Detailed information about this program

Thermo King Level One is a combination of two certifications that focuses on the explanation of transport refrigeration and the basic components of refrigeration. Students will understand the different types of units Thermo King services and represents. This certification will provide a valuable, stackable credential that can be easily embedded into a Diesel and/or HVAC/R curriculum. A student with a Level One certification will provide the base level skills and knowledge regarding maintenance and operation of Thermo King equipment. Students learn the scope and purpose of the transport refrigeration industry, operating modes of a Thermo King single temperature trailer unit, operation of the four main components of a refrigeration system, refrigerant flow and component interaction, refrigeration equipment and procedures, proper service procedures (refrigerant level check, low side pump down, refrigerant recovery, evacuation and charging), Thermo King SR4 Transport Refrigeration Control interface and alarm codes, and preventative maintenance procedures (batteries, trailer inspection, engine, coolant tank and lines, air intake system, belt condition).

What You'll Learn

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.
