I bought this small frig from home depot last year and put a tap on the side for my keg. I was having some problems with it staying cold at first last year and after adjusting the legs to keep the door extra tight it seemed to work fine. Now a year and no warranty later and the thing ain't working right. The little freezer compartment frosted up 3 weeks ago, so I emptied the frig, pressed the defrost button, let it defrost, wiped it up and plugged it back in a few days later. It worked fine for a couple days, but now I can't get the temp below 50 and the freezer compartment is completely frosted over again. It is in my laundry room which has an AC register, so the room temperature isn't the cause. Any thoughts?
