Program Details

Detailed information about this program

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).

Key competencies developed through this program

Auto-populated·from NSX Competency Framework

Mastery: developing (Level 2)(based on Certification)

  • Hand tools, pneumatic wrenches, and welding equipment — select and operate with limited oversight to complete scheduled repairs on medium-duty diesel trucks.
  • Brake systems, wheel bearings, and steering mechanisms — inspect and evaluate independently against manufacturer specifications during scheduled preventive maintenance visits.
  • Hydraulic hoists and floor jacks — position and operate without direct supervision to safely raise buses and heavy equipment in a busy fleet shop.
  • Brake relining, wheel alignment, and bolt torquing — adjust and complete reassembly to specification across a range of commercial vehicle models encountered in daily workflow.
  • Motor analyzers and chassis diagnostic charts — connect and interpret readings to isolate malfunctions on diesel engines with moderate complexity in a fleet maintenance environment.
  • Preventive maintenance intervals — manage and document oil changes, battery load tests, and lubrication cycles for multiple vehicles using facilities management software.
  • Safety guards and critical fasteners — systematically examine and adjust on returning fleet vehicles, escalating findings that exceed acceptable tolerances to senior staff.
  • Diagnostic data from handheld computers and pressure gauges — analyze and cross-reference to narrow probable causes of reported drivability complaints on route buses.
  • Repair timelines and work orders — prioritize and communicate with dispatchers and service writers to ensure on-time vehicle return in a high-volume commercial shop.
  • Troubleshooting findings and repair recommendations — document clearly using word processing and spreadsheet software to maintain accurate vehicle service histories.
