Why does the refridgerator sounds like a jackhammer?

SOURCE: FREEZER SOUNDS VERY NOISY

Fridge problem could be the fan is bad or that it is hitting ice. When the noise is kind of a buzzing like it is hitting ice...defrost your unit by unplugging and waiting a day or so for full melt out...then check your door gaskets for cleanliness and good seal.

Thanks.

There is a good chance this is the culprit.

Servicing the Evaporator Fan

In some cases, a faulty thermostat may not be the cause of a warm refrigerator or freezer. A warm box may also be caused by a defective fan, a blocked fan, or broken or bent fan blades. If the blades are jammed, try to free them. If they're bent, straighten them with pliers. If this doesn't solve the problem, call a professional service person.

On some refrigerators, the door switch operates the evaporator fan. If the fan seems to be malfunctioning, the door switch could be faulty. Test the switch as detailed in the last page, and replace it if necessary.

check gaskets for air leaks or blocked drain in freezer section

Sounds like a fan motor inside the machine is failing.
I don't know where you live but in our area, LG has denied anyone but an LG dealer parts. You can check that out but you might use that as a guideline. It's sad here since we can't get parts we don't bother running calls and have little experience with their machines.
