Adjust temperature control in German Liebherr Kegerator

Hey guys - this is my first post but not my first time homebrewing! I've got a question concerning a truly German kegerator that I bought off of a truly German man. It uses a power converter to go from the european plugs to north american plugs. It works great but...

Here's the deal - I want to use my kegerator as a temperature controlled environment sometimes for fermentation but my warmest setting is still too cold (62°F - soo close!). I can't find the kegerator model or anything but it's a turn knob - 1 through 7 - that controls the temperature. I tried taking the knob off to see if there was an adjusting screw but no luck. If I get some responses, I can post a pic using an image hosting service (I'm a n00b on here so I don't get to post images yet).

Does anyone have any ideas? I'd really appreciate any kind of advice! Thanks.

At 62f your beer will be fermenting at several degrees higher which is perfect for most ales.

Unfortunately, the temperature is like 60, making my beer 62°F. Sorry I didn't explain beforehand. My fermometer reads 62°F. I tried taking it apart last night to look at it. I read somewhere about some adjusting screws and so I tinkered with some screws inside the temperature control unit. No luck.

I have pictures to post if anyone cares.
