About the Course:

This Diagnosing and Replacing Transformers microcredential trains HVAC technicians to diagnose, test, and replace control transformers used in heating, ventilation, and air conditioning systems. Through VR simulations and guided diagnostic scenarios, learners will identify transformer failures, perform voltage and continuity tests, and replace faulty components in compliance with electrical safety practices. The course emphasizes proper wiring, grounding, and load verification to ensure safe and efficient system operation.

Learning Objectives:

  • Identify the purpose and function of transformers in HVAC control circuits.

  • Diagnose transformer faults including open windings, shorted turns, and overload conditions.
  • Measure input and output voltages using a multimeter to confirm operation.
  • Follow lockout/tagout (LOTO) procedures before performing electrical service.
  • Safely remove and replace transformers with correct voltage and VA ratings.
  • Verify correct wiring polarity, grounding, and secure mounting during replacement.
  • Test system operation post-installation to confirm proper voltage and circuit functionality.

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