Why my Kenmore Series 400 triple agitator washer won't start.

Cause 1

User Control and Display Board

To determine if the user control and display board is defective, try pressing the buttons on the control panel. If some of the buttons work, but others do not work, the control and display board might need to be replaced. Additionally, if the display is not working, check the power to the user control and display board. If the user control and display board has power, but it isn’t working, replace it.

Cause 2

Timer

The timer is frequently misdiagnosed—before replacing the timer, first check all of the more commonly defective parts. To determine if the timer is defective, consult your washer’s wiring diagram and use a multimeter to test the timer for continuity.

Cause 3

Line Fuse

The line fuse blows if the washer circuits are overloaded. If the line fuse blows, the washer won’t start. To determine if the line fuse is at fault, use a multimeter to test it for continuity. If the fuse does not have continuity, replace it. In addition, you should investigate and resolve the problem that caused the fuse to blow. Check for shorted out components such as the wires, motor, or drain pump. If you don’t resolve the underlying issue, the new fuse will blow too.
