non-OEM alternatives risk electrical incompatibility and premature failure. Confirm the part against your unit's nameplate, pull a proper vacuum, replace the liquid-line filter drier, and recharge to Lennox specifications during installation.
