Refrig noise

Have an Amana refrig. Model# DRS2662AW and Serial# PDRS2662AWD

Makes a gurgling noise sometimes when you close the freezer door only. Almost like water is trapped in a drain line and closing the door forces air out thru the line.

Then I also that sometimes the refirg door is hard to open. Over a couple of weeks the whole refirg ends up a few inches from the wall. So every couple of weeks just push it back. But had it for years and never had this problem. Gasket is clean and don’t think its sticking.
Acts like there is some sort of air lock or suction in the refrig section that makes it hard to open sometimes.

Does any of this make sense?
Is there maybe some type of air valve in a refrig that could be bad?


Thanks for any help.

Also did find this P trap thing in the bottom. Tried to remove the hoses to was out but they seem glued in.
