Between 30-40% of swapped compressors are found to have no real issue, and these checks will help technicians uncover root-cause issues and potentially avoid costly and time-consuming work that might not be needed. This episode details the five checks: oil level and oil management, compressor superheat, electrical health, operating conditions, and controller/sensor accuracy. We also cover key readings and how to better understand failure modes and prevent repeat failures.
