I have checked the seal. I don't believe there to be any drainage system and hence this cannot be blocked.

Should I try to turn the temperature up so it get warmer, or down so that it get colder?

Is there any other possible effect?
Answers:    when it goes into defrost it drains look at top inside of fridge sometimes you can procure to drain hole there other times thru the bottom of frezzer remove the floor of frezzer could own trash or ice within drain hole
Have a look on the ledge only above where the salad boxes are located,you should see a hole usually have a little plastic stick near a ring on top.Plunge that up & down a few times,give your fridge a expeditious clean inside. I save my fridge on number 3 as this is usually sufficient.Clean up all sea & check back after awhile to see that its no longer leak.If it does,then most feasible your thermostat may have brimming with up.
