It is a normal problem with all refr. there is a drain tube at the rear of the unit the has a "drain loop" it gets plugged after a few years. try and remove the tube from the clamp, and run water thru it to clear the blockage. you will also need to remove the ice from under the freezer coil after you clear the tube. after that the regular defrost cycle will take over and work properly.

SOURCE: GE built in Fridge does not defrost and freezer ices up

Defrosters are commonly controlled by a primitive timer and this may have a 'dry' and a 'wet' (humid) climate setting that will cause the defroster to cycle generally every 12 or 24 hours.
If set wrong (by accident or on purpose), it can allow too much frost to accumulate before attempting to defrost.
This can cause a gradual buildup of ice.

Also the heating element for the freezer may have failed open so it never heats at all. The connections that need to be checked are often buried between the in- and outside walls.

The timer is probably still OK since you apparently aren't having a problem on the refrigerator side.

SOURCE: GE TFX20JR side by side/water leaks out freezer during defrost

Yes, you are correct, that is a drain. Use a turkey baster with hot (not boiling) water to flush out the drain tube until water will flow out into the drain pan under the refrig. (where the air blown over it will cause it to evaporate)

Remove the freezer bins and shelves.
Remove the rear freezer panel.
The drain is on the bottom center of the freezer after the rear panel is removed.

It doesn't defrost
  1. Defrost control board
If the defrost function is not working on your refrigerator it could be an issue with the defrost control board. This control board oversees several internal conditions and regulates the activation of the defrost cycle. A faulty board can be the primary reason your refrigeration unit is not transitioning to the defrost cycle. Over time, the buildup of ice on the evaporator coil will prevent the refrigerator and freezer from maintaining proper internal temperature. It is advisable to first check the defrost heater and the defrost thermostat for continuity prior to replacing the defrost control board.
  1. Main control board
A possible cause for a refrigerator not defrosting, especially on more modern units, is the main control board. The main control board acts as a "brain" for the unit controlling the defrost cycle, compressor, and run time, and essentially acts in place of the defrost timer. The control board can be tested using an ohm meter for functionality and will need to be replaced if bad.
  1. Defrost timer
If the refrigerator is not defrosting the timer could be malfunctioning. Numerous times throughout the day the defrost timer should cycle the defrost heater on as a means to melt frost buildup on the evaporator coils in the freezer. If this timer does not cycle on, then it may be faulty and require replacement.
  1. Defrost heater assembly
If your refrigerator is not defrosting accurately this could be an indication that your defrost heater assembly has failed. This could cause the frost to accrue on the evaporator coils, eventually blocking the airflow resulting in the unit not cooling properly. The defrost heater assembly can be monitored for continuity using an ohm meter and will need to replaced if there is none present.
  1. Defrost thermostat
Another cause of your refrigerator not defrosting is a faulty defrost thermostat. A requirement for the defrost heater to activate to melt away frost on the evaporator coils is a functional defrost thermostat. The defrost thermostat senses the temperature of the evaporator coils and initiates the thawing process by activating the defrost heater. If the thermostat is faulty, it will not sense the lowering temperature of the coils and will not turn on the heater, resulting in an advanced frost build-up. The defrost thermostat can be checked for continuity by using an ohm meter; if there is no continuity the damaged part will need to be replaced.
  1. Defrost sensor with fuse
Another possible cause of a refrigerator that does not defrost properly is a defrost sensor with a fuse. If the defrost sensor fails, the fuse acts as a one-time-only fail safe for the sensor -- if the sensor does not shut off the defrost heater, the fuse will blow when the set temperature is reached. This safety precaution is to keep excessive harm from your unit by the heater and is a one-time use, resulting in the replacement of the entire defrost sensor.
Defrost drain problems
  1. Clogged or freezing defrost drain
If you are experiencing defrost drain issues, it is possibly due to a clogged or freezing drain that is blocking water flow to the bottom of the freezer. This will cause the defrost water to drain and drip down to the bottom of the freezer section. To correct this issue, thaw any ice or remove debris that could be causing the clogged drain or replace the drain heater.
  1. Drain heater
If you are experiencing defrost drain problems, inspect the defrost drain heater. A dislocated or burnt out drain heater will result in the drain tube freezing over. Attempt to return the part to the designated position or replace the damaged part to correct the issue. Search Over 2 1 Million Appliance Parts

Why is water leaking out evey day???


