An apple which is taken out from a refrigerator and kept outside for sometime becomes wet with water

A wet air filter indicates a problem within the cooling system which should be addressed as soon as possible before it gets worse or leads to other system failures. Running your cooling system with a wet air filter reduces energy efficiency.
Causes of a Wet Filter An air conditioner condenses humidity from the air on its evaporator coil. The cold refrigerant circulates through the coil, and as the warm air indoors contacts it, the refrigerant absorbs the heat changing it to a gas, then back to a liquid to facilitate the cooling process. Condensation on the coils drips into a pan to be drained away through a drainpipe. The drain pan can sometimes become clogged, and the filter can eventually absorb water.
Left wet, the filter will not be able to do its job, and reduced airflow, whether from water, results in less cooling and higher energy bills. Another result of a wet filter is the creation of an environment that is ideal for mold growth, which may even spread to other parts of your system and your home. If the system was not properly installed, this could also lead to the filter becoming wet.
Remedies When the air conditioning system is not draining properly, the condensate pan and drainpipe need to be cleaned. If the clog is obvious in either the pan or the drainpipe, go ahead and remove it. Otherwise you will need to contact your HVAC contractor who has tools to clean and clear more difficult or hard to reach clogs.
When the technician evaluates your cooling system, he or she will be able to assess how well it was installed and whether it needs to be modified. The technician can also recommend the intervals between checking the air filter and scheduling professional maintenance. Regular maintanence is one effective way to prevents clogs and system malfunctions.

There is a drain tube that runs from the freezer/ evaporator compartment that allows ice melt water to drain from the defrosting cycle. Often times that drain hole will become clogged with food debris, glass from a broken heating element, paint chips from scaling and mildew, etc. When that drain hole gets clogged the water has no place to go except down into the fresh food compartment. Unplug the ref and remove the food and ice maker and racks. Remove the freezer back panel and look for a drain hole and clean it out. I use a wet/ dry vacuum at first and if the clog is deeper I will use compressed air to blow the line clear. You can also use a water hose with water pressure. Best done outside of the house.

If your house water supply to the refrigerator is poor it is most likely the cause of the water dispenser and ice maker not working. If you hear the water valve humming when the water dispenser is depressed and no water is dispensed it is most likely poor or restricted water flow to the refrigerator.
If you live in an older home the water supply shutoff valve to the refrigerator is usually in the basement or under the kitchen sink. Many shutoff valves are called a saddle valve and the valve is secured onto a cold water pipe and as the valve is turned clockwise a pin punctures the water pipe allowing water to flow. Saddle valves often become clogged with minerals and can completely block water flow to the refrigerator,. If the valve is corroded on the outside it should be replaced. Ice maker installation kits are available at most hardware stores. Copper water line kits are preferred. Cost is under $25.00. If the Saddle valve is in good shape they can be taken apart and cleaned. Be sure to shut off the main house water and drain pipes before attempting to clean.
Newer homes may have a water box in the wall behind the refrigerator. Sometimes these can become clogged with mineral deposits as well.

Hope this helps.

A 99% bet is that the heater coil is leaking. It is located in the dash on the firewall-passenger side.

Have you had a chance to locate the location the water inside freezer? There are many reasons for this to happen I just can not say it would be a defrost condensate drain blockage. Most times it is. Every 8 to 10 hours your freezer defrost and the water is surposed to follow a pipe or drain through the refrigerator to a pan below refrigerator where the warm air from condenser evaporates the water back to the air inside your home. That drain line sometimes slowly becomes blocked and then the drain hole becomes clogged with ice. Once that happens the drain needs to be cleared. I will try to help you solve this so for now I need you to see if water looks as if it came from rear of freezer. Placing photos on Flickr would be great! So tell me where you see it and yes we may need to pull a few things out. This is nothing a few towels, hair dryer hot water and Clorox and a wet vacuum cannot handle. Sea Breeze

if theres condensation on the walls too, check the door seal,it could be letting in warm air from outside,also if there are slide vents on these drawers open them so you get air flow

check the floor and the trunk for water,it sounds like something is damp,or got wet. start there, also make sure heaterbox drain is clear, drain sometimes plugs up and the condenstion water then fills in the box and leaks into pass/side floor instead of draining outside. hope this helps.

Self-defrosting refrigerators usually dispose of the water generated during the defrost cycle via a tube or channel that directs the water to a pan at the bottom of the refrigerator. From the pan, the water normally evaporates. (See a more detailed explanation of this in the How Things Work section of our website).

If the tube or channel is clogged or obstructed, the water backs up and leaks into the inside of the refrigerator compartment. Then the water builds up at the bottom, inside of the refrigerator. When the water has built up for a time it may spill out of the front of the door opening. To fix this problem, clear the drain tube or channel and allow the defrost water to flow down to the drain pan.

In some refrigerators, the defrost water is intentionally directed down the back wall of the refrigerator, where it then flows to the bottom of the refrigerator compartment and out to a small drain--usually located beneath one of the drawers at the bottom of the refrigerator. If the drain becomes clogged or blocked, the water may back up. To fix this problem, clear the obstruction.

Another cause may be the following. The refrigerator may have doorframe heaters to evaporate any condensation on the cabinet frame. If your refrigerator is equipped with a switch inside that says “energy saver” or something similar, while running in that mode the door heaters are disabled. Turn the switch to the opposite setting and wait 24 hours. If the condensation disappears the problem is solved.

In a unrestricted rigid metal vent no water will accumulate. A dryer is exhausting hot and humid air to the outdoors. If the vent becomes restricted with a lint buildup, that lint can become wet. The more restricted the airflow is, the less airflow is available to remove the moisture. if there are low spots, or a flexible vent is used, pockets of moisture can accumulate......especially on a longer vent run.

hi there your fridge has whats called a wet wall evaporator where it freezes up then turns to water and runs down the wall , if you are getting water sitting in the base of the fridge check the drain hole which is sittuated at the bottom of the wet wall evaporator for any blockages ie. bits of food or paper labels.

hope this is of some help
