I was wondering if anyone uses one of these chillers. I've had the 1/10 hp model hooked up for two days now. It goes dark for hours at a time. It seems to be keeping the tank cool but I'm not sure if its just the cool weather we are having. I emailed the retailer but have not got a response. I woke up this morning and the display is on, was on for several hours. The compressor kicked on once during the morning. Got home from work and its dark again. Even if you press the buttons, nothing happens. Does anyone have any idea if this thing is acting normal? Thanks for any help.
