I have struggled with this issue for months, and I have defrosted for 2 days (with my freezer this consists of taking everything out of the freezer), and as someone stated, this is just a temporary fix. Its very annoying and time consuming only to have it continue. Since I always use the internet to fix appliances, I thought I should add my fix. My evaporator motor was also getting noisy, the fan was hitting the motor - design flaw. Once I replaced the evaporator motor I no longer have any water/ice in the bottom of my freezer. It makes sense, a bad evaporator motor not doing it's job allows the defrost water to accumulate. I am not a pro, but since I replaced the motor and the fan blade, I have NO WATER at the bottom of my freezer, and now my freezer is a lot quieter! I hope this helps someone, because I get a lot of help from other people out there! Update (02/11/2017): Oh, and the evaporator motor was very easy to install, and costs about $90!
