Upon inspection, the refrigerator was not cooling as expected. The root cause was identified as a malfunctioning evaporator fan motor. I carefully accessed the internal components, ensuring the refrigerator was disconnected from power for safety. The faulty motor was removed, and a new, high-quality replacement was installed. After reassembling the unit, I tested the refrigerator to confirm proper cooling function. The appliance now operates efficiently, maintaining the desired temperature. The customer was pleased with the resolution and the restored performance of their refrigerator.
