Covers procedures used to diagnose electrical, control, mechanical and refrigeration problems common to cooling systems. Familiarize students with using the refrigeration cycle and temperature/pressure charts as diagnostic tools in troubleshooting refrigeration system problems. Include various methods of checking refrigerant charges, methods for charging air conditioning and refrigeration systems, electrical and refrigeration system components, and schematic and pictorial diagrams. Upon completion, participants will test for EPA 608 certification.Note: Miscellaneous cost includes certification exam fees.
