Fridge door pops back open

HOW DO YOU SHOUT OFF A FRIDGE ? THEY DO NOT HAVE EARS TO LISTEN WITH

I have a refrigerator with a top freezer that was constantly popping open, just enough to let the heat in and melt anything inside. This can also cause heavy frost build up from condensing humidity in the air. The frost can build up on the front face of the fridge where it meets the magnetic gasket on the door making it even harder to keep the freezer closed.
The cause in my case was that slamming the refrigerator door sent a puff of air through the ductwork to the freezer above. The sudden pressure increase popped the freezer door open and the door wasn't heavy enough to close on its own. Since this is a beer fridge in my garage I fixed it by putting a stick on childproof latch from H-D on the freezer door. :-)
If this was our main fridge indoors, I would first check to see how much force it takes to open the freezer vs. the refrigerator section. It should be about the same. If not, check the freezer door gasket to be sure no food or ice is built up on it and that the mating surface is clean. Check that the door is closing parallel to the mating surface. A misalignment would make it hard for the gasket to seal or stay sealed. Adjust hinges if necessary. If all seems ok, check to see if the fridge is level or possibly needs to be adjusted so it tilts back just a bit to make the doors self closing and not fighting gravity to stay closed. If all else fails, inspect the door gasket to be sure it isn't broken or stiffened with age. Inspect the bottom of the door gasket with a mirror. I once had a side by side with what looked like a good gasket until I felt around the bottom of the door. Replace if necessary.

it may be necessary to reset the hinge adjustment to move the door further across the opening giving the magnets a better area to hold on to . there is a slight amount of adjustment in the mounting points of the hinges. You may have to replace the door gaskets as they become hard over time and the magnets cannot work properly in the hard plastic

That is a common problem with over-under units. You can clean or replace the door seal or, tilt the unit back a TINY bit. The door pops open because there is a common airway from the freezer to the fridge. When the fridge door shuts too fast, it pushes a lot of air into the unit. It needs to go somewhere so, it pops the freezer door open. If you shut the freezer hard enough, you will be able to pop the fridge door open.

from the description given I came up with;
possibly the screws are lose on the top door hinge, the top or bottom hinge is worn, the door is warped or damaged.

After all the good ideas you've already tried, the next things on your list could be:
(a) level the floor under the fridge - they often sag under the heavy weight of a loaded fridge due to moisture/rot.
(b) level the fridge itself - using the leveling legs. If the fridge continues to have a problem with
the door poping open, try raising up the front of the fridge above level.
(c) unload the door pockets - making the doors lighter may help solve the problem.

Hello, In a word, Yes. It is totally normal, when you close a door it pushes air into the unit and depending on how it is closed the other door will "pop" open slightly from the "push" of air. Thanks for coming to fixya. macmarkus :)

check that the door is closing up tight, if its even just a little bit open it sucks in hot warm air and when this cools it has a lot of water in it, this is were the water is coming from, also if the door is open a lot of times a day that will cause it too, some people leave there fridge door open every time they get things out of there fridge and dont close it untill they put the stuff back in? and all the cold air has fallen out the bottom by then,,so the poor fridge is working its head off and getting no were fast,

well u need to check the rubber of ur freezer ;s door .some damaging in the rubber is causing the problem.

If door does not close at all, even if you push you need to replace the door pickoff.
If door stick a bit but does not stay closed you have to replace the door seal.

Here you find all diagrams for your appliance
