CAROCertified Assistant Refrigeration Operator Certification Exam

Certified Assistant Refrigeration Operator (CARO) Refrigeration technicians working CARO certification routes daily spend time diagnosing compressor failures, calibrating pressure controls, and replacing worn gaskets on commercial units. You’ll transition from shadowing experienced operators to independently managing routine maintenance logs, responding to temperature alarms, and performing basic component repairs—the foundational tasks that keep walk-in coolers and industrial chillers running without costly downtime interruptions.
