What is a common symptom of a malfunctioning refrigeration system?

A malfunctioning refrigeration system can exhibit several symptoms, indicating that it is not operating as intended. One of the key signs is low pressure in the evaporator, which can suggest issues such as refrigerant leaks or restricted airflow. Additionally, frequent cycling of the compressor may occur due to problems such as overloading or an incorrect refrigerant charge, leading to excessive strain and inefficiency.

Consistent high temperature is another alarming indicator, as it signifies that the system is unable to effectively remove heat from the refrigerated space, possibly due to insufficient refrigerant, compressor failures, or issues with the expansion valve.

Given that all these symptoms point towards potential failures within the refrigeration system, it is accurate to assert that they collectively represent common signs of a malfunctioning refrigeration system. Therefore, selecting an option that encompasses all these issues provides a comprehensive understanding of the typical symptoms to look out for in such circumstances.
