1560-460 Compressor VSH170AGANA Scroll is the factory-fitted 3-phase Scroll compressor (VSH170AGANA) for Classic Series and ESP Plus residential and commercial split ducted systems, compressing R410A refrigerant to drive the system's heating and cooling cycle at the heart of the outdoor unit. A failed compressor causes complete system shutdown -- neither cooling nor heating is available until a replacement compressor is installed. Isolate power and recover all refrigerant before replacement -- compressor replacement must be performed by an ARCtick-licensed refrigeration technician.
