About the Course:

This De-Icing the Evaporator Fan Motor microcredential trains HVAC technicians to safely identify, diagnose, and remove ice buildup that affects evaporator fan motor performance in refrigeration and HVAC systems. Learners will practice inspecting airflow restrictions, recognizing signs of ice accumulation, and determining the causes of icing-related issues.

The course also covers safe de-icing procedures, component inspection, and verification of proper fan operation after maintenance. Emphasis is placed on safe work practices and system restoration techniques to ensure efficient cooling performance, reliable operation, and prevention of future icing problems.

Learning Objectives:

  • Identify symptoms of evaporator fan motor icing, including reduced airflow and cooling inefficiency
  • Safely shut down and isolate HVAC equipment before maintenance
  • Inspect evaporator sections for ice buildup and airflow obstructions
  • Determine common causes of icing, including restricted airflow and system operating conditions
  • Perform safe de-icing procedures using approved methods
  • Inspect the evaporator fan motor and surrounding components for damage
  • Restore system operation and verify proper airflow and cooling performance

 

Course delivered via LMS and requires an Oculus VR headset for hands-on VR simulations.
