I just finished my aquarium temp controller about 10 minutes before I found this thread. Seriously.

The thermostat unit on my magic chef just popped out of the front of the freezer. Once I pulled it out it was pretty easy to find the adjustment screw. Like Assistant Brewer mentioned, it was covered by a sticker.

That's good! Use that for fermentation and use this for kegs!

I actually used this method on a cheap kegerator I bought at Home Depot. I was having an issue with it not getting cold enough. Did a little research and found this same method on the MicroMatic forums. Just took the thermostat off, gave the screw a couple turns, and made a big difference.

Update: everyone should give this a try if they're building a keezer. I finished my collar up over the weekend and since Saturday the temp has been holding steady at about 39-40 degrees with just the thermostat adjustment described by assistant brewer. No external temp controller!

Default am I screwed?

So, after some searching, I found the screw that assistantbrewer was talking about. I tightened it some, no change. i loosened it some, no change. So i loosened it some more, then some more, then the screw came out completely!

I can see the spring mechanism swinging freely inside the "box" or relay or whatever. I can't seem to get the screw to catch the spring and so can't get the screw to tighten again. It seems like the freezer will still run even with the internal temp at 30 F.

Am I totally screwed? Is there any way to fix this? If so, can I assume that loosening the screw is not the right direction (since it is completely out and the freezer is still running at 30 F)? Any advice would be appreciated.

Of note to others - be careful how much you loosen this screw - apparently it can come out!

I'm confused... how long did you wait after turning the screw once, before you turned it the second time? And similarly, how long did you wait after that before turning it a third time?

This is an awesome thread, just got a chest freezer today for free from a friend, was about to order an external and then I saw this. Thanks for the info!

I was doing what assistantbrewer described in post # 17 of this thread - compressor off and freezer unplugged, then started turning the screw waiting for the compressor to click on. I never heard the click, but maybe it was just quiet or subtle and I missed it. I am going to have to work on it some again tonight. I can see where the screw needs to go, but I am not sure I can get it to screw back in again.
