Question about LG LRBN20510WW Bottom Freezer Refrigerator

1 Answer

Model LG LFX25971ST bottom freezer refrigerator - Purchased in 6/08 - Started hearing a loud knocking noise periodically. Had numerous service calls ending in replacing the ice maker twice and replacing the water valves, and the last service tech taped up the lines in the back thinking that was the issue. Nothing has solved the problem. I noticed when the compressor came on I would hear the knocking noise about 10 seconds after. Another tech came out today and even called LG tech assistance and they do not have a resolution to this very annoying problem. The noise even wakes us up in the middle of the night. I appreciate any help or suggestions you may offer.

Error code er rf

Hello George;
My name is Peter. I am a retired field service refrigeration technician.

The error code is either a bad freezer fan, which is more likely, or a bad control board.
25682632-ebcjyrvherokzlkldixpqrtk-2-0.jpg Motor Part Substitution: 4681JB1027C Cost: $55.00
Part #: EBR41956418 Cost: $125.00
There is a reset button on the board located in the back of your unit. GROUND YOURSELF BY TOUCHING SOMETHING THAT IS BARE METAL. STATIC ELECTRICITY WILL KNOCK OUT A CONTROL BOARD. Push the reset button only once. Open the refrigerator door while holding the light switch button in. Hear the fan?
Go into the following website, put in your model number and select parts. Parts and diagrams will appear.

You can purchase the parts for allot less over the internet.
If you call a service company, they will double the cost of the part and probably charge you $250.00 or more for labor. The labor cost for a bottom freezer is allot higher than a side x side or top freezer because of the difficulty to access the freezer components.

Bottom freezers and units with the ice maker or ice bucket on the door are the worst.
On my daily service calls, 65% were for either Samsung or LG.
Next time stay away from these and the above.

Freezer Problem

Compressor may be bad - do you hear motor running??? It may need freon. Airflow may be blocked -- keep area clear just like intake vents on floor, must be kept clear to allow proper air flow.

Interior lights would not turn off. after

You need a new main board. The relay on the board is stuck shut. Call LG customer support and ask about a recall. The board is free but, you will have to pay service call charge.
