The compressor engages during the defrost cycle to help melt any frost buildup on the evaporator coils. By running the compressor, the system allows refrigerant to flow through the coils, increasing their temperature and facilitating the melting of ice. This process helps maintain efficient operation and ensures optimal heat exchange in the refrigeration system. Additionally, the compressor's operation during defrost helps manage humidity levels by removing moisture from the air.
