Below is a posting from a few days ago about a fan problem that is causing my LG fridge to stop cooling. Wiz offered some ideas, most of which I answered below, and I never heard from him again.
From what I can tell there is ice build up behind the freezer wall causing the fan to stop working. I don't know how to get behind the back wall and if I need to take the ice maker off in the process. The wall near the ice maker is pushing forward more than the other side indicating ice build up near the ice maker. Maybe a leak.
Any ideas?

LG Model lrbc22522st:
After noise starts I defrost the back wall of freezer with warm water and or hair dryer.
But within weeks the noise returns. I read on your site (I think) about
cutting away some insulation to give the fan more room but I don't know
how to get to the fan. I was unclear how to remove the back wall of the
freezer and if I had to also remove the icemaker as well.
Could there be a leak of some kind behind the freezer wall causing ice buildup and fan interuption?
Any help would be appreciated.

Hello and thanks for the suggestions.
· Hissing and popping is normal on frost free refrigerators, it is the defrost heater
The noise is not hissing or popping. It sounds like a fan blade
hitting something. It only makes the sound when the circulating fan is
on.
· Check that the refrigerator is level
Fridge is level.
· Check the drain pan
Drain pan is fine.
· Check the condensor fan
I cleaned the condensor fan and it works fine.
· Check the evaporator fan
I think the evaporator fan is the fan I was referring to. Is it the fan that circulates cold air into the refrigerator
compartment from the freezer? If so, that is the fan that can get
encumbered by ice and icy insulation preventing cold air from getting
into the refrigerator compartment. So cutting away the insulation would
be a solution. Is this the same fan?
· Inspect the compressor mounts
I will inspect these this evening.
Since this issue is repeating on various models, I point you here to a manual (with images) that explains how to fix this frozen fan / drain pipe. Here is the manual by Avi Remember, manual 24h defrost is the easiest thing to do b4 you take more actions. good luck Avi
You have a defrost system failure and needs to be checked.
You can manually defrost for a temp fix. Turn it off, take everything out of the freezer, use a hairdryer to warm the back wall, 20-30 min, put everything back, turn it back on and you should be good for a couple of days.

Mine is doing the same thing. I'm defrosting it overnight and cutting away the foam a little bit to see if that helps. Anything else I should do?
