This 3-position switch (Part #8191600) is a replacement power control for the Kenmore 3306. The switch selects among its three settings to control power to the machine and its functions. A worn switch can cause intermittent power, refuse to turn on, or fail to shut off, and it may feel loose or need repeated toggling to catch. Those are signs the internal contacts have failed. A fresh switch restores reliable, positive control.
