I was called to a home to repair a refrigerator that was not cooling. Upon arrival, I found that the unit was unplugged. I tested all the functions and found that the compressor was working properly. After a safety delay, the compressor kicked on and the voltage was correct where it needed to be. The racks began to cool, but I advised the customer to give the unit 24 hours to cool completely. If the unit did not cool, it would need to be run through a leak diagnosis.
