First pipes now fridge...

[overlander76]

The refer door was sticking on the bottom and I noticed there was water all over the bottom of the fridge and leaking out the door on the floor. It was icing up on the bottom of the door and for some reason it's defrosting and the ice is melting into the tray thing, draining down the hose into the little tiny thing that directs the water outside. However the little tiny thing that funnels it out is frozen and it's overflowing. My question is, could this have something to do with the cold? It's zero outside. Why is it defrosting? Maybe it does this all the time and I'm just noticing it because it's overflowing? I was just outside and noticed that under the refer, visible through the access door outside behind the refer, the skin is open and there is some type of screen material covering the opening. Is this normal? You can see the ground. Is there anything I should keep in mind for operating the fride in cold weather? It's running on electric. The small square pan outside, on the rear of the fridge that collect the water from inside the fridge is dry. It's the stock fridge from 76.

Thanks again-
