How to Fix a Direct Drive Motor Coupling for a Washer With a Burning Smell

A burning smell in your washer is typically caused by excess friction. If the problem is with the direct drive motor coupling, it means that the rubber coupling has worn out or failed. This allows the plastic forks to rub against other materials, creating excess friction and a burning smell. You can use the information below to determine if the burning smell from your washer is the result of a failed coupling. When replacing the direct drive motor coupling, be sure to search with your washer’s model number to find the correct coupling for your machine.

What is a Direct Drive Motor Coupling?

Some top-load washers use a direct drive motor coupling to transfer power from the motor to the transmission. This coupling consists of two drive forks made of plastic, one attached to the shaft of the drive motor, and one attached to the input shaft of the transmission. There is a rubber coupling between them that protects the forks by absorbing the torque. Over time, the coupling can wear out and allow those plastic forks to slide and vibrate. The coupling can also get broken when the spin basket is impeded, or if the transmission seizes.

Where is the Direct Drive Motor Coupling Located?

The direct drive motor coupling is attached to the shaft of the drive motor, and the input shaft of the transmission.

How to Access, Remove, and Inspect the Direct Drive Motor Coupling in a Washing Machine

  1. Disconnect the power and water supply.
  2. Open your washer’s cabinet and place the washer on its back.
  3. You may also need to remove the drain pump and/or motor depending on your model. With the motor out of the way, you can access and remove the coupling from the transmission and the motor shaft.
  4. Once you have removed it, inspect your coupling for any signs of damage, wear, or cracking.
  5. If you find any of the above symptoms, you will need a replacement direct drive motor coupling.

How to Install a New Direct Drive Motor Coupling

  1. Push the first piece of the new coupler onto the transmission shaft by tapping it into place, ensuring that it is flush.
  2. Install the round piece of the coupler, and then reattach the motor bracket.
  3. Tap the third and final piece of the coupler onto the motor, and then you can reinstall the motor onto the transmission.
  4. Ensure that the legs on the coupler are inserted into the slots of the round piece.
  5. With all the coupler pieces now connected, clamp the motor back in place and reassemble the washer.
