Hello, Thank you for using this service, I will be helping you with your problem today
Good afternoon, if your handy and have some tools you can do this yourself. the defrost drain is in the freezer behind the back wall. you need to empty the freezer and remove the ice maker if this has one and then the back panel. (inside the freezer) the drain is # XXXXX on this diagram. its in the middle under the evaporator coils, (it will probably be covered in ice) take boiling water and pour it over the ice until all the ice melts and this drains freely. this is a common issue and a poor design. in most cases once you clear it this doesn't happen again. I hope this helps, thanks and best wishes, Bryan
Is this advice for my model? The freezer is a drawer on the bottom and the water collection is above it in the refrigerator. Could the water be backed up all the way to the refrigerator?
