Sounds like you have a defrost problem, check defrost timer, defrost thermostat or defrost heater

How does Auto defrost work and how long does it take


Hello there
A Look at the Defrosting System:
Modern refrigeration systems, whether industrial or household, feature a defrost system. A refrigeration system works by developing temperature below the water's freezing point. Long hours of continuous operation may lead to development of a layer of frost or ice around the freezer or the evaporator coil. This hinders the cooling capacity of the evaporator, making it difficult for the cooling effect to pass into the freezer. Without refrigerator defrosting, the layer of frost or ice leads to loss of cooling and lessening of performance coefficient of the refrigerator and higher electricity costs. There are various defrosting methods that your fridge can employ. Take a look at some of these defrosting methods.
Thermostat Defrosting:
Thermostat is a basic component in all modern refrigerators. The device allows you to set the freezer temperature that you want, depending on your requirement. Most often, a refrigerator with thermostat comes with a small plastic tray which can be found below the freezer compartment. This tray is where the excess water from your freezer goes to. The thermostat works by stopping the supply of power that is received by your compressor whenever the temperature that you have set has been reached.
The refrigeration unit stops producing the cooling effect whenever the thermostat stops, which happen several times a day. And during this stage, the frost or ice collected on the freezer starts to melt, with the resulting water collected in the tray. A small tube connects the tray to a small outlet usually located at the bottom back side of your refrigerator. A pan is installed there where the tube brings the water resulting from melted ice after defrosting.

Your freezer drain is clogged or frozen up with ice blockage. Need to remove the freezer floor liner, usually 2-4 1/4" screws holding it in - slide it out. Next slowly pour hot water over ice build up and melt all ice. The drain is under the evaporator coils (small hole near center) this connects to a pan under the refrigerator that then evaporates on its own. I usually place a couple of bowls inside fresh food area on top shelf to catch excess water dripping through ceiling of fresh foods.

Next you will need to attach a heat probe from the heater under the freezer coils and feed it into the drain in order to prevent freezing up again. Use part #819043 heat probe or strip some #14 gauge copper wire and wrap around heater once and place down through drain. Recommend the heat probe 819043 to get it right the first time.

My whirlpool refrigerator is 4 year old. the ice maker is not installed I am getting water in my refrigerator now for over 5 months. There is no sign of water dripping down from the freezer or the back...


The evaporator coils frost up in normal use and every eight hours or so the entire unit shuts down and the defrost heater comes on to melt the frost. This cycle last about 20 minutes. The melted frost drips into a drain pan and through a drain tube to the drain tray under the freezer/refrigerator where it's evaporated by the condenser fan.


Your drain tube may be stopped up with ice at the upper end because it drains too slow because it's stopped up at the lower end in the evaporator pan under the unit at the floor. It can get dust and mold in it. Once you get the ice out at the top a little pressure with a turkey baster will usually clear it out. Flushing it out with hot water and clorox may help.
Make sure it drains quick enough to prevent refreezing. . The drain should be located below the evaporator coils on the inside of the freezer at the bottom of the rear cover.

Take a bare copper wire and wrap it around a fin near the heater and put the other end a few inches down the drain. The heat convection may prevent it from freezing.

I've got a small leak in my refrigerator. I thought it may have been overspray from the ice maker but we still get water in the refrigerator when the ice maker is off.

About every 2 months the defrost drain gets plugged

Top & middle shelves COVERED with frost/ice, not middle


That is normal. The refrigerant runs through those shelves. They are the evaporator side of the unit.That is where the freezing effect comes from.
Check door seals for leaking air.
Keep door openings to a minimum.
Get in there and get out.
Those things will help prolong frost/ice buildup.

Ice build up in bottom of freezer


Check the ice maker. sometimes they get cracked a will leak water into the freezer compartment. Also check the ice maker fill tube for leaks or someone could have spilled something. Although this is tipical of a clogged drain. What happens is when the fridge go into derfost, it will melt all the frost that is on the evaporator, turning it into water. The water drains down to a trough under the evaporator and down a drain hole in the trough ( this trough is behind the evaporator cover ) Removing the melted frost from the freezer. If that drain is clogged, the water cannot leave the freezer. Then when the fridge starts back up ,it will freez the water that was not drained. After repeated defrosting the water will fill this trough and run off into the bottom of the freezer to be frozzen when the fridge starts to cool again.
