Default Questions About Converting My 7.2 cu ft Fridge to a Fermentation Chamber

I have a 7.2 cu ft fridge I am converting to a fermentation chamber. I am looking for advice from anyone who knows anything about this process or has gone through it themselves.


I have 2 objectives:

1. Temperature control.

Option A: Purchase a Johnson Controls thermostat (such as http://www.northernbrewer.com/brewing/brewing-equipment/fermenting-equipment/fermentation-temperature-control/johnson-controls-a419-digital-temp-controller.html)

Option B: Using the current wiring of the refrigerator, remove the built-in thermostat and replace it with an external digital thermostat set to my choosing.


Option A seems very easy. In fact, my father works for JC and could possibly find me something very similar to the link above for a fraction of the list price. Of course with this option I have to figure out how to get the temperature gauge into the fridge.

Option B would be awesome because I could easily control the temperature with the digital read out, and it would be far less expensive with just purchasing or finding an old thermostat. Plus it uses the existing wiring so it seems like while it would be more work, it could possibly be less as I don't have to worry about external wires coming from the temperature gauge running into the door or whatever. Anyone have any advice on how to do this? I feel like this would be my first choice if I could pick one of these two, but it also has the larger chance for screwing something up!


2. Removing the built-in freezer

Basically, the fridge looks like this (http://www.google.com/imgres?imgurl=http://images.craigslist.org/3k43mc3l25Y25Z65W0a8u8df6ab4febeb1326.jpg&imgrefur l=http://www.iclassifieds.com/forsale/appliances/600322048/kenmore-refrigerator-dorm-size.html&usg=__GUEi045na9swrTGXpWJV3sziD5g=&h=224 &w=300&sz=6&hl=en&start=0&zoom=1&tbnid=BmBv_k4G KDg OoM:&tbnh=135&tbnw=186&prev=/images%3Fq%3Dkenmore%2B564.9143110%26um%3D1%26hl%3 Den%26sa%3DN%26biw%3D1680%26bih%3D860%26tbs%3Disch :1&um=1&itbs=1&iact=rc&dur=200&ei=B8OeTMacL8b_lgf a 05XtAg&oei=B8OeTMacL8b_lgfa05XtAg&esq=1&page=1&nds p=33&ved=1t:429,r:7,s:0&tx=56&ty=64)

The freezer section is easily removed by unscrewing the coiled section from the top of the fridge. The problem is crimping off the freon tube going to the freezer so that I can remove it completely. I don't want to lose some of the freon and then have a fridge that doesn't work properly.

Is there a real effective way to doing this? Any advice?



Anyone who is familiar with converting a fridge to a fermentation chamber please give me any advice you can.

It's a Kenmore, model # 564.9143110

Thanks

This might help you figure out the wiring...
http://www.homebrewtalk.com/f11/love-temp-controller-series-ts-wiring-diagram-2008-a-88369/ I know its not a JC but it might help you understand how to wire one in.

Also, as far as the existing thermostat, you could just turn it to highest setting so that it always runs whenever the new controller tells the fridge to, or remove it and tie the two wires together.
