I'm in the middle of a project where I'm taking an old, working mini-fridge and am converting it into a kegerator. However, I've hit a bit of a snag. When I was drilling a hole in the top of the fridge to place my draft tower, I nicked two copper lines that appear to be connected to the compressor of the mini-fridge. I'm guessing it's from the compressor because as soon as I hit the lines, air came shooting out of the holes in the lines.
I shut off the fridge and patched up the holes using some plumber's epoxy. I thought this solved it - I couldn't hear air coming out of the lines anymore. However, although I can hear the fridge running with no air leakage, it's not getting cold at all.
Did I ruin a perfectly good mini-fridge, or is there a way to fix this? I'm wondering if when I patched up the holes in the lines if I used too much epoxy and am blocking the airflow necessary to cool down the unit. I don't really know much about how a fridge or a compressor or a cooling unit in a fridge work, so any advice would be much appreciated. Thanks!
