You are seriously frozen up. Defrost the unit completely. Then, be aware that 'window shopping', leaving uncovered liquids in the box and poor door sealing (too heavy a load on the door ... too much on shelves) can cause condensation. Defrost with hot air or leave unplugged and open for about 2 days. You'll see alot of water come out.

SOURCE: Hidden Ice build-up inside plastic bottom cover of freezer

Generally, icing is the result of too much water vapor inside the unit, blockage of the circulation channels and too much packing in of the box.  The water vapor is generally caused by: uncapped items in the fridge, opening the door too often, humid conditions, bad door seals.  There is of course, there is a possibility that the defrost cycle on the unit is not working.  About once a day, depending on the brand, you should notice that the fans and compressor don't run and you should hear a bit of creaking, sloshing or other strange noises as the ice melts.  If this is not happening, your defrost timer or the coil it heats could be bad.

SOURCE: ice build up under rolling tray in freezer

Yes you are right there is a drain tube in the middle of the coils. You need to remove the back panel and you will see the coils of the evaporator (freezer) and right underneath you will see drain tube. Now more then likely it is plugged with ice so take some regular table salt and two or three teaspoons on the top of the tube opening will break it loose and start draining. Take some regular tap water and pour down just to flush the tube and inspect the bottom collection pan under the fridge and see how much water is coming out. Be sure to have unit turned off when you do this cause the fan will run inside the freezer compartment other wise. Hope this helps you. ken

SOURCE: frost build up behind/inside back freezer panel

I have same problem, it usually happens after someone leaves door open too long or after 4-6 months. I usually place two frozen milk jugs full of water in the upper fridge and tape the upper fridge door closed at night before bed so the kids don't open and let the upper food get warm., Unplug the fridge and open the freezer and remove all drawers (place excess frozen food in freezer in garage) , leaving the freezer open with a towel in the bottom to catch the melting water from the back panels inside and the next morning wipe the fridge bottom clean and plug it back up and replace everything. I hate that I paid so much for this fridge and have to defrost a couple times a year. However found out too late to return back to the store. It seams like it should have a cycle that heats the back plate every so often to warm and evaporate the ice that collects, but I haven't heard or can't find anything on that.

First thing...Take a good look at all the door seals. If they let air and a lot of moisture in, that can condense and freeze causing your problem.
Second...Manualy defrost your freezer and see if the problem re-occurs. It may be that someone left the door open once and caused the icing.

We moved our LG refrigerator and now it (the motor) keeps turning on but won't stay on


On the LG refrigerators, the cause of this is the main control board failing. It is located on the back of the unit under a small access panel. Here is a link to the part you need.

My LG ice maker fan is making a really loud noise right after the water stops going in


Hello, Self-defrosting refrigerators use a circulating fan to move air through the freezer and refrigerator compartment. This fan runs when ever the unit is cooling. The fan is located in the freezer, as follows:
  • If the freezer is on top, the fan is on the back wall,near the top or bottom, in the center of the freezer.
  • If the freezer is on the bottom, the fan is on the back wall, near the top of the freezer.
  • If the freezer is on the left, the fan is on the back wall, half way up or near the top.
Overtime the fan may become noisy, usually making a chirping or squealing sound, though it may make a loud groaning noise instead.
To find out if the fan is causing the noise,just open the freezer door and push in any fan/light switches, if the noise is louder when the door is open, the evaporator fan motor is the cause. You can lubricate or repair this motor. You must replace it.
There are three components on the outside back of the refrigerator that may become noisy: the compressor, the condenser fan motor(if self-defrosting), or the defrost timer (if self-defrosting).
Thanks

Fridge making loud screeching sounds


Generally, in my experience, the loud screeching is caused by one of the fan motors or fan blades. There is a fan inside the cabinet (possiblle two, one on the freezer and one on the refrigerator side). Also, there is a fan underneath the unit near the compressor (probably in the back).

If the screeching is coming from underneath then pull the unit out from the wall and remove the cardboard cover at the bottom back. Now turn the unit on and check for where the screeching is coming from.

If it is the fan blade (hitting something) or the motor, you can remove these and replace them easily. UNPLUG THE REFRIGERATOR BEFORE TOUCHING ANYTHING UNDERNEATH THE BACK OF THE REFRIGERATOR.)

Good Luck!

Loud compressor noise from lg frig...


The sound you hear is the Freezer Fan, this problem is hard to diagnose, because the fan spins but not fast enough to circulate chilled air thru the freezer and refrigerator. The minimum labor and material cost for the repair/replacement is around $300.00. But if you chose to make the repair yourself the motor alone costs around $80.00@appliancefactoryparts.com. But the repair is very labor because the electrical connection for this fan is at the rear of the unit

Freezer making a loud noise.


Sounds as if the evaporator fan has shaft play or the blades are out of balance or striking something. When you open the door the pressure is equal but with the door closed the fan needs to push the air through the evaporator and return again and circle through fan again. I think soon would be a good time to unplug the refrigerator and remove the back panel covering the evaporator and fan motor to inspect the fan, shaft play and the evaporator for frost buildup or any obstruction of air flow.
