I was looking to create a 3 tap kegerator on the freezer side and a fermentation chamber capable of temps from room temp down to the severing temp of the freezer.
From reading here I saw a lot of trouble bring down the the Fridge side to the serving temp with a fan only in the damper space.
I keep my eyes on craigslist and got a GE side by side for free. It is a digital model.
To work with this model I ordered a defrost timer.
This timer allows for adjustment of both the frequency and duration of the defrost cycle.
I has an 110V coil 10 amp relay on hand.
I also ordered 2 Mini Aquarium Digital Temperature Controller Thermostat
The fans and Dryer vents I got from amazon
I am half way thru this project. I have removed the main baord and have tested the wire harness.
I'll post my progress if you like.
Here are some pictures of what I have got so far.
