Dryer Has Power But Won't Start

Quick answer

First, check if the door is properly closed. Ensure the start button is pressed. If the dryer still won't start, inspect the thermal fuse and door switch. If these are functional, examine the control board.

Confirm the symptom

• Dryer is plugged in and receiving power.
• No error codes or lights on the control panel.
• Dryer drum does not spin when start button is pressed.
• Dryer makes no sounds when attempting to start.
• Dryer is not heating or tumbling.

Tools and prep

• Screwdriver (Phillips and flathead)
• Multimeter
• Owner's manual
• Safety gloves
• Unplug the dryer from the power source.
• Ensure the dryer is cool before starting repairs.

Step-by-step troubleshooting

1. Check the Door Switch
   Do: Locate the door switch, usually near the door frame.
   Observe: Press the switch with your finger to see if it clicks.
   Means: If it doesn't click, it may be faulty.
   Next: Test the switch with a multimeter for continuity.
2. Inspect the Thermal Fuse
   Do: Find the thermal fuse, often located on the blower housing or exhaust duct.
   Observe: Look for any signs of burning or damage.
   Means: A damaged fuse needs replacement.
   Next: Test the fuse with a multimeter for continuity.
3. Test the Start Switch
   Do: Locate the start switch on the control panel.
   Observe: Check for any visible damage or wear.
   Means: A faulty switch will not start the dryer.
   Next: Test the switch with a multimeter for continuity.
4. Examine the Control Board
   Do: Access the control board, usually behind the control panel.
   Observe: Look for any burnt or damaged components.
   Means: A faulty control board may need replacement.
   Next: Test the board with a multimeter for continuity.
5. Check the Drive Motor
   Do: Locate the drive motor, usually at the base of the dryer.
   Observe: Listen for any unusual noises when trying to start.
   Means: A faulty motor may not start the dryer.
   Next: Test the motor with a multimeter for continuity.
6. Inspect the Belt
   Do: Remove the dryer cabinet to access the belt.
   Observe: Check for any signs of wear, damage, or breakage.
   Means: A broken or worn belt will prevent the dryer from starting.
   Next: Replace the belt if necessary.
7. Verify the Timer
   Do: Locate the timer, usually on the control panel.
   Observe: Check for any visible damage or wear.
   Means: A faulty timer may prevent the dryer from starting.
   Next: Test the timer with a multimeter for continuity.
8. Check the Thermal Cut-Off Switch
   Do: Find the thermal cut-off switch, often on the heating element.
   Observe: Look for any signs of burning or damage.
   Means: A faulty switch needs replacement.
   Next: Test the switch with a multimeter for continuity.

Common causes

Parts matching

Replacing faulty parts can often resolve the issue of a dryer having power but not starting.

• Door Switch: Ensures the dryer starts only when the door is closed.
• Thermal Fuse: Protects the dryer from overheating.
• Start Switch: Initiates the drying cycle.
• Control Board: Manages the dryer's functions and settings.
• Drive Motor: Powers the dryer's drum.
• Drive Belt: Connects the motor to the drum.
• Timer: Controls the drying cycle duration.

Always ensure you have the correct replacement part for your dryer model.

When to call a professional

• If the dryer still won't start after troubleshooting.
• If you are not comfortable working with electrical components.
• If you encounter any major damage or unusual issues.
• If the dryer is under warranty, contact the manufacturer.
• If you need help identifying the correct replacement part.
• If you suspect a gas leak (for gas dryers).
