Task H-20 Diagnoses temperature control systems
Task Descriptor
Temperature control systems include refrigeration and propane heating. These units regulate and monitor the temperature of trailer bodies, allowing for the transportation of perishables and temperature-sensitive cargos. Fuel systems, and starting and charging systems are part of the drive mechanism for the refrigeration and compressor units. Special licenses may be required to work on refrigeration and propane heating systems. Transport trailer technicians should have a good working knowledge of these systems for safety purposes. They are expected to be able to diagnose issues with these temperature control systems.
