Here are some common causes of a leaky fridge and what you can do about it. There are four most common causes, they are
The Door that won't close
Any icemaker Hoses
The first thing you need to check is your door seals. Are they dirty? If they are dirty are, give them a clean. Because if there is food or wastes built up on the door seal it won't form an effective seal with a fridge and so condensation can leak. If your seal is really old or damaged then you can just get a new one. Door seals are available for all make and model of the fridge and they are really easy to replace. To remove your door seal for most models you will need to pull it away, or need to use a knife to cut the old seal away.
However fitting a new seal is very easy, you just need to push it into place, there are little ridges, and it's really easy to do. It will take you less than ten minutes. Just make sure you have the right seal for make and model of fridge. You can find the model number inside of the fridge just behind the vegetable crisper.
The door that won't close:
The next thing is a door that just won't stay closed even if the seal is in good condition. This is especially common in fridges that have a large lower door. It is caused by a fridge that is leaning far forward. So what we need to do is tilt it back to make it level. That's done by adjusting the feet. You’ll need to tilt your fridge back, lean it on something or maybe something under there or better yet get a friend to hold it for you, and then adjust the feet.
The next thing you need to do is make sure your fridge is draining and evaporating water correctly. Each time you open or close your fridge door, moisture builds up inside. It condenses on the back wall and should drain away through a plug hole .you need to make sure this is unblocked. Some fridges come with a un-blocker, which you can use just to make sure it's all clear. You will also, on some models, to be able to check the tubing at the back of the fridge. If anything is blocked you will notice water or ice build-up at the bottom, which will eventually spill out onto the floor.
When it comes to freezers, if you have a manual defrost freezer, you just need to defrost it about once every six months or so, or if there is excessive ice build-up in there. Basically, if there is too much ice in there you won't be able to close the door properly and that will mean a leak.
If you've got an auto to defrost freezer an element will come on inside about once every six hours or so and it will just melt away any ice build-up and then this will go down a drain hole. You may be able to get access to that drain hole or not, it will depend on the model of your freezer. If you can get access just make sure it's not blocked with food or ice.
The water ends up down at the bottom of the fridge in the evaporation tray. The tray sits on top of the warm compressor and that warmness makes water evaporate. Check your tray for any signs of damage, any cracks or leaks. Also, check any visible hosing, it could be that your hose, rather than dripping into the tray, is actually dripping onto the floor. Anything is out of place or broken, just replace.
Any Ice Making Hoses:
There usually are three hoses.
One inlet hose which runs from your main water supply into the top of your fridge.
There should also be two drain hoses. One hose which runs from the bottom of the water dispenser to the bottom of the door.
Another drain hose which runs from the bottom of the door into the evaporator tray.
Check all these hoses for signs of damage, and any cracks or leaks. Also, check all the connections are nice and tight and no water is leaking from them.
Once you've done that hopefully, your fridge will be leak-free, even if are unable to fix the issue you can go for the refrigerator repair service center.
