Close the top door, bottom freezer door pops open and stays open

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.

raise the front legs so the machine is tilted back a little,this will help the top door close easier,also most likely you have nothing heavy on the door itself,all a fridge does is move air,the evaporator coil gets cold and the evap. fan blows cold air from the freezer into the fridge side and the air keeps circulating,when you shut the top door it's pushing the air down into the freezer and popping the door open,like i said raise the front legs a little and put stuff on the freezer door so it has some wieght to it and it won't pop open.hope this helps salde

This problem seems to be two sided. A refrigerator defrost it is supposed to take the water from defrost down a pipe located behind the freezer rear wall to a pan below the refrigerator where there is a fan blowing warm air over the water to evaporate back into your home or business. If that drain is blocked your refrigerator will accumulate a large block of ice and frost behind the rear panel of freezer and temperatures will warm considerably in fresh food compartment and freezer. Here is one site I want you to read over=> Leaking Refrigerators Just What may Be Happening and here=> Leaking Refrigerators here is a link to a service manual=> LFX25960xx Service Manual Let me know if this service manual is close enough to your model number. At this point I am looking for air blockage behind the rear panel of freezer. If air is being blocked by ice and frost you can use a hair drier to help speed you up while melting ice. If drain is blocked use whatever you can to open the drain line mentions on the links I sent you to and let me know what is found, Thanks Sea Breeze

a couple of problems can cause door problems first open door and check seal for damage [popped off trac or rip-tears]other is hinges worn- bent-loose --if seal is good at top and bottom of door are hinges check for loose if loose tighten -if bushing lookes like a little round washer type is broken or missing replace --needs realignment loosen top hinge and close door and adjust till door is straight and stays closed tighten door hinge done good luck

the door pops open because freezer and frig. are connected together via duct. air pressure builds when you swing ref door closed. apply a small amount of vasoline to the surface of the hinge side of both gaskets. this will aid in door closure. also the unit may be not level

The light should go off when you close the door. The fanmotor does not operate if the door is open. If it is a frost free unit, it is possible that your defrost system is not working and therefore building up ice in the freezer section and preventing the circulation of cold air to the fridge part.

Okay, I fixed it for now. The design for this bottom freezer drawer is not good. What happened was most likely that my son slammed the door, and it bounced and was slightly open. Overnight, ice started to form all over the compartment, including inside the drawer guides. Some ice was probably obstructing the drawer glide from sliding shut.

What I did, not thinking this was the solution, was to prop chairs against the drawer to close it while I searched for answers on the Internet. In the meantime, some of this ice must have refrozen in the closed position (due to the weight of the chairs). When I went to check it later, I had a little trouble opening the drawer. I gave it a hard yank and some small frost flew off, as I opened the drawer.

It was not easy sliding it due to the frost. I then moved it out and in until it felt smooth, and finally closed the drawer and it stayed in the shut position.

Kids are instructed to close the drawer gently and visually check that it is sealed. There is also an air passage between the refrigerator unit and the freezer so that when you close the double french doors, some air pushed to the freezer section and momentarily pops the drawer open. You should make sure that the drawer closes before leaving the kitchen. If you are on vacation, prop chairs to make sure both the freezer drawer and the french doors stay closed. This is important if you're in an earthquake area as a small tremor could open the doors and you'll get a fire when the lights stay on and burn through the wiring (as others have noted).

If Your Refrigerator's Freezer Door Pops Open When You Close the Fresh Food Door... If a 'top-freezer' refrigerator's freezer door pops open when the larger fresh food door's closed, it's actually a good thing. That tells us the seals are in great shape, sealing well.
Some freezer door 'pop' is unavoidable bc the bottom door's so much larger than the top one and the hydraulic effect of compressing all that air kicks in. The two compartments share the same air via a duct between them, and that compressed air rushes up into the freezer compartment and can 'pop' the door.
To improve the situation, apply a few drops of oil (sewing machine oil or 'three in one' - NOT WD-40) to each freezer door hinge pin. (Even better: if you can, pull the doors and coat the hinge pins with petroleum jelly). This will help the freezer door swing back closed by itself. The freezer door usually stays ajar because it's binding a bit, and that's usually caused by it's swinging 'dry', with no lubrication.
It’s also a good idea to ‘kick’ the habit of letting the refrig door close hard.

Adjust the feet to raise the front of the frige, which should be higher than the back. Therefore the weight of the door will keep it shut or at least cause it to shut itself if it pops open.

Sounds like the refrigerator is sitting lopsided.  Make sure that the front legs are both retracted in the up position.  If it doesn't work, then lower the front leg on the hinge side of the refrigerator.  That will cause the frame to lift the door and it should be able to close properly.
