Welcome to the forum
Not sure who you talked to at the factory, but the gap between the upper cooling coils and the outside wall is somewhat critical in the proper operation of the cooling unit. If you have the paperwork, look for the installation instructions and it should have a drawing with clear measurements. If the fan is running all the time, then the thermoswitch may be defective.
