Timer knob rotates freely on the shaft without turning the timer — D-shaped bore is cracked or stripped, preventing cycle time from being set.
Unable to choose Timed Dry, Air Fluff, or Wrinkle Release because the knob slips or falls off the control panel during use.
Visible cracks in the plastic body or split D-shaft opening caused by wear, repeated twisting, or heat exposure over years of use.
Knob detached completely from the timer shaft, leaving the metal D-shaft exposed and the dryer inoperable without a grip point.




💡 Pro Tip: How to Know Your Timer Knob Needs Replacing
Your part is likely the culprit if you notice any of the following:
⚠️ Knob spins freely on the shaft without engaging the timer — cycle time cannot be set
⚠️ Visible crack or split in the D-shaped center opening, causing the knob to slip
⚠️ Knob fell off the control panel or is loose and wobbles during use
⚠️ Unable to select Air Fluff, Timed Dry, or Wrinkle Release cycles because knob won't stay in position
🛠 Quick Test: Remove the knob and inspect the D-shaped inner bore. If the flat edge is rounded off or the plastic is cracked, replace the knob. If the metal timer shaft itself is hard to turn even without the knob, the timer motor may also need attention — but start with the knob first as it's a $10 fix vs. a $40+ timer.
