A washer burning smell from a Speed Queen Commercial washing machine usually points to an electrical or belt problem, so unplug the machine before inspecting it. The most likely cause is a faulty rotor and stator kit. Wet stator coils or shorted coated wires can create a washing machine burning smell, and a smoking or visibly burnt stator should be replaced. Next, inspect the main control board, motor control board, and control board for burn marks caused by a power surge or failed component. If the odor smells like burning rubber, check the water pump belt for wear or slipping, and make sure the motor pulley and water pump turn freely. A worn or frayed drive belt can also slip against the pulley, creating friction and a washer burning smell. Check for a seized water pump or idler pulley before installing a new belt. Enter your Speed Queen Commercial washer's model number to find the exact replacement part for your specific washing machine, including the correct rotor and stator kit, control board, water pump belt, or drive belt.
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.

02 - Speed Queen Commercial Washing Machine Main Control Board
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.
03 - Speed Queen Commercial Washing Machine Motor Control Board
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.
04 - Speed Queen Commercial Washing Machine Control Board
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.
05 - Speed Queen Commercial Washing Machine Water Pump Belt
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.
06 - Speed Queen Commercial Washing Machine Drive Belt
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.
