Refrigeration Diagnostics and Service Procedures 2/10/24, 8:30-11:30 am Class #129, DeVos River Overlook D Designed for technicians with prior understanding of the refrigerant cycle and system operation, this three hour seminar will provide technicians with techniques and strategies required to isolate the root cause and perform repairs of failures in R-134a and R-1234yf equipped Air Conditioning (AC) systems. The use of pressure, temperate, and humidity readings as a diagnostic aide will be the foundation of the course. Specific component diagnosis includes variable displacement compressors, electrically driven compressors, expansion valves, Internal Heat Exchangers (IHX), enhanced evaporators and condensers. This course will include simulated diagnostic exercises to apply the principles learned. Presented by: ACDelco Speaker: Rob Roth
