Ice accumulates in bottom of freeze compartment of my LG frig

We have ice that accumulates in the bottom of the freezer compartment. I have the tpy ewith a lower freezer drawer. After about a week it get to the level that the drawer is difficult to remove and we have to chip the ice out.

Additionally, the water appears to be coming from the back in the freezer compartment through the vents that cool the freezer and it also builds up and eventually makes the fan stop working which causes us to have to thaw overnight. After the thaw the fan works again and all is Ok .... until the next time. and we have to repeat this all over again.

I disconnected the water feed and all is well, no ice , fan seems fine as well but we would really like to have the water dispenser.

Where can I look to try to find and fix the leak?

SOURCE: Freezer works fine refridgerator does not

anan, I think your display is giving you a code on these LG. See if you can find the tech sheet behind the toe panel. On your display panel from memory, 3 led's lit from the left means a failed defrost thermistor. This could be the reason you are frosting up and restricting the air flow. There is a main board in back that you can ohm out the thermistors. Connector 4, the two bright orange wires #5 and 6, should ohm at 19K ohms at 50 degrees. Now Im doing this from memory, if you can find your tech sheet, it will give you precise information. Catriver.

SOURCE: water pooling and freezing inside bottom freezer

I had the same problem with my LRFC25750 and have finally figured out what's happening! The water that is pooling and freezing on the bottom of the freezer is definitely coming from the defrost cycle. It is pooling inside the freezer compartment because the drain inside the back of the freezer intended to carry the defrost water down to the external evaporator tray underneath is blocked with ice. As a result, the defrost water from the coils overflows the collector under the coils and runs down the inside back of the freezer, pools on the bottom, and re-freezes when the cycle is over. this continues until there's so much ice on the bottom that the water from next defrost cycle runs out on the floor. The "easy" solution is to unplug the unit and let it completely melt out (this could take 24-36 hours). I couldn't wait, so I removed the freezer drawers and their tracks and pulled out the back panel inside the freezer -- saw the ice in the collector and blocking the drain and I melted it away with hot water and verified that water could now flow down to the external evaporator tray. Unless you want to do this, I'd say give it a good 24-36 hours for all the ice to melt away. I think it all started when we left the freezer door ajar for a whole day and probably had a lot of frost build-up on the coils. The next defrost cycle was not enough to clear all the frost and things began to build up from there. Once the drain is frozen, though, you're finished -- the defrost heater doesn;t reach down that far and you have to melt it down completely or it will continue to leak forever. I've heard that you can get a drain heater to ensure that the drain never freezes over or at least so that it is sure to clear with each defrost cycle. I'll post an update if I locate one.

SOURCE: LG ice maker only making two ice cubes at a time

Colenoid in the ice dispenser may be clogged or have a small amount of trash in it. Is there a filter on before the fridge (just after the ice maker shutoff)?

SOURCE: freezer compartment thaws out

Hi and welcome to Fixya. Once the defrost cycle is started it deos not terminate until the 60 Deg. F thermostat closes and advances the defrost timer to start the compressor. If the 60 Deg F thermostat is not functioning correctly or intermittent the unit will continue in the defrost cycle by powering the defrost heating element. Essentially what it will do is act like a food defroster vs a freezer. This is not a difficult or expensive repair.

I would recommend that the defrost thermostat be tested for proper function. Personally I would just replace it and return the unit back to normal service.

Additionally it is possible that the defrost timer could be hanging or sticking in the defrost mode.

Should you call a technician to repair the unit I am sure he would recommend the replacement of both the Defrost timer and the 60 Deg F thermostat.

I would also recommend the same to you during in home repair service. Thanks again and hopefully you understand why it is performing as it currently is.

Your defrost drain line is probably plugged up and water is overflowing from the drain tray. if you can locate the hose where it leaves the refrigerator at the bottom of the unit you can blow air into the line and clear it out from there. if you can't get to the line from there, you'll have to pull the evaporator cover off in the freezer and clean the tray and line from there.ad

Ice, the size of a small fist accumulates behind the rear freezer panel area behind the ice maker and just above the fan. What could cause this ice build up where there are no coils?

