- No power to the timer display (for digital models)
- Timer clicks but doesn't change settings
Tools and prep
- Unplug the dryer from the power source
- Screwdrivers (flathead and Phillips)
- Multimeter for testing electrical continuity
- Replacement timer assembly (if needed)
- Worklight or flashlight
- Rubber gloves for safety
Step-by-step troubleshooting
