I just bought a remote digital thermometer for my cellar.
I'm a bit concerned that the temperature is about 60 at the top and 65 at the bottom;
the crappy thermometer supplied with the unit was reading about 5 degrees cooler than that.
The cooler is on its coldest setting. The unit is a 2 door Vinotemp E series and it's about 5 years old.
Is there any maintenance required for a unit like this? Does the compressor need to be recharged,
like a car's AC unit, or is it supposed to work for ever like a regular fridge?
