I have the following fridge:  LG LFX31925ST Fridge --

symptoms:
-on the upper middle part of back wall of the freezer there was ice in the middle 2" thick ice, picture down below
-the two small slide out drawer fronts also started to get ice deposits on the handles
-fridge: is working fine, things are cold, temp set at 33F
-freezer:  items are frozen as well, temp set at -1F
-fridge is about 9 years old

so what can this issue be?

Hi,


Could be a possible air leak. Outside air leaks into the freezer and then the moisture that is in the air condensates and freezes.
I have not work on this particular model of LG myself. Maybe one of our other forum members will chime in with some additional advice.


How old is the refrigerator?

Hi.  Thanks for replying. 
I did look at the seal, it looks like it's all touching really well.
I can't slide paper in between...i tried card stock, can't get that in either
i can get the card stock to slide in from a corner, but there seems to be a good pressure when sliding it around.

I see now you originally posted it's 9 years old. Beside the door gasket another place to check for air leaks would be any place say a water line (if it has a ice maker) or the refrigeration lines enter the freezer.

How long has it been a problem? Any chance the door just didn't get closed all the way one time?

the ice maker is in the door in the fridge.

i did open up the back, and cleaned out the coils, lots of dust there.

i've cleaned out the inside, and the fridge was turned off yesterday.

i'm not sure on that the door was left open.   i've removed everything, and have been running the fridge again, 
i'll see tomorrow if i get build up again.

i'll check for the lines entering again to see if there are leaks there.

i'm also going to remove the inside cover and see if there is ice build up on the coils....

i'm gong to let the fridge run for a couple days without opening the lower part and see what i find and report back

There are frost crystals all over inside the freezer, that indicates door not closing properly over an extended period of time. Clear the ice and wipe everything dry for future diagnosis. Over packing bottom freezers is a problem with door closures. Ice and water will also build on rails, be nice to those and dry also ~ you can use a CRC food grade silicone spray on rails to help resist water droplets and freezing rails.
