My U-Line beverage cooler is indicating an E5 error code and the unit will not get cold. What is this telling me?
I am not familiar with this unit but in guessing but I would not assume the thermistor is bad, actually if as you say the compressor is running that is all the thermistor can do. My first guess is the condenser needs cleaning, that is the area where it gets warm. If that is clean then the possibility of a refrigerant leak is there. If not that then the compressor most likely has a bad valve in it. I would suggest contacting a refrigeration tech after everything has been cleaned and it still does not cool.
