Question about LG Bottom Freezer Refrigerator w/ Swing Freezer Door 22 Cu. Ft. - LRBN22514
I have an LG model LBN22515st and I noticed that the fridge wasn't cooling properly. However, the freezer was working fine. I saw there was quite a bit of frost/ice on the back of the freezer. So, I took everything out unplugged it and let it defrost. In addition, I looked behind the unit and it was FULL of dust. I cleaned everything out behind the back panel. I plugged it back in and when I let it sit for 8 hours the fridge was still not cold but the freezer was. Can anyone tell me what part I need ? ?

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.

The problem is ice build up on the back wall. The noise you hear is the fan blades hitting the ice. On the back wall water gets trapped, it then builds up over time, and a big ball of ice forms and blocks the fan. Take off the back wall, defrost the build up and cut the insulation off as above. The water will no longer get trapped and the problem will not come back.

I had the same problem. LG came and fixed it in about an hour. Replaced the circuit board with an updated one and swapped out some sensor. Seems to work now and it was all under the 2 year warranty.

Locate your defrost timer, they are either in the buttom front of the refrigerator, in back of the refrigerator, or inside compartment behind the plastic covers. On the defrost timer there is a slot were it can be turned using a screwdriver, or there is a round window were you can see it running.when you turn this dial and it clicks, you should now go into defrost. with all the ice build up in your evaporator you should hear the ice cracking indicating that the heaters are working, if not you might have open defrost heaters.

Sounds like the freezer fan(FF)is wearing out, This problem is very hard to diagnose because the fan spins but not fast enough to circulate the chilled air thru the freezer and refrigerator. This repair costs parts and labor around $300.00
