Common Symptoms

  • Cracked or broken knob
  • Knob spins without changing the cycle
  • Knob will not stay attached to the timer stem
  • Washer controls do not respond because the knob cannot engage the timer stem

Check Before Replacing

  • With the appliance disconnected from power, inspect the knob for cracks, a stripped hub, or damaged retaining features.
  • Check whether the knob’s internal opening positively engages the timer stem rather than spinning freely.
  • Verify that the timer stem and knob align correctly and that the knob remains seated when gently operated.
  • If a replacement knob repeatedly comes loose, inspect the timer’s retaining mechanism and stem for damage before replacing the knob again.

Pro Tip

If the knob is intact but repeatedly falls off or spins freely, check the timer stem and retaining mechanism; the knob may not be the only damaged component.
