How to Replace the Shift Actuator in Your Whirlpool Washer

The shift actuator in your Whirlpool washer model WTW4855HW is found at the bottom of your appliance. Its main job is shifting your washer from agitate to spin. A faulty actuator can stop your machine from entering the spin cycle. Replacing the failed component is a fairly easy repair job that shouldn’t take much more than an hour.

How to Replace a Damaged Shift Actuator in Your Whirlpool Washer

To avoid electrocution, unplug your washer from the wall and turn off its hot and cold water supply valves. Protecting your eyes and hands by wearing safety goggles and work gloves is highly recommended during any type of appliance repair.

  1. Pull your washer away from the wall and remove the water supply line connected to the inlet valves on the back of your machine. Have a towel handy to wipe up any water that may drip out. Then, loosen the clamp holding the drain hose in place, and detach the hose from the drain hose shaft.
  2. Move to the front of your washer, and tape its lid down. Place a large towel on the floor and tilt the washing machine backwards to lay the appliance on its rear panel.
  3. Now that you’ve gained access to the bottom of your washer, you can start removing the faulty shift actuator. To do so, first take off the cover that protects the motor and drive components. Then, disconnect the actuator wire harness, and remove the screws securing the shift actuator to your washing machine. Pull the actuator off the bottom of your appliance and set it aside.
  4. Retrieve your new shift actuator and install it by securing the part to the gear case and inserting the actuator arm into the shift lever. Add the mounting screws to hold the component in place, and then, reconnect the actuator wire harness.
  5. Reattach the plastic cover to the bottom of your washer. Next, stand your appliance up, and take the tape off its lid.
  6. Reconnect the water supply lines to the inlet valves on the back of your machine, and reattach the drain hose to drain hose shaft. Make sure you slide the hose clamp up to secure the drain hose connection.
  7. Resituate your washer near your laundry room wall. Finish up your repair by plugging your appliance back in, and turning on the hot and cold water supply valves.
