Whirlpool Dryer Won't Start But Has Power

Quick answer

If your Whirlpool dryer has power but won't start, check the door switch, thermal fuse, and motor. Ensure the dryer is properly grounded and the power cord is secure. If these don't resolve the issue, replace the thermal fuse or motor.

Confirm the symptom

• Dryer has power (lights, display working)
• Dryer won't start or run when turned on
• No unusual noises or smells when attempting to start
• Power cord is plugged in and outlet is working

Tools and prep

• Screwdrivers (flathead and Phillips)
• Multimeter for testing electrical components
• Work gloves and safety glasses
• Owner's manual for reference
• Replacement parts if needed (thermal fuse, motor, etc.)
• Dryer unplugged from power source

Step-by-step troubleshooting

1. Check the Dryer Door Switch
   Do: Open the dryer door and locate the door switch. Press the switch with a screwdriver while the door is open.
   Observe: If the dryer starts when the switch is pressed, the door switch is faulty.
   Means: A faulty door switch prevents the dryer from starting when the door is closed.
   Next: Replace the door switch.
2. Test the Thermal Fuse
   Do: Locate the thermal fuse (usually on the exhaust duct) and test it with a multimeter.
   Observe: If the multimeter shows no continuity, the thermal fuse is blown.
   Means: A blown thermal fuse is a common cause of a dryer not starting due to overheating.
   Next: Replace the thermal fuse.
3. Inspect the Power Cord and Outlet
   Do: Check the power cord for damage and ensure it is securely plugged into a working outlet.
   Observe: If the cord is damaged or the outlet isn't working, the dryer won't start.
   Means: A damaged power cord or faulty outlet can prevent the dryer from receiving power.
   Next: Replace the power cord or use a different outlet.
4. Check the Dryer's Grounding
   Do: Ensure the dryer is properly grounded by checking the grounding wire and connection.
   Observe: If the grounding is poor, the dryer may not start for safety reasons.
   Means: Improper grounding can cause the dryer to malfunction or not start.
   Next: Fix the grounding connection.
5. Test the Dryer Motor
   Do: Use a multimeter to test the dryer motor for continuity.
   Observe: If there's no continuity, the motor is faulty.
   Means: A faulty motor can prevent the dryer from starting.
   Next: Replace the dryer motor.
6. Check the Start Switch or Capacitor
   Do: Inspect the start switch or capacitor for visible damage or wear.
   Observe: If the start switch or capacitor is damaged, the dryer won't start.
   Means: A faulty start switch or capacitor can prevent the motor from starting.
   Next: Replace the start switch or capacitor.

Common causes

Parts matching

Replace the faulty part with a compatible Whirlpool dryer part. Ensure the part matches your dryer model by checking the model number on the dryer's data plate.

• Door switch: Look for the correct door switch model number for your Whirlpool dryer.
• Thermal fuse: Ensure the thermal fuse is compatible with your dryer model.
• Power cord: Use a power cord that matches the dryer's voltage and plug type.
• Grounding wire: Use a grounding wire that is the correct length and gauge for your dryer.
• Dryer motor: Verify the motor matches your dryer's specifications and model number.
• Start switch or capacitor: Ensure the start switch or capacitor is compatible with your dryer model.

Consult the owner's manual or contact Whirlpool customer support for the correct part numbers and compatibility information.

When to call a professional

• If you're not comfortable working with electrical components.
• If the dryer still won't start after replacing all the common parts.
• If the issue involves complex electrical or mechanical repairs.
• If the dryer is under warranty and you don't want to risk voiding it by attempting repairs yourself.
