Using Blueprints to Troubleshoot a Defective Compressor Motor
By Excelsior College
In this simulation activity, an electrician troubleshoots a defective compressor motor that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.
