We're having problems with quite a bit of water leaking from the refrigerator after a month of use. We've removed the lower back panel and found that the evaporator's reservoir was filed up. The fan seems to be engaging, but for some reason, the water is not evaporating fast enough with pretty light use (we only open the door of the fridge maybe 5 times a week). We're in California, so air humidity should not be a problem. We've put the fridge back in place, but without putting back the back plate, hoping that would help water evaporate a bit more. What can we do to prevent this from happening again?