Is the water leaking from the refrigerator compartment or the freezer compartment? Can we assume the "leaking" water is more than some accumulated humidity/moisture (check your door gaskets)? Have you checked all water lines/fittings for the water dispenser/ ice cube maker (if you have one)?

If it is is the freezer section, the problem may be a clogged drain line (is there ice blocking the trough drain hole?) at the bottom of the freezer (evaporator) coils? You may need to defrost the freezer, check for any faulty parts (e.g., defrost time/ADC, defrost thermo, defrost heater), and clean the drain trough/tube. See Refrigerator Defrost Parts for illustrations.

That water is from the melting frost of the automatic defrost cycle. Their is drain in the freezer behind the back wall under the evaperator coil that is blocked, so instead of defrost water draining it's pooling in the freezer or in some case espically on models with the freezer on the top,the water is leaking from the freezer vents into the fresh food compartment.
The way to clear the drain is remove back plate and remove all ice build up and GENTLY make a small hole in drain through then totally flush w/warm water.
The exact location of drain is under the coil behind back freezer plate in the centeroldtech2332_52.jpg

You either have a problem with the defrost circuit or the drain tube is blocked. To check you will need to remove the back panel from the freezer section to check. Behind that panel is the evaporator or cooling coils. If it is completely encased in ice, then the problem is that the defrost circuit has failed. To troubleshoot, see below. Otherwise check the drain tube for blockage. It is located just below the coils in the center Remove any debris and stick a length of wire down the drain to clear it of any blockage. Pour a cup of water down the drain and check that it goes down and enters the pan below the fridge.

The water source that is causing ice build up on your coils comes from the air. The coils are below freezing and the water in the air are freezing on to the coil. The defrost circuit in your fridge has failed. It is made up of three parts, the defrost timer, defrost heater, and thermostat.

The way it works is that normally the compressor has power for 8 hours, then the timer cuts power off and sends power to the defrost heater for about 45 minutes. The heater is attached to the coil and warms up the coil to melt the ice. When the coil reaches about 40 deg F, the thermostat which is in series with the heater, opens up cutting off power to the heater. This prevents the freezer from getting too hot. After the 45 minutes are up, the timer switches the power back to the compressor again to restart the 8 hour cooling cycle.

Any of the three components can fail causing you not to get the defrost cycle to work. Typically the timer stops advancing so you either stay in permanent cooling or defrost mode. Or the heater burns out so it can

The drain at the center-base of the freezer freezes shut with ice. Water accumulates on the frig shelves and under the veg bins. Why and what to do? Frig is a Whirlpool 21 cu-ft ET1CHMXKB03 built in 2004.


There is supposed to be a defrost element that goes through the first part of the drain, it may have been pulled out or it may be malfunctioning. After the evaporator defrost cycle the water should drain through the drain tube, since it's frozen up the water just accumulates in the fridge. If you take off the inside panel that covers the evaporator coils (the coils that freeze up) you should be able to see the evaporator defrost element and the drain defrost element. Inspect the drain defrost element to see if it's in the drain tube like it should be or if it needs to be replaced.

Coils freezing over inside a side by side


Most times when coils freeze up it is due to the failure of the automatic defrost circuit, specifically either the defrost thermostat or the defrost timer. Occasionally it is the drain under the coils somehow gets clogged and the water from the defrost cycle doesn't drain. If you have water in the fridge side or water forming ice outside the back panel in the freezer the defrost is probly working and the drain is clogged. YOU MUST GET ALL THE ICE OUT OF THE DRAIN. Hair dryer, hot water, etc must be applied. Water MUST flow freely to the drain pan below.
