Question about LG Refrigerators

1 Answer

Hello, our LG GR-389STQ fridge is 16 years old. It has worked well all along. Now a sheet of ice regularly forms at the bottom of the freezer. I have seen videos explaining that it is likely a clogged drain, but I can't identify it in our fridge. Could anyone possibly help?

Only frost free models have a drain and that is recognisable by a funnel shaped moulding in the plastic of the cabinet liner terminating in a hole.

Frost free models have a heating element that is switched on briefly after each cooling cycle, melting any ice that has formed over the evaporator. The resulting water droplets are channeled into the drain by the funnel-shaped moulding. The drain leads to a tray fixed to the compressor and the heat from the compressor causes the water to evaporate.

The best thing to check if the drain is clear is a flexible curtain wire and for a good clean a variety of suitably sized brushes are available.
Sometimes the insulation of a fridge or freezer becomes sodden with water and ice tends to build over that area. Where the drain runs through an area of sodden insulation where ice is forming it can be impossible to clear the drain.

Check the outside of the cabinet for cold spots. The presence of a cold spot indicates the insulation is failing and it is time to replace...

SOURCE: clogged fridge drain tube

The drain is behind the back panel in the freezer at the bottom. Sounds like it is frozen over which is pretty common. Will need to remove panel and thaw out drain by running hot water down. You can use a putty knife to break up ice first. Make sure you get all ice around the drain above and below the thin aluminum tray at the bottom. After the drain is free don't be alarmed if you get some water on the floor because the drain pan may not hold all of the water you ran down the drain. Not anything you can do to prevent this on this model.

Defrost the unit for two days with the doors open...I know you're going to lose your contents. You may have ice on the coils internally. Next make sure you've cleaned the external coils under the unit. Leaving liquids open inside the unit or setting it colder than required will both cause issues like the ones you've got. Also, be sure all air vents inside the unit are unblocked and the door closes tightly all around.

SOURCE: lg frost free fridge freezer gr-399sq

on the back wall inside the freezer unscrew the white panel and then remove the panel behind this . you should now see a tray that runs the width of the freezer with a driphole on the left-hand side which will probably be frozen with ice , chip away whatever is possible and then put boiling water on the driphole and once this is clear you should find the problem sorted , 1 other option is to turn the fridge/freezer off for several days and this will allow the ice build-up to thaw thus resolving the problem

SOURCE: sheet of ice forms in bottom of freezer

Frost free fidges are supposed to stay frost free because the automatically defrost regularly. When they do this they may drain water down to the bottom of your fridge. Look for a tray that catches this water underneath the unit. Make sure yo keep it emptied. If you live in a very warm climate you may be getting a lot of humidity inside. There may be a switch that you can change for lower moisture.

I have a LG fridge model GR-P247STSL and the ice maker is not working. The plastic arm that determines whether the ice bucket needs replenishing is not coming down. Do you know why?


*Check your warranty. You should call vendor for service.
*** The following is for information only.**
* I've had this problem a lot with my old fridge. Water line works but no ice.
* Check if the "Ice Full" leaver is in the down (no ice) position. Some ice makers will lock the leaver (a stiff wire) in the full position to manually shut off ice maker. Make sure it swings up and down when ice tray is empty.
* Sometimes when the tray is left full of ice for a week or more then the tube feeding water will freeze up. Defrosting the freezer on a regular basis will help. A quick fix is to pour warm water in the ice maker section (where the ice is formed). This will help melt the clogged pipe and also make some ice while your waiting. You may have to do this several times. But at least you have ice.
* This (freezing up) may also be caused by the freezer set too cold. The temperature dial should be in the middle. But turning it colder and colder over time will cause ice to build up and prevent foods from freezing properly (thus turning the dial down colder.) Once your maxed out on the dial. You will find the freezer gets warm and things get covered in frost crystals.
* Transfer food to another refrigerator and perform a complete defrost by leaving it unplugged and the door open (freezer section).
* Frequently check and dump water at bottom of fridge. Clean the dust on coils while down there.
* A fan blowing into the freezer section helps. (Do NOT use a heated fan as it will warp the plastic and overpressure the refrigerate.)
* Once defrosted (+4 hours). Power up the freezer and set the temperature dial to mid point and the freezer diverter to middle or normal setting. Don't put the food back in yet. Wait till the freezer gets down to normal freeze temp (about 0 to 10F)
* Move freezer back in place (if you moved it to access plug) then slowly put back the food. Try not to cram stuff in. Leave space for air to flow freely around items.
* Final, Call for service anyway and have them perform yearly service. Check your warranty.
