Default prepare your GMR04 4.4CF minifridge for kegs!

I was given a free mini fridge by my dad to take up to school and keep in my room. Its a GE Spacemaker GMR04 with a lock. The lock is fairly useless on it and on first inspection it wouldent make a kegorator because of a small freezer that takes up the entire top of the fridge. But, after a little fiddling, and I mean little, this fridge is great for kegs!

Here you can see the little bugger freezer wont allow a keg to fit in!


so now we get started to mod the fridge.


What you will need:
A screwdriver

THATS IT.



On the back of the fridge there is a diagram showing that the only place there is cooling ('evap') is the freezer, and on the sides of the fridge there are heat disipation coils, nothing on the top of the fridge like the Sanyos to worry about drilling through. So we need to get the evap out of the way.

To remove the little lid for the freezer just pull it out, its plastic and will bend and come right out.
Now there are 4 screws holding the freezer up, remove those, you can put them back in the holes to seal them once we move the freezer later.
Here is a picture of the freezer with the door removed and the screws out, it droops a little, this is fine.


Now, the freezer is still in the way. So we need to CAREFULLY bend it back. There is only one line connecting the freon (r134a) line to the evap. So very slowly and carefully bend the freezer back so it is flush with the back of the fridge. You will encounter the most resistance from the freezer rubbing the side of the fridge itself, this is fine, the fridge sides are what will 'hold' the freezer in place (no need to put new screws in). You REALLY need to be careful to avoid kinking the freon line here. (as a side note, does anyone know what r134a smells like, or any other sign that its leaking? so I and anyone else can know if they do cause a problem and dont fall asleep with this thing running and be brain damaged?)

I should mention, in order to push the freezer back you will need to remove the cover to the temp control (the probe is attached to the freezer) so the freezer can bend in its path. To do this remove the 1 screw behind it, and 1 screw behind the nob (pull the nob off) to remove the case, and remove the 2 screws holding the unit in place. Now bend the freezer down and you wont run into any problems.
Here is a pic of the freezer pushed back.

Now we need to finish it up. I wont be discussing adding a tower or anything on this thread, just how you can get space for 2 cornies and a 5# tank in the fridge. (one bonus over the sanyo is the shelf already exists for the CO2 there is no need to build a plywood one.)

There is no room for cornies with the door plastic on so we need to get it off. Same as the sanyos there are about 16 screws all along the inside of the seal, remove those, pull the door out, and replace all the screws and the seal. As an added bonus, cut out the inside of the door plastic leaving only the outside that touches the liner to hold the seal against the door better.

Screws:


Door plastic removed:


All back together minus the temp control casing:

Now your cornies will fit and you can work on the tower. (Which I will do and upload photos/howto later, but for now this is a picnic tap kegerator)

Enjoy!



Ill try to answer questions in this post as I can. I am in my new house right now with no WiFi and only an iPhone with EDGE. I had to stop at a cybercafe to make the post (addiction? or passionate?)

wouldnt have thought about folding mine down like that. very interesting and great idea. hows the cooling with it in that position? do you have air space behind the freezer section for airflow? keep us updated on the ice over that occurs.

with the fridge at "coldest" in 30 mind the freezer was covered in ice. I felt no cold leak around the door seal and the temp inside the freezer was sub 40f (it was lower than the only thermo on hand could read)

well what i was meaning was the cold plate being bent down do you have air space behind it inside the fridge? I am sure there is since i just did this to mine. but mines a different model. it has an L shape instead of a U shape like yours. I had to bend it gently with force in the center to work it down since it has ledges to hold it up. i was able to get down to 37* as it was with 2 cornies and a carboy and the 17" foam extention. I have cut a peice of foam and mounted the fan i was using to blow air down over the plate to keep air circulating. just finished it up and closed it up with the extension pending time to finish the door. I am going to use shower board on the door.

Thank you very much for this idea.

glad I could help. That was the point of the post.

I would log to see some pictures of yours and how you did it.

Mine has a about 1.5" space behind it and it's touching the walls of the fridge so 0 on the sides.

More cleaencw would be nice but oh well.

that's about what i have behind mine. i figured if it works out ill take some pics of what i did. right now its down to 57*at the coldest setting. i have the fan blowing down. ill regulate it then flip it and see how pulling the air up works. if that doesn't then ill blow forward. i just need to find a way of sealing the air flow so it will pull the air properly. sheet alum is cheap enough so i am sure i can find a way of doing it.
