If your LG freezer is suposed to be "frost free" it may have a blocked defrost water outlet.

SOURCE: Frost buildup on ice/water dispenser

Is the trap door flap closing properly where the ice comes through the door? If open, warm air would be coming in frosting and maybe iceing things up

SOURCE: Hotpoint FFA70 - Freezer door will not close properly.

The rear panel can be removed,i have done it.I removed the 4 hex head screws from the top & bottom of the panel,and firmly pulled it forward.The reason i say pulled firmly is that when panel came out the back of the freezer was solid with ice.I have defrosted the freezer,dried any water from the unit and replaced the panel.Fingers crossed,so far,so good.In my case this build up of ice was definately the reason the drawers were not sitting in the correct position,as it caused the rear panel to 'bulge' out.Hope this helps.....

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.

Where is the ice maker fan for LG French Door Refrigerator?

Hello,

The ice maker fan is located in the freezer and is part of the Grille Assembly ( LG part Name) Which is the removable back panel in the freezer. If you have an error code on the display such as ER/IF the fan is not rotating due to failure or ice accumulation in the fan blade. If you have no error code and the ice maker is not producing ice 2 things to check are...1. On the bottom of the ice maker there is a Test Button. Press and hold the button and the ice maker should rotate, Dump ice cubes and refill with water. If the ice maker does not cycle replace the ice maker. 2. Check freezer temperature. Freezer Temperature must be below 15 degrees to make ice. Ideally freezer temp should be 0 Degrees. If you have warm temps in the freezer there may be a sealed system issue preventing proper cooling.

Hope this helps.

Icing up

I've just had a similar problem. I fixed it by removing the large panel on the back of the inside of the freezer. I found a large build up of ice at the bottom of the freezer which seems to have developed because the drain hole at the bottom of the freezer was blocked. I defrosted the ice, cleared the drain and now the freezer is working fine.

Large amount of ice has accumulated behind the back panel in the upper part of the unit on my Sante Fe RX. About 2 to 3 inches thick.

Your post says you have an RX but the picture shows a SantaFe Classic.
In either case the massive frost build up is caused by a defective defrost thermostat. PN 4021470 Parts Dept 800-533-7533 x 8451
The defrost thermostat has an internal set of electrical contacts that are designed to open up and turn the compressor off when frost or ice has accumulated on the tubing and the evaporator coil. If the contacts fail to open, the compressor keeps running and the frost and ice just keep accumulating until such time as the homeowner unplugs the unit or a sevice tech replaces the defrost t-stat.

Ice crystals forming on inside front freezer panel

Very possible the door seal is not properly sealed. Warm inflowing air onto a cold coil will cause ice build up at the lid.

Bottom Freezer has ice built up

Possibly the defrost element is faulty, this is located behind a cover in the back of the freezer compartment and is attached to the fins of the evaporator. It also has a defrost limit thermostat which could also be the problem. I presume that the fan is working after you have defrosted the unit?

I am accumulating ice inside my freezer

It needs to be defrosted. If ice builds up quickly again then start shopping for another freezer as the repair is not worth it. I cannot see your repyl due to some tech issue w/ the site, so it may be a day or so before I can reply again. Please leave feedback for me if appropriate. Thanks
