There are tiny screws inside the "cut in" and "cut out" holes. I assume if I turn those counterclockwise, it will run warmer? Turn both the same amount? Some insight would be helpful.
Ran out of patience with this freezer and sold it for $50. I now have my eye on a 5 year old Haiar 5cu ft freezer on craigslist. I shouldn't have a problem with this one, I would think.

I wanted to try this out and was wondering where the screw is going to be. I have two little boxes with wires going into them. One on the compressor(first pic), and one all alone(second pic). Which one should i try taking apart? Thanks for the help.

I would say the second pic. Try to find where the thermocouple attaches. In the second pic if that is where the dial attaches to fine tune the temp for normal operations them that is where the course adjust screw is located. Just don't adjust the round dial once you start adjusting the course adjust screw or you might have a hard time fine tuning the temp. Sounds wrong but for some reason for me the normal knob screwed things up for me.

Just want to get another thanks to the OP! I'm pouring brew now pretty consistently at 38 degrees. Saved me at least 50 bucks and some electrical work.

I'm not sure if this changes anything, but the knob in the second pic spins on its own. Seems to be like a timer for the freezer to turn on and off.
