You may need to know how to troubleshoot a washer timer switch if your washer is not advancing through the cycles. Signs that you may have a faulty timer switch are missing cycles, stalling in the middle of cycles or the timer simply not advancing through the cycles. You will need to refer to the cycle sequence chart for your model to determine which contacts to troubleshoot. The sequence chart is in your owner's manual and stamped inside your washer control console.
Disconnect the washer from the wall outlet. Pull the washer away from the wall to allow the control console to sit back in the service position.
Use a Phillips head screwdriver to remove the screws that secure the control console to the washer top. Some washers use retaining clips to secure the control console. To disengage the retaining clips, slide the blade of a putty knife under the front corners of the control console and lift up the corner with your hands. Flip the control console backwards to set it in the service position.
Locate the timer on your washer. The timer is usually on the right side and it will be behind the front timer knob. Disconnect the wiring harness going to the timer. To disconnect the harness, press in on the plastic locking tab and pull the harness away from the washer.
Inspect the contacts of the timer. If they appear to be burnt or damaged the timer is faulty.
Set the scale on a volt-ohm meter to the RX1 setting to test the timer contacts for continuity. There is a cycle sequence chart stamped on the side of the timer or attached to the back of the control console. Refer to the chart for what contact points to test for any cycle.
Touch the two probes of the volt-ohm meter to the contact points to be tested. Turn the dial of the timer to the appropriate cycle that is being tested. There should be no continuity reading on the volt-ohm meter during the test. If there is a reading on the volt-ohm meter, the timer is faulty.
