Do what I did to my friend when she said hers was blocked. I got the fridge out so the outside end of the drain tube was visible and I could get my mouth on the end, Wrapped kitchen roll round it so as not to mess my lips and said to my friend that she should look closely at the hole in the inside of the fridge AND GET AS CLOSE AS POSSIBLE to it so she could tell me exactly what was going on.
So with her head up to the hole I blew as hard as I could. You can guess what happened... She swore a bit, but she has a good sense of humour and laughed, but she couldn't complain as her fridge drain was clear.

It's a tube - you don't need to undo anything...
