OEM Lennox Scroll Compressor 20,300 BTUH R-410A 3-Phase — 98W52

The Lennox 98W52 is a genuine OEM Interlink APA020DA scroll compressor rated at 20,300 BTUH, designed for R-410A refrigerant on a 3-phase, 380V (max) power supply operating across a 22–60 Hz range. As the heart of your Lennox condensing unit, this compressor pressurizes and circulates refrigerant through the system — driving the entire cooling cycle. Its scroll design delivers quieter, more efficient operation with fewer moving parts than reciprocating compressors, which translates to longer service life and steadier performance.

Common failure symptoms: A failing compressor often shows up as warm air from the vents, a unit that hums or clicks but won't start, tripped breakers, hard-starting, loud grinding or rattling noises, or a system that short-cycles. Internal electrical shorts and locked rotors are frequent end-of-life failures.

Why OEM matters: The 98W52 is engineered to Lennox's exact displacement, electrical, and refrigerant specifications. Installing a genuine OEM compressor ensures correct capacity matching, protects your warranty, and avoids the premature failures common with generic substitutes. Always verify the model, voltage, and refrigerant type against your unit's rating plate before installation, and have a licensed HVAC technician perform the replacement and evacuation.
