Hi, I have a DWC 600ss, need a manual to see how to set the temp as it's not getting cold, could there be a problem with the cooler

I could not find DWC-LD1213 manual. I am sharing the link for same series manuals. It may help you.

set the temp higher,or check front exhaust vent,"a low temp means it is too cold,adjust the thermostat to a warmer temp"

If you got this new, You should have a manual with the hi-est and lowest temp setting in it...If you do not have the manual than you can Google the same question on google search and get a manual,or a forum where they talk about this model.

HI,CHECK THE COOLER TEMP CONTRL ,CHECK THE COMPRESSOR AND CHECK THE EVAP MOTOR ,,ANY OF THIS COMPONENTS MAY BE BAD..GOOD LUCK..

is the link to your manual.Typically in a dual temperature zone wine cooler whites are stored in the bottom and reds on top as whites are better a little colder and the cold air will drop to the bottom of the unit.
Hope this helps!

If compressor is running and it gets hot and the unit does not cool the compressor is bad or you have a leak in the system. if you see oil there's a leak.

not worth repairing , get new

when the fan comes on so does the compressor,hold the fan with a rag and see which one is making the noise-mike

Check your thermostat setting, if the setting is ok then something wrong with your thermostat control.
