The control knob rotates without engaging cycle positions — the inner D-shaft grip has stripped or cracked, preventing proper encoder contact.
Dryer or washer fails to start because the damaged knob cannot properly select or hold a cycle position on the control panel.
The knob body is visibly cracked, chipped, or the center insert has separated, making it impossible to operate the appliance normally.
The appliance runs an unintended cycle because the worn knob slips past detent positions, failing to lock onto the correct program setting.
💡 Pro Tip: Is Your Control Knob the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Knob spins freely without clicking through cycle positions
⚠️ Dryer or washer won't start — knob can't engage a cycle
⚠️ Knob is visibly cracked, chipped, or the center insert has broken off the shaft
⚠️ Settings change unexpectedly or the selected program doesn't match the indicator mark
Quick test: With the appliance unplugged, pull the knob straight off and inspect the D-shaped plastic insert. If the flat face is stripped or rounded, the encoder grip has failed — replace the knob only. If the metal shaft itself is damaged, the control board assembly may also need attention.
