Doing a Side by Side build for a friend. The fridge is a Maytag. I made my own last year but didnt take any build pics, so I decided to follow this one. Today I installed the top and bottom fans to be used as a push pull system for cold air from the freezer portion. Normally I only use the top fan if lagering (heater if fermenting at warmer temps) but will use both to cold crash or just change temps faster.

More of the bottom fan. They are 120v AC fans. I and using laundry duct louvers to help keep the 2 sides separate. The last pic is just a screw driver holding the louvers open.

Here is the top fan being installed. It will be below the control housing on the fridge side. I mounted the fan in the wall here because I didnt want to take up room in the freezer side, plus I still have to add a piece of ductwork to pull the cold air from behind the rear wall (just like the original system did). The bottom fan just sticks into the refridge side and will be below the shelf, so I didnt care how far out it stuck.

Finishing up the top fan. I had to build a spacer out of wood for the fan since it didnt sit entirely inside the wall.

Very clean and professional work!

Here is the fan shroud I made out of some sheet metal. I had to cut a new hole in the false back wall to allow airflow to it. I put the old shroud back on after plugging it up with insulation. I figured I already lost that space to the new one so I putting it on wouldn't matter.

Starting on the freezer side door. This refridge is better than my last since it has screws holding on the plastic. I had to cut the other one with a razor knife. I pulled the wire out of the door so I could cut the counduit shorter since I only needed the wires up top at the controller, then fished them back in. Next I cut a piece of 3/4 plywood to cover up the hole left by the water/ice dispenser.

The freezer door continued. My buddy won't be putting taps thru the door right away, but I set it up for when he does by adding the 2x4 to the back of the door. The last pic is the board I will attach to the front of the door to cover up the water/ice dispenser hole and to drill thru for the tap(s).

Here starts the Refridgerator side door. I decided to keep and use the egg storage compartment this time. I cut it off of the rest of the door to make it easy to put on and take off since all of the wiring will be behind it. The doors will have to be off when placing the finished product in his basement, so instead of taking the entire door apart I only have to take the top part off to disconnect the wiring.

I put 3 switches inside the egg holder door to turn on and off the fans and heater. The wood on the back is just to add support since the plastic is pretty thin. On the bottom I cut a hole for a romex connector used for the wires coming from inside the refridge. The last picture is a shot of the wooden spacers I hade to make. The Love controllers are too deep without them.
