I have a Sanyo mini-fridge as the cooling source for my ferm chamber. Any thoughts on how to keep the freezer portion from running? I do not see a control switch for just the freezer.
Most fridges work using a "trickle down " effect whereby there is only 1 cooling coil, and it directly feeds the freezer. The cool air falls down into the fridge area, cooling it.
If you remove any shrouding/door from around the freezer area, then the fridge part will cool quicker, and the compressor won't run as much.
I did this w/ an old fridge I use for beer storage which was freezing up. W/o the freezer area shrouded, it doesn't freeze up there anymore, although I do use a temp controller to keep the fridge area at a set temp.
I have included pictures of my particular fridge. I thought about crimping the line but that could be tricky and actually cut the line open (not good). What if I installed a small fan (like a pc fan) near the freezer portion to keep the air moving around. Would this prevent the ice build up on the freezer shelf? Could I wire the fan to my temp controller so that it would only turn on when the fridge turned on?
