I recently got a refridge (top/bottom model--whirlpool) and installed a Johnson control. Main use is for fermentation of ales and lagers. Really like how the Johnson control works at keeping temps where they need to be!
At the moment, the top freezer isn't really used (too small obviously) other than storage. Can always use storage, no problemo. However, I want to beef up the efficiency of this fridge. The two things I want to do are to allow the cool(er) air in the freezer to circulate into the bottom fridge. I imagine doing this would reduce the time the fridge cycles. The second is to add some more insulation. Maybe that is overkill, but I have the room to do this (never more than 3 carboys in the fridge at a time) but if I remove the door shelves, I was thinking of adding a 1" layer of foam there (since I already have this.)
So to my questions: What would I use to cut a hold in the floor of the freezer to the fridge? (I believe the coils are on the back, but will make sure before attempting this, of course.) How big of a hole is needed and should I include a fan to move the colder air in the top to the bottom? If I do need a fan, how do I get electricity to run it?
When doing a search all I came up with are those who completely took out their freezer floor, but I don't want to mess with that (yet? )
Thanks for any help!
