GE Dryer Not Advancing or Stopping? Timer WW02F00566 – Fix Dryer Cycle Control Failure Fast

A failed dryer timer is the most common reason a GE electric dryer won't advance through cycles, runs continuously, or stops before clothes are dry. In most GE and Samsung-built dryers, this is caused by a worn-out mechanical timer assembly. When it fails, the dryer either gets stuck in one cycle position, runs indefinitely without shutting off, or won't start a timed cycle at all — leaving laundry wet and the appliance unreliable. ⚡ Common failure point in GE-built dryers after extended use. Part WW02F00566 is the genuine OEM replacement timer that restores precise cycle control and automatic shutoff immediately.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Dryer powers on and heats normally
• ✔ Motor runs — drum spins when cycle is started
• ✔ Electrical supply confirmed OK — no tripped breaker
• ✔ Thermal fuse confirmed good (no continuity break)
• ✔ ONLY problem is the timer dial not advancing, dryer not stopping, or timed cycles not working

🔧 Common Symptoms

• Dryer runs continuously and won't shut off automatically — most common, what customers Google
• Timer dial doesn't advance during the cycle
• Dryer stops too early before clothes are dry
• Dryer won't start when timer is set
• Timer knob spins freely with no resistance — internal gear stripped
• Dryer works on some timer positions but not others

✔ If these symptoms match, this is the most likely failed component in the system.

✔ In most cases, replacing this dryer timer restores normal timed cycle operation immediately.

⚙️ Installation

Skill Level: EASY — 20–30 minutes. Unplug the dryer before starting. The timer is located behind the control panel — remove the end caps and lift the panel to access it. Disconnect the wiring harness from the old timer (photograph connections first), remove the mounting screws, and swap in the new WW02F00566. Reconnect the harness, reassemble the panel, and test all timer positions before pushing the dryer back into place.
