First of , this is a great forum. We bought a new to use 5er this spring and the information on here has been invaluable to us newbies. I like to know how things work before I use them and reading through this forum has provided a huge amount of knowledge.
So, today I turned on the fridge just to make sure it works and after about 4 hours I was sitting in the trailer reading the manual when this intermittent whistling kind of sound that increased in pitch started coming from the fridge. First thought was gas but then I remembered that it was turned off. After a few times I realized it was coming from the freezer area. I assume that as the air inside cooled down that a vacum was created and air was being sucked into the freezer, the door was really hard to open. The seals seem to be ok though.
I'm assuming\hoping that this is normal?