There are a few possible reasons for the ice build-up in the area behind the ice maker and above the fan, even if there are no visible coils in that area. Here are some potential causes to consider:
  1. Blocked Drain: The defrost cycle of a refrigerator is designed to remove excess moisture from the freezer compartment, which typically drains out of the freezer through a small drain hole and into a collection pan located beneath the refrigerator. If the drain becomes blocked, the excess moisture can accumulate in the bottom of the freezer and eventually freeze, leading to the ice build-up you described. To check if this is the case, you can try locating the drain hole (usually near the back of the freezer, near the bottom) and clearing any debris or ice that may be obstructing it.
  2. Faulty Defrost System: Another possibility is that there is an issue with the defrost system itself. If the defrost heater, thermostat, or timer is not functioning correctly, it can lead to excessive ice build-up in the freezer compartment. While you mentioned that the coils appear to be defrosted, it's still possible that there is a problem with one of these components that is causing the ice to accumulate in a different area.
  3. Poor Air Circulation: A third potential cause is that there is inadequate air circulation in the freezer compartment. If the freezer is too full or if items are blocking the vents, it can prevent cold air from circulating properly, leading to pockets of warmer air that can cause excess moisture to accumulate and freeze. It's worth checking to make sure that the freezer is not over-packed and that there is nothing blocking the vents.
  4. Water Leak: Finally, it's possible that there is a water leak somewhere in the refrigerator that is causing excess moisture to accumulate in the freezer compartment. This could be due to a damaged water line or valve, a faulty ice maker, or a damaged door seal that is allowing warm, humid air to enter the freezer. If you suspect a water leak may be the cause, it's best to have a professional diagnose and repair the issue.
Overall, it's hard to say for sure what is causing the ice build-up without further inspection, but these are some common possibilities to consider. If the issue persists, it may be worth calling a professional to diagnose and repair the problem.

LG LFX28978 Refrigerator, freezer not cold enough, maintaing temp at 40-41 degrees.

How did you remove ice from freezer. If you uses any type of tool (Scraper etc) then you have possibly punctured the evaporator tubes. These tubes can be either as a radiator type or form part of the freezer box and are very thin therefore susceptible to puncturing when using scrapers or such to remove ice.
To remove ice from refrigerator condensers allow it to melt, you can use a hair dryer to speed this up but DO NOT use mechanical means.

My bottom drawer freezer is accumulating a sheet of ice

Your defrost drain line is clogged or frozen so the defrosted water is leaking into the freezer compartment and freezing into a ice layer in the next cooling cycle. Get your defrost drain line unclogged.

Water pools and freezes at bottom of the freezer. When tray is full water leaks out of freezer onto kitchen floor.

I am uncertain as to what you mean by "when tray is full"? However, you probably have a clogged drain in the freezer compartment. During the defrost cycle, which usually occurs every eight hours, defrost components (defrost thermostat & heater(s) ) melt the ice that has accumulated on the evaporator coil in the freezer compartment. The water from the melted ice drains through a hole in the freezer compartment (behind the freezer's rear panel) and accumulates in a drain pan below the refrigerator. This water should evaporate over time, whereby you should not have to regularly empty the drain pan. If the drain hole is clogged (usually from algae or other debris, etc.), the water finds another path to flow (which is inside the bottom of your freezer compartment). This water will usually freeze. Water will then flow toward the front of your freezer compartment and out of the door on to the floor when you open the door.

Contact an appliance service company to unclog your freezer drain. Also have them check your defrost components (thermostat & heater(s)).

Every few weeks the ice in my freezer melts. It

You will need to remove the bottom freezer crisper and check the defrost drain , to see if it is iced over . If so , then use a hairdryer to melt the ice ( hot water also helps ) . When you see the drain , ( could be obvious obstruction from plastic ) , use a small hose inserted into the hole , to blow thru , to remove any unseen debris blockage .
You may have to remove the rear inside freezer panel to access this drain , depending on your model number . So make sure the drainhole is open. When it happened to mine this was the problem.

your refrig. goes through a periodic defrost cycle whereby this water is produced. It is supposed to travel down to the evaporation pan near the floor of the frig. Your evaportation pan may be clogged, remove the front lower panel and get a flashlight and examine it., or the tube leading from the freezer floor may be clogged or have ice it it. Check that out and if the opening of the tube has ice in it, melt it with a hair blow dryer

Water/freezing to ice at the bottom of the freezer MZD2766ge

sounds like a drain clog in the freezer compartment above. remove the freezer rear panel and totally defrost the evaporator area, directly under the evap you see( under all that ice) a small drain hole that has become frozen over, try defrosting with either a hair dryer( not a heat gun too much heat youll melt everything) or by pouring hot water down the drain until you get a free flow of water down the tube. after its clear reassemble and you should be fine

Water acculation in refridgerator.

I had a similar problem with my old hotpoint frig (top freezer, bottom frig). the defrost cycle would come on and melt the ice, but since the drain plug in the back of the freezer below the coils would eventually freeze up closed due to ice accumulation. It got to the point I had to shut down the whole unit and leave it open for around 8 hours to let it naturally melt the ice in the drain tube. I hear a gurgle sound and then a sound of water flowing, so I knew it was now draining again.
