I will give you the short and long answer

Short Answer: Normal

Long Answer: Heat is attracted to cold, When you open your freezer, warm air rushes in, you get what item you want then close the door... the warm air is then dragged across the evaporator coil thus creating a momentary vacuum as it contracts. Now as it creats this vacuum, it can get the balance of air from either the drain tube (giving you a whooshing or whistling noise) or even through the flashing (corner) of the gasket where there is no magnet and is the weakest spot of the gasket.

hope that helps.

Yeah, he's got it right.  You should try it with a -120 degree freezer. The door sucks closed so hard that it's impossible to open the door for a few minutes.

-120*F?????

I thought it was bad when our Sub Zero's would have a compressor relay on the board stuck shut and it gets to -22*F

-120*F ... Wow!!!!
