What causes the refrigerator door water dispenser to leak after dispensing water?

Answer 1

The seal around the door is bad. When the refrigerator doesn't have a complete seal around the door it allows ambient air to get in. When the compressor runs to the temp average inside, it actually is vacuuming slightly inside the unit and exhaling. Means it is pulling outside air in through the door seal.

Moisture in the air condenses inside the refrigerator and puddles on the bottom.

Answer 2

This is usually a defective shut-off valve. You will probably have to replace it. It may also be ice crystals in the line. Run the water for a long time until it is no longer cold. If the valve does not leak, replacing the valve will not solve the problem. You might find a temperature setting that is a good compromise.

Answer 3

Water can form in a fridge in the form of condensation.
There is a catch basin in the bottom of most refrigerators to catch this condensation and it may be overflowing.
Check that the door is closing all the way and the gasket that seals around the door isn't messed up some how.
If the 'fridge has an automatic ice maker, turn the water off to it and see if the leak stops.

Answer 4

The 'leaking' is a result of the heating element that defrost the coils of the freezer. The resulting water drains down the the back or side walls to a collection point, usually under the 'crisper', that drains into a pan under the compressor, whose heat evaporates this moisture.

Answer 5

The primary cause for a refrigerator to leak is a failure of one of the seals or gaskets. This allows cold air to escape and cause the fridge to work much harder to stay cold.
