customers complaint is that the refrigerator is not cooling properly. I first began diagnostics on the freezer part of the refrigerator since this was a single cool system. freezer would not get below 24° F. during a further diagnosis I had found the evaporator cooling fan not running. evaporator cooling fan motor ratings were set to operate at 115 volts and 60 HZ tested ac voltage at the fan motor plugins and ratings were above 120 volt AC. replace the customer's cooling fan motor with fan on the truck within stock and tested the unit and everything tested out okay.
