If your LG washer has a burning smell, stop using it and unplug the machine before inspecting it. A washing machine burning smell or washer smells like burning is most often caused by a failed rotor and stator kit. Wet stator coils or shorted wires can overheat and smell burnt, especially if the stator is smoking or shows visible damage. Next, inspect the main control board, motor control board, and control board for burn marks caused by a short or power surge. If these boards are damaged, they can produce a washer burning smell and may need replacement. A worn water pump belt is another possibility. It can slip on the pulleys if the pump is difficult to turn, creating friction and a burning odor. Finally, check the drive belt for fraying, wear, or slipping, and make sure the water pump and idler pulley turn freely. A stuck component can overheat the belt and cause a washer smells like burning rubber problem. Enter your LG washer model number to find the exact replacement part for your specific washing machine.
01 - LG Washing Machine Rotor and Stator Kit
The stator is part of a direct drive motor that electrically drives the outer rotor. If the stator coils become wet or the coated wires on the coils short out, they can produce a burning smell. You can test the stator coils with a meter. If the stator is smoking, or smells burnt, it will need to be replaced.

The main control board provides power to the various components of the washer. If the control board receives a power surge, or a component fails, the control board can short-out causing a burning smell. Inspect the control board for burn marks. A burnt main control board will need to be replaced.
The motor control board sends power to the motor. If the motor shorts out or a power surge occurs components on the board can blow out causing a burning smell. Inspect the motor control board for burn marks and replace if necessary.
The control board provides power to the components of the washer. If the control board receives a power surge or a component fails, the control board can short out causing a burning smell. Inspect the control board for burn marks. If the control board is burnt, it will need to be replaced.
The water pump belt can get worn and slip on the pulleys causing a burning smell. Check the motor pulley for wear and make sure the water pump turns freely.
If the drive belt is worn or frayed it can slip on the pulley causing friction and a burning smell. Also check the components the belt is turning to make sure they turn freely. A stuck water pump or idler pulley can create enough friction to cause the belt to burn.
