Default Top-freezer Roper fridge fermentation chamber

Hey all,

I just came into possession of a Roper top-freezer style fridge. Model RT18BKXKQ01 if you want to play along at home.

I've read a LOT about cutting into the walls of fridges, and watching out for coolant lines, etc etc etc. But I also saw this awesome Side by side fermentation chamber build and thought it'd be nifty if I cut the floor out of the freezer, and build some shelves into this one.

Call me crazy, but I don't think there's anything in the freezer floor of this fridge. Or the walls. In fact, it looks like the evaporator is in the freezer, on the back wall, with a fan to circulate the air.

What do y'all think? Is it worth cutting out the floor to see what's in there, and maybe gain some more space inside?

Here's the parts diagram of the mechanics of this fridge. This makes me even more confident there are no coolant lines in the floor. I expect a bunch of wiring, though...



Cheers!!!!

Here's a photo of the fridge. I took out the liner in the door, and it can fit a Sankey in front of the hump! I'd love to build a shelf and fit a couple carboys above that....

Well, there were no "OMG You idiot!!!!" posts, so I guess this isn't all that bad of an idea... I think I'm going to start hacking away at it tonight. Ill take pictures and post updates here...

My plan is to connect the doors together (to form one door), and carve the freezer floor out alltogether. I should end up with one, large compartment.

Then, I'll build some wooden shelves, so I can put a couple of carboys on each level. My goal is to keep at least one Sankey and one carboy in there. Preferably two or three carboys.

Anyone have any thoughts or input?

Will do! Hopefully it won't be an epic failure. Regular failure is always an option, though.

Yup, the evap is right behind a single plastic panel. I'l take some more photos and post a little later today.

This system is actually very, very simple it looks like.

OK, so I carved out a hole between the fridge and freezer. HEre are some photos of the affair tonight. How's this for photos.....


The fridge with the evaporator exposed, and the door shelves removed.


Close up of the evaporator


Plastic removed. Let the foam carving begin.



I know there are wires in there somewhere, so I carve carefully.



Wires located.


I sanded down the foam with a wire brush drill bit. This crap goes everywhere.......



Opening complete.


Next up, I'm going to build a wooden shelf in there, so I can fit a couple of carboys below, or a sankey, and something above.

Hm, this thing works pretty well. It just took it two minutes to drop the temp in the fridge-chamber from 55 to 49. And the eBay aquarium controller works pretty well, too!

Tomorrow -- shelf building.
