1. Power Supply Challenges

When troubleshooting startup issues with your Samsung dryer, start by checking the power supply. Here’s how:

  • Ensure the dryer is properly plugged into a functional electrical outlet.
  • Check the circuit breaker or fuse box for any tripped breakers or blown fuses.
  • Replace blown fuses and reset tripped breakers if necessary.
  • Additionally, consider professional assistance to inspect your home’s wiring for any underlying electrical problems.


  • Adequate power supply is essential for resolving startup problems.
  • Addressing basic power flow issues can help eliminate common startup issues before further troubleshooting.

2. Door Switch Malfunction

A malfunctioning door switch is a common reason why a Samsung dryer may fail to start. Here’s what you need to know:

  • The door switch ensures the dryer operates only when the door is properly closed.
  • Physical damage or misalignment over time can lead to the switch malfunctioning.
  • Look for signs of damage like loose wires or bent prongs; replace the switch assembly if necessary.
  • Use a multimeter to test the switch’s functionality by measuring electrical resistance.
  • Refer to a DIY repair guide for your model to safely access and test the door switch.
  • Always disconnect the dryer from its power source before attempting any repairs for safety.

3. Thermal Fuse Failure

When a Samsung dryer fails to start, a common cause is a thermal fuse failure. Here’s how to troubleshoot and fix it:

  • Start by unplugging the dryer for safety.
  • Locate the thermal fuse, usually near the blower wheel housing.
  • Check for damage like discoloration or broken wire connections.
  • Test the fuse’s continuity with a multimeter; infinite resistance means it’s blown.

To replace it:

  1. Order a compatible replacement part from an authorized supplier.
  2. Disconnect power and access the old fuse.
  3. Note wire positions, remove the old fuse, and install the new one.
  4. Reassemble the dryer and restore power.

By addressing this issue promptly, you’ll ensure safe operation of your Samsung dryer.

4. Start Switch Problems

If your Samsung dryer is not starting, the problem might lie with the start switch. Here’s what to do:

  • Begin by unplugging the dryer and emptying it of any items.
  • Use a multimeter set to continuity mode to test the terminals on the start switch.
  • If there’s no continuity when pressing the switch, it’s likely faulty and needs replacing.
  • Before any repairs, ensure the dryer is disconnected from power.
  • Consult the user manual or a DIY repair guide for your specific model to replace the start switch.
  • Use appropriate tools like wire cutters and screwdrivers for the task.

By following these steps, you can troubleshoot and fix start switch problems in your Samsung dryer, restoring its functionality safely.

5. Defective Timer

A defective timer might be why your Samsung dryer won’t start. Here’s what to do:

  • Check for signs of wear or loose connections on the timer.
  • If visually inspecting doesn’t reveal issues, use a multimeter to test for continuity.
  • Follow safety guidelines and consult the user manual when working with electrical parts.
  • If the timer is faulty, get a compatible replacement specified for your Samsung dryer model.
  • Disconnect power before replacing the timer to avoid accidents.
  • Replacing the timer should resolve the startup issue and restore functionality to your dryer.

6. Damaged Belt

If your Samsung dryer won’t start, a damaged belt might be the culprit. Here’s how to diagnose and fix the issue:

Diagnose the Problem:

  • Unplug the dryer and open the door to locate the belt.
  • Manually rotate the drum; if you feel resistance or hear unusual noises, the belt may be damaged.
  • Look for visible signs of wear or breakage on the belt.

Replace the Belt:

  • Disconnect power and access the rear panel of the dryer.
  • Remove screws or clips to access the belt area.
  • Carefully remove the old belt and replace it with a new one of the same size and specifications.
  • Use specialized tools like a screwdriver, nut driver, or socket wrench set for the job.
  • If you’re not comfortable with DIY repairs, seek professional assistance for safe installation.

By addressing a damaged belt promptly, you can restore your Samsung dryer’s functionality and ensure safe operation.

7. Motor Issues

Motor problems can often be the reason why a Samsung dryer fails to start. Here’s what you need to know:

  • Faulty Start Switch: The start switch, located on the control panel, activates the motor when pressed. Damage or wear can cause it to fail, preventing the dryer from starting.
  • Troubleshooting: Check for loose connections or visible damage on the start switch. Cleaning or replacing it may solve the issue.
  • Broken Belt: The belt connects the motor to the drum for rotation. Wear or damage over time can cause it to break, resulting in a humming sound but no drum movement when starting the dryer.
  • Fixing the Belt: Open the dryer cabinet and replace the broken belt with a new one using appropriate tools.


  • Careful Troubleshooting: Addressing motor issues requires careful troubleshooting techniques and knowledge of your specific model.

8. Electronic Control Board Failure

A common frustration with Samsung dryers is electronic control board failure, which can prevent the dryer from starting. Here’s what you need to know:

Causes of Failure:

  • Power surges or electrical fluctuations can damage the circuitry.
  • Excessive heat from malfunctioning parts like thermal fuse or motor issues can degrade the control board.

Troubleshooting Steps:

  • Check for blown fuses or tripped circuit breakers in your home’s electrical panel.
  • Reset breakers and replace blown fuses if necessary.
  • If power issues are ruled out, consult a professional or refer to a DIY repair guide specific to your model for safe replacement.

When your Samsung dryer won’t start, electronic control board failure could be to blame. Take proactive steps with maintenance and repairs to keep your dryer functioning smoothly.

9. Flashing Error Codes

Dealing with error codes flashing on your Samsung dryer can be frustrating, but understanding them can help you troubleshoot effectively:

  • “dE” Error Code: This indicates a door switch malfunction. Check for physical damage or wear on the door switch mechanism and replace if necessary.
  • “SE” Error Code: This points to a problem with the start switch. Ensure the start switch is securely connected and not damaged, replacing it if needed.


  • Error codes are initial indicators for troubleshooting.
  • Consult your dryer’s manual or seek professional help if unsure.
  • Promptly addressing issues like door switch or start switch problems can restore your dryer’s functionality.

Tips To Prevent a Samsung Dryer From Failing to Start

Preventing startup issues with your Samsung dryer is crucial to save time and avoid frustration. Here’s how:

  • Regular Maintenance: Clean the lint filter after every use to prevent airflow restriction and overheating. Inspect and clean the venting system every few months to remove blockages.
  • Caution with Loading: Avoid overloading the dryer to prevent strain on the motor and belt. Distribute the load evenly and ensure proper balance, especially with large items.
  • Inspect Key Components: Regularly check for loose or frayed wires around the door and start switch connections. Promptly replace any damaged components to avoid future problems.
  • Error Code Awareness: Take note of error codes displayed by your dryer. Consult the user manual or search online for explanations and solutions to address specific issues.

By following these preventive measures, performing regular maintenance tasks, inspecting key components, and staying informed about error codes, you can significantly reduce the likelihood of startup issues with your Samsung dryer.
