I see this available online for a reasonable price. How many 5 gal kegs can you store in this? Also have you tried fermenter buckets or carboys in it? Room for a 5# co2 tank?

I just picked up (free) an older Amana chest freezer. Not sure of the year, but here is some info:



It's got to be 10-15 cf as I can easily fit 6 corny kegs, 5lb CO2 tank and probably a 30 pack inside. Cleaned it up and plugged it in and it works great. I dug into the thermostat hoping to find a coarse adjustment screw and found this:



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.

I'm at the very beginning of my conversion right now. I have read in other topics that you can fit three 5gals on the floor and possibly 2 more on the compressor hump(depending on how tall you make your collar.)

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!

So, after much work, I was able to get the screw back into the spring, but I had to take the controller box completely apart to do it. Unfortunately I now cannot get it back together, because there is too much tension on the back end, were the probe that goes into the freezer attaches. The thing is completely FUBAR. Damn!

After looking at mine in detail from the inside, clearly turing the screw clockwise (making it tighter) would be the right way to turn it, and this seems consistent with what others are saying. So, if you're going to try this, try tightening the screw first. Only loosen it if you are sure that tightening it is the wrong way.

Oh well, instead I let my fridge warm up, and then plugged it into an appliance timer. I've found that If I let it run for 15 minutes, it will bring the temp down from about 50 F to about 40 F. If I let this run twice a day for 15 minutes, it seems to keep it nicely in 40s. Not perfect, but I have a Johnson temp controller that I will use most of the time, and will only use the timer when I am fermenting something (using a heat wrap and the johnson for this part).

Thanks to the OP for posting! This saved me the cost of a temp controller so i figure I'd post how I got mine working.

Just bought a GE 7cuft Freezer Model FCM7DUAWW.


Shot of the Thermostat:


I unscrewed the side vent and pushed in the clips to pop out the themostat.


Once the themostat was dangling out I found the set screw. In this pic it's the top screw in that oval on the side.


It took around an entire week to get the temperature set high enough. I first turned freezer to the warmest setting. Then I screwed the set screw in(clockwise) 3 turns, let the temp stabalize over night. Repeated that over several days. Eventually I got to a total of 11 turns and the freezer temperature was sitting at 48 degrees F at the warmest setting. I wanted the temp down around the upper 30's so I put the thermostat back into the freezer and used the front dial, raising the setting up(cooler) little by little to adjust the temp a little cooler. It didn't take much and I got the temp down to 38 degrees F when the dial was at the 1.5 setting.

It takes some time and patience to get the temperature correct since the freezer has to adjust temperature overnight. But if you take your time and let the temp adjust lowering it little by little then it can be done. =)

Goodluck and Cheers!

I will try this today. I got a GE chest freezer model: fcm7hdnawh

I am not home to check it out, but if anyone has tried it on this model let me know if it worked!

My freezer is swinging widely, 30's to 50's... I ended up going back to my controller to keep it tighter.. It could be because its in my hot garage?

The ambient temp may be a problem. Mine is inside our air conditioned house and only swings maybe 5 degrees at most.

I'd be interested in what kinds of temp swings this translates into for the beer itself. I suppose it might be different for one gallon vs. five, but were these readings with a probe suspended in the air?
Also, have you taken readings the same way with while using your external controller t-stat to see what kind if swings it shows?
