How to Fix a Selector Switch for a Washer That Will Not Agitate

If your washer selector switch is faulty, it may prevent the motor from starting. Without a running motor, the washer won’t be able to agitate. To figure out if the selector switch is at fault, you need to test it with a multimeter. The information below will walk you through this process, along with how to replace the switch, if necessary.

What is a Selector Switch? Where is it Located?

Some washing machines control the speed of the drive motor via a selector switch. These switches are also used to select the appropriate cycle or function for the washer. The selector switch is found on the control panel of your washing machine.

How to Tell if the Selector Switch is Damaged

If the switch is defective, it may stop the motor from operating. You can test if this part is defective by checking for continuity with your multimeter. You can isolate the correct terminals to check by consulting your model’s wiring schematic.

How to Test the Selector Switch in a Washer with a Multimeter

1. Unplug your washing machine before beginning, as you will be handling electrical components.
2. Locate and remove the selector switch from your appliance. It likely is secured to the frame of the washing machine. You need to remove all or part of your washer’s cabinet to access it.
3. Using a multi-meter on the Rx1 setting, test one button at a time for continuity. Touch the probes to the terminals and press in on the first button. The reading should change from infinity to zero. Keeping the probes connected to the terminals, press in on another button, and the reading should go back to infinity.
4. If your test results differ from those above, you need a replacement selector switch.

How to Access and Remove the Selector Switch

1. Remove the selector switch from the unit, which is most likely secured to the door frame with a few screws.
2. The terminals extending from the body of the switch are grouped in pairs of two, one group of terminals for each button. Each group must have its wires removed for testing.
3. Carefully remove the wiring harness leads from the first pair of terminals of the switch.
4. Do not pull on the wire itself. Needle nose pliers may be needed to remove the wire from the terminal.

How to Install a New Selector Switch

1. Attach the wires to the terminals of the new switch.
2. Secure the new switch to the washing machine.
3. Feel free to use the screws from the original switch.
