Why Dryer Timers Fail
Mechanical Wear and Tear
Mechanical dryer timers eventually wear from years of use. Internal electrical contacts and gears can fail after thousands of cycles, causing issues with dryer operation.
Common symptoms of failure include:
❌ Timer won't advance
❌ Dryer won't start
❌ Dryer gets stuck on one cycle
❌ Dryer shuts off incorrectly
❌ Knob feels loose or spins freely
Replacing the timer restores normal cycle operation when the rest of the dryer is functioning properly.

Frequently Asked Questions
1. Why won't my GE dryer timer advance?
Mechanical dryer timers eventually wear from years of use. Internal electrical contacts and gears can fail after thousands of cycles, which prevents the timer from advancing normally.
2. What happens when a dryer timer breaks?
Common symptoms include the timer failing to advance, the dryer refusing to start, the machine getting stuck on one cycle, or the dryer shutting off incorrectly.
3. Why does my dryer knob spin freely?
If the knob feels loose or spins freely, the internal plastic assembly inside the control knob has likely fractured, or the timer shaft itself has broken, requiring replacement.
