SOURCE: LG refrigerator makes loud noise and then stops running.

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.

If the fan has failed or intermittent, the freezer wont freeze the food properly but usually you get a mountain of ice build up at the back of the freezer. This ice jams and stops the fan from turning. Alternatively, there could be a defrost problem. Unless it is a fully electronic defrost machine, there is usually a little timer on the back of the fridge to force a defrost after a certain time. The fridge will turn off, the defrost heater operates to melt the ice and then usually with 20 to 45 minutes, the defrost timer will "click" back on and start the fridge running again. If the timer is sticking, the fridge may stay on its defrost cycle and never start again, thus, it doesn't get cold. If you find the defrost timer, have a close look for a little shaft or slotted screw type stud sticking out of the middle of it. A slight turn of this and you should hear it clicking around. When you hear a loud click, that is either the start or end of the defrost cycle. If you have a full electronic defrost system, it may be a failed board, heater, thermostat or defrost safety fuse.

Every 20 minutes, my freezer would make a crackling like noise. What does this mean and how can I fix this?


Refrigerators are not the most complicated appliance in the house, but it still takes a lot of parts working together perfectly to keep your food cold. If one of those parts breaks down, or begins to, you may start to hear new noises from your refrigerator. Fridges make some noise during regular operation, but if it suddenly gets louder or makes a different noise, it is a good sign that something is wrong.

Freezer Fan
Freezers can be located on either side of the refrigerator, or may be at the top or the bottom of the unit. If you hear a noise coming from the area in which the freezer is located, you should open the freezer and see if the noise gets louder. Any squealing sounds coming from this area indicate a broken freezer fan. These units are not designed to be repaired, and eventually one making a loud noise will break and need replacement.

Condenser Fan
All motors typically require a fan in order to maintain a safe operating temperature. Like the fan in the freezer, the fan that runs on the condenser can also break down and create a similar squealing noise. The location of the fan noise is what differentiates the freezer and condenser fan problems. If you hear a fan noise coming from the lower part of the fridge at the rear, it is likely the condenser fan causing the problem.

Action to do
Open the freezer to see if the noise gets louder. If the noise becomes louder with the freezer open, the noise is likely caused by the evaporator fan. If the evaporator fan is the culprit, replace it to get rid of the noise.

Pull the refrigerator away from the wall, and check the condenser fan at the back of the fridge. A metal panel may cover the fan, which can be unscrewed. Listen to see if the fan is the source of the noise. If it is, the fan may need to be cleaned or replaced.

Thanks for using FixYa.

Good day ! : )

Fridge working off/on


If the noise was coming from the compressor when it was cutting off or starting, it was the internal mounts of the compressor and the compressor will have to be replaced. If the noise was a fan, it may have stopped. One is in the freezer behind the rear cover and one is underneath where the compressor is behind the cardboard cover.

It sounds like the evaporator fan is hitting ice that is built up on the evaporator coil. When it's making the noise, open the freezer door and see if it stops.
(Most models are wired so that the evaporator fan cuts off when the freezer door is open.)
Check the inside back, lower panel of the freezer for ice built up or frost on it. If there is, you have a defrost problem that is most likley a bad heater. It's located around the coil inside the freezer behind the panel you will be looking at. The defrost problem would explain the freezer not freezing ice cream.

Our LG bottom freezer refridgerator is 2 years old. It is making a whirring noise that stops when the door is opened. It can get pretty loud at times.


The whirring sound is the fan that blows cold air into the refrigerator. It is supposed to stop when the door is opened. If it is making a loud noise there may be ice built up in the fan housing. Turning the power to the refrigerator off for a 2-4 hours may allow any ice in the fan to melt. If you do not open the freezer during that time the frozen food will not defrost.If the noise continues, you may have to take the fan apart to make sure it is not frozen. It is probably located behind the back inside panel of the freezer.

REFRIGERATOR AND FREEZER UPPER HALF NOT COLD


If you live in a humid area, I'll bet ice buildup is screwing with the air flow. I have a similar, but less intense problem. So in my case, simply unplugging the fridge and letting all the hidden internal ice melt solves it for several months. GE sells a "moisture kit" which I refuse to buy, since it's $340! Plus, I doubt it will fix anything. Good luck!
