How to get a kegerator colder

I have a Kegco K199SS-2 and I can't get it colder than 42 degrees F. Does anyone have any suggestions?

Have the freon checked.

Try blowing a fan across the back coils.

Check for bad seals.

Sorry I don't have an answer for you but I remember a year or so ago people were having the same problem with Danby kegerators. There was a fix that you can do yourself. I've been trying to find on Google. I know you don't have a Danby but I'll bet the same fix will help yours. It is basically making an adjustment (internally) on the thermostat. Somebody here will surely know. I'll keep looking.

Thanks for the help!

Is there some way I can manually adjust my thermostat?

Probably. Assuming it has an electromechanical thermostat (most do) you just need to find the adjustment screw, which is likely hidden. You might find this thread helpful-

I've been manually adjusting it but I haven't gotten it any colder yet. How much should I turn the screw? A 1/4 turn? Thanks for the thread it really helped out.

I got it down to 36. Thanks for all your help!

Why? I have my 3 kegerators at 41° and if I do an a mild brown I set it at 45°. I like to taste my beer not freeze my taste buds

My previous settings would get between 42-48. Now they get between 36-42. I just prefer my beer a little colder I guess.
