A cracked or slipping timer knob cannot engage the D-shaft, preventing the timer from being set to any cycle position and stopping the dryer from starting entirely.
When the knob's internal grip fails, it spins freely without rotating the timer mechanism, causing the dryer to run indefinitely or stop prematurely mid-cycle.
Cracks in the plastic collar or a worn D-shaft bore allow the knob to spin without engaging the timer shaft, making it impossible to select or change drying time settings.
Physical cracking of the plastic knob body — a common failure mode on this part — prevents proper gripping and timer control. Replacement is the only repair option.




💡 Pro Tip: How to Diagnose a Failed WE1M652 Timer Knob
Your part is likely the culprit if you notice any of the following:
⚠️ Knob spins freely on the shaft without engaging the timer mechanism
⚠️ Visible cracks, splits, or chips in the plastic body of the knob
⚠️ Dryer will not start because the timer cannot be set to a cycle position
⚠️ Timer does not advance or stops mid-cycle due to knob slipping on the D-shaft
🔍 Quick check: Try to feel resistance when turning the knob. If you can spin it without the timer clicking forward, the knob's D-shaft grip has failed. Always replace the knob before condemning the timer itself — the WE4M533 timer is considerably more expensive. If the knob keeps cracking repeatedly, the timer shaft may be binding; consider replacing the timer (WE4M533) and knob together.
