How to replace a water softener timer

How to replace a water softener timer

This DIY repair guide explains how to replace the timer in a water softener. The timer controls the water softening and regeneration cycles, and lets you program the settings of the water softener. If there's power to the water softener but the display is blank, or if the control panel won't work when you touch a button, replace the timer with the manufacturer-approved water softener part.

Use this procedure to replace the timer in Kenmore, GE and Whirlpool water softeners.
