The object was to make a temp controlled fermenter and kegerator as inexpensively as possible, and this is what I ended up with. It will hold four carboys and four pin lock kegs with a little room to spare. Eventually, I'll put a plate and taps over the hole on the freezer side, but for now it is working perfectly (if really ugly).

I got a mid 90's fridge / freezer from Craigslist. It was rusted out under the ice dispenser so that area got cut out and the area filled with expanding foam. To make room for the kegs, I took the inside panel off the freezer door, cut out the edge and reinstalled just the edge with the seal. The shelf is held up with 1/2" allthread that is run through the entire width of the unit. Freezer temperature is controlled by a eBay aquarium temp controller connected where the original thermostat was. The fridge temp is controlled by a 2nd eBay controller connected to a 12v PC fan.

I was lucky in that none of the circuitry in the ice dispenser was necessary for the unit to cool and that a wiring diagram was inside the freezer.

The homer bucket and 5 gal water jug are for demonstration purposes only...

This was the last thing I needed to get back into brewing, and I can't tell you how excited I am!

Thank you for posting a picture of the inside w/ the carboys and kegs. I've seen a couple builds so far, but hadn't seen one that would fit 4 kegs (which is my goal). Depends on the fridge of course, but at least it looks like it's possible.

I picked up a side by side Whirlpool last night. Probably will get started on it today.

My advice is to plug it an and make sure it runs for a couple of days before you tear into it. I didn't do this and and I was a bit anxious when I first plugged it in. If it didn't work I wouldn't have been sure if it was something that I had done.

Good idea.


I made sure it was cool inside before I picked it up though, but I'll plug it in today and let it run while I parts together.

Turns out my fridge was set up like yours, so I'm thinking I'll need to add a fan to pull cold air from the freezer to the fridge. On another thread I read that this setup didn't control too well.

How is yours working? Can you control fairly accurately (for the fridge side at least)?

I have the freezer at 40 degrees and the fridge at 70 and it holds temp fine. I tested the freezer to around 20 degrees and the fridge still held temp. The fan is just screwed into the wall where the foam damper was.

That is a really sick unit you have there. I would love to have something like that where you can ferment and dispense. Hell, you could even lager in a corney.

Cool. Thanks man.

I have a 120V PC fan, but sounds like I need to use a little 12V like you have. I got one laying around somewhere.

Do you have any plans to add heat to the ferm chamber side for the cooler months?
