How to Fix a Transmission Actuator for a Washer That Has Spinning Issues

A damaged or defective actuator can cause your washer to fail to spin. If the actuator is defective, you may notice that your washer drum is also not agitating and is making a clicking or grinding noise. This simple guide will help you figure out if the actuator is responsible for your washer not spinning and what steps you will need to take to repair it. In some cases, the actuator may no longer be usable, and you will need a new one. We will show you how to install a replacement part and restore your washer to full working condition.

What is a Transmission Actuator?

The actuator, also known as a shift actuator or a transmission actuator, changes the transmission from agitation to spin mode. The actuator shifts the clutch and monitors the clutch position, sending information on speed and direction to the motor control board.

Where is the Transmission Actuator Located?

The actuator is found at the bottom of the washing machine, typically mounted to the transmission.

FIX TIP

Remember that before handling any electronic appliances to disconnect the power source from your appliance before beginning to avoid electrocution.

How to Access, Remove, and Inspect a Transmission Actuator

1. In order to access the actuator, first disconnect the water and power supply, then lay the washer on its back.
2. It is easiest to access the actuator if you first remove the pulley cover.
3. You can then remove the screws holding the actuator assembly in place.
4. Then remove the wire harness and discard the old actuator.

How to Test a Transmission Actuator

1. You'll want to use your multimeter to check for electrical continuity. If the actuator is not showing continuous power, you will need to replace it.
2. Set your multimeter to the Rx1 setting, and touch the probes to the terminals. If there is continuity, the multimeter should show a reading of zero or nearly zero.
3. If your test produces a different result, you'll need a replacement shift actuator.

How to Install a New Washer Transmission Actuator

1. To install a new actuator, first connect it to the wire harness.
2. Make sure that the sensor fits into the opening, using the two locating pins as a guide. Then secure it in place with the two screws.
3. The timer or control board may require calibration. Information on how to do this in most cases comes with the new part.
