Vendo 39 door question

[kev_7680]

I have a Vendo 39 in my basement.Since the warm weather has hit I noticed that the door you open to take the pop out has a lot of condensation on it (a puddle on bottom) It has the () gasket on, is there something I'm missing on the back of the door? Or is there any suggestions of what i can try?...thanks again for all the help...Kevin
