WI cooler outdoors. 10*10*8 outer diameters. Evap coil Russell AA28-106 B . 1 ton r22 TXV..On a AWG 4520 EXNXC condensing unit the AWG 5520 EXN compressor went bad.I replaced it with an AWG 4520 EXN compressor.(actually I did it twice,because the first new compressor was DOA.(I learned what DOA means today )
the Question is two fold.Why 5520 compressor on a 4420 condensing unit?(It looked like original equipment).
I checked capacities etc.It looks to me that that condensing unit will be okey for that box.But,
Why a high temp unit,even though it gives the capacity for this box? Any downside to it?
