What could a technician check if a refrigeration system is not cooling properly?

In assessing a refrigeration system that is not cooling properly, it's important for a technician to examine various aspects to identify the root cause. Both duct work sealing and electrical connections play critical roles in the efficient operation of a refrigeration system.

Duct work sealing is essential because any leaks in the ducts can lead to loss of cool air, drastically affecting the system's ability to maintain the desired temperature. If ducts are not properly sealed, cooled air can escape before it reaches the intended areas, resulting in poor cooling performance.

On the other hand, electrical connections are crucial for a refrigeration system's operation. Any loose or faulty electrical connections can hinder the performance of the compressor, fans, or other integral components. If electricity is not flowing as it should due to bad connections, the system may struggle to function correctly, leading to insufficient cooling.

Thus, by checking both the duct work sealing and electrical connections, a technician addresses two significant potential issues that could be affecting the refrigeration system’s cooling efficacy. This comprehensive approach helps pinpoint and rectify problems more effectively, restoring the system back to optimal performance.
