When your KitchenAid washer won't agitate or spin, the rotor and stator kit is the most likely cause, especially if the washing machine won't agitate or spin and you notice a burning smell. The stator's coils can short or become damaged, preventing the direct-drive motor from turning the rotor. Next, inspect the motor coupling, which connects the drive motor to the transmission and may break from overloading or normal wear. A faulty control board can also stop the motor from receiving power during the wash or spin cycle. If the board and motor test properly, check the drive belt for looseness or damage. A malfunctioning timer is less common, but it can interrupt power to the drive motor after other components check out. Finally, test the lid switch assembly, which prevents spinning when the lid is open. Use a multimeter to check continuity before replacing electrical parts, and unplug the washer before servicing. Enter your model number to find the exact KitchenAid replacement part for your specific washing machine, including the correct rotor and stator kit, motor coupling, control board, belt, timer, or lid switch assembly.
01 - KitchenAid 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 motor coupling connects the motor to the washer transmission. If the washer is overloaded, the motor coupling will fail in order to protect both the motor and transmission. The motor coupling can also fail due to normal wear. Inspect the motor coupling to determine if it is broken. If the motor coupling is broken, replace it.
Since a washing machine control board provides voltage to nearly all of the washer's electrical components, a faulty board may not be sending power to the drive motor during the wash or spin cycle. If power is not reaching the drive motor, you should first confirm the lid or door switch test properly with a multimeter. If the lid or door switch is working properly, the control board is likely at fault. You can inspect the board for signs of burning or a shorted-out component. You can also use a multimeter to test the power output terminals on the board after reviewing the appliance's wiring diagram.
If a washer is not spinning or agitating, you should first determine if the drive motor is running and if power is reaching the drive motor. If no power if reaching the drive motor, and the lid swith assembly or door latch test appropriately with a multimeter, then the timer is likely malfunctioning. Since this is rarely the case, you should confirm all of the other likely defective components are functioning normally before considering a timer replacement.
06 - KitchenAid Washing Machine Lid Switch Assembly
The lid switch assembly prevents the washer from spinning when the lid is open. If the lid switch assembly fails, the washer will not spin. To determine if the lid switch assembly is defective, use a multimeter to test the lid switch for continuity. If the lid switch does not have continuity, replace it.
