Transport Refrigeration - Level 2

Thermo King Level Two is a combination of two certifications that build upon the Level One foundational skills. In Level Two, students will learn about transport refrigeration control systems and advanced refrigeration system diagnostics. This certification will provide a valuable, stackable credential that can be easily embedded into a Diesel and/or HVAC/R curriculum. A student with Level Two certification will acquire the skills and knowledge regarding operation and troubleshooting of Thermo King equipment. Course content includes control system layout of a Thermo King single temperature trailer unit, control component logic (software, microprocessor, relays, FETs and status LEDs), low and high voltage components, refrigeration system data gathering and diagnosis (sequence of operation, alarm codes and temperature differential), inspecting/reviewing external factors (trailer condition, loading practices, airflow, load effect on pull-down time), and refrigeration system troubleshooting (primary and secondary refrigeration symptom analysis, normal operating pressures/temperatures, root cause determination).
