Dryer Not Starting? Here's What to Check

A dryer that won’t start can be frustrating, especially when laundry piles up. Before calling for help, there are several things you can check to potentially solve the problem. This guide covers common reasons a dryer might not start and steps to troubleshoot effectively.

Common Reasons Your Dryer Isn’t Starting

Several factors can prevent a dryer from starting. Here are the most common causes:

1. Power Supply Issues
   The dryer needs a steady power source to operate. If the power supply is interrupted, it won’t start.

2. Faulty Door Switch
   The door switch prevents the dryer from running when the door is open. If the switch is broken, the dryer won’t start.

3. Blown Thermal Fuse
   The thermal fuse protects the dryer from overheating. If it blows, the dryer won’t function.

4. Malfunctioning Start Switch
   The start switch engages the motor to begin the cycle. If the switch fails, the dryer won’t respond.

5. Broken Drive Motor
   The motor drives the drum and blower wheel. A damaged motor can prevent the dryer from starting.

6. Control Board Problems
   The control board manages the dryer’s operations. If it malfunctions, the machine may not start.

7. Burnt Out Power Cord
   A damaged or burnt-out power cord can interrupt the dryer’s ability to start.

How to Troubleshoot

1. Check the Power Source

• Ensure the dryer is plugged into a working outlet.
• Test the outlet by plugging in another device.
• Check your home’s circuit breaker or fuse box for tripped breakers or blown fuses.

2. Inspect the Door Switch

• Open the dryer door and locate the door switch.
• Press the switch manually and listen for a clicking sound.
• If there’s no click, the switch may need replacement.

3. Test the Thermal Fuse

• Disconnect the dryer from the power source.
• Locate the thermal fuse (refer to your dryer’s manual for its location).
• Use a multimeter to check for continuity.
• Replace the fuse if it shows no continuity.

4. Examine the Start Switch

• Remove the control panel to access the start switch.
• Use a multimeter to test for continuity.
• If the switch is faulty, replace it.

5. Inspect the Drive Motor

• If the dryer hums but doesn’t start, the motor might be faulty.
• Consult a professional for further testing and replacement.

6. Check the Control Board

• Look for visible signs of damage, such as burn marks or loose connections.
• Replace the board if necessary.

7. Inspect the Power Cord

• Look for signs of damage, such as fraying or burn marks.
• Replace the cord if needed.
