"Performed diagnostic on the unit. The customer reported that the refrigerator is not cooling. Upon inspection, I found that there is a Freon leak and potential compressor failure. The issue is caused by the refrigerator's age, 23 years old, and lack of maintenance and airflow. To resolve the problem, the following repair is needed: repair the leak and potentially replace the compressor. The total cost for the repair will surpass the cost of a new refrigerator. The customer will get a new unit."
