Refrigeration technicians need to possess patience. Patience is vital for all aspects of a technician's job. It is required while maintaining, repairing, and installing equipment, and even while troubleshooting systems. Patience is definitely a plus while troubleshooting. It's easy for a tech- nician to rush to early conclusions, which may lead him to incorrectly diagnose a system problem. Many times a system must be thoroughly inspected before the tech can determine the root cause. This may include measuring the system's suction and discharge pressures, evaporator and system superheat values, the amount of subcooling at the outlet of the condenser, and perhaps some other system conditions. Measuring these values may take time, but the process should not be skipped — or, worse still, you should not assume (guess) the values.
