Short answer: If your Samsung dryer won’t start or run, check the door latch, power supply, and error codes. Clean the lint filter and exhaust vent, and consider professional assistance if needed.

A malfunctioning dryer can be a frustrating and inconvenient issue to deal with, especially when you rely on it to keep your clothes clean and dry. If your Samsung dryer refuses to start or run, you’re not alone – this problem can occur for a variety of reasons, ranging from simple issues to more complex electrical or mechanical problems. In this guide, I will explore some common troubleshooting steps to help you diagnose and potentially resolve the issue, allowing you to get your Samsung dryer back up and running efficiently. Before calling a technician or considering a replacement, it’s worth investigating these potential solutions to save time and money.

Troubleshooting Why Your Samsung Dryer Won’t Start

  1. No Power To The Dryer: If your Samsung dryer won’t start, the first thing to check is whether it’s receiving power. Ensure that the power cord is properly plugged into the electrical outlet, and confirm that the outlet is functional by testing it with another appliance. Sometimes, a tripped circuit breaker or a blown fuse can cause a lack of power to the dryer.
  2. Dryer Door Not Latched Shut: Modern dryers typically have a safety feature that prevents them from starting if the door isn’t securely latched. Make sure the dryer door is fully closed and latched properly. If the door isn’t closed correctly, the dryer won’t start.
  3. Samsung Dryer Thermal Fuse Failure: The thermal fuse is a safety device designed to prevent overheating in the dryer. If it blows due to excessive heat, the dryer won’t start. Check the thermal fuse for continuity with a multimeter. If it’s blown, replace it.
  4. Defective Samsung Dryer Start Switch: The start switch is what initiates the dryer’s operation when you press it. If it’s defective or damaged, the dryer won’t start. Test the start switch for continuity with a multimeter and replace it if necessary.
  5. Samsung Dryer Control Board: The control board is like the brain of your dryer, responsible for managing its various functions. If it’s malfunctioning or has a burnt-out component, it can prevent the dryer from starting. Inspect the control board for any visible damage, and if needed, replace it.
  6. Object Stuck in Blower Wheel: Sometimes, foreign objects like lint, small articles of clothing, or debris can get stuck in the blower wheel. This can obstruct the dryer’s airflow and cause it not to start. Check the blower wheel for any obstructions and remove them.
  7. Samsung Dryer Drive Motor: The drive motor powers the drum’s rotation. If the motor is faulty, the dryer won’t start. Test the motor for continuity and replace it if it’s not functioning properly.
  8. Samsung Dryer Timer Issue: The timer controls the duration of each drying cycle. If it’s defective, it can prevent the dryer from advancing through the cycles or starting at all. Check the timer for continuity and replace it if needed.

How To Fix Samsung Dryer Not Running?

Use Different Dryer Settings:

  • Start by ensuring you’ve selected the desired settings on the dryer’s control panel. Make sure the cycle, temperature, and timer settings are appropriate for your laundry load.
  • If the dryer still won’t start, try selecting different settings to see if it responds.

Check the Door Lock and Switch:

  • Inspect the dryer door to ensure it’s fully closed and latched securely. Most dryers have a safety mechanism that prevents them from running with an open door.
  • Look for any visible damage or misalignment of the door latch.
  • If you find any issues with the door or latch, address them by repairing or replacing the faulty parts.

Check Dryer’s Circuit Breaker:

  • Locate your home’s circuit breaker panel and check if the circuit breaker that supplies power to the dryer has tripped.
  • If the circuit breaker has tripped, reset it by switching it off and then back on.
  • Try starting the dryer again to see if it works.

Check Samsung Dryer Thermal Fuse:

Check Error Codes: Samsung dryers often have error code displays that can help diagnose specific issues. Refer to your dryer’s manual to interpret the error codes. If you see an error code displayed, follow the recommended steps in the manual to address the issue.

Check Child Lock Mode Is Turned Off:

Some Samsung dryers have a child lock feature that can prevent the dryer from starting. Refer to your user manual to learn how to deactivate the child lock mode.

Control Board Issues:

  • If none of the above steps resolve the issue, it’s possible that the control board has a problem.
  • Inspect the control board for any visible damage or burnt components.
  • If you have experience with electronics, you can attempt to diagnose and repair the control board, but it’s recommended to consult a professional technician for this type of repair.

Preventative Maintenance Tips

Clean the Lint Filter After Every Load: Remove and clean the lint filter or lint screen after each drying cycle. Accumulated lint can reduce dryer efficiency and pose a fire hazard.

Regularly Clean the Dryer Vent:

  • Disconnect the dryer from the power source and detach the vent hose from the back of the dryer.
  • Use a vent brush or vacuum attachment to remove lint and debris from the vent hose and the vent opening in the wall.
  • A clogged dryer vent can reduce airflow and efficiency, so cleaning it regularly is essential.

Inspect and Clean the Exhaust Duct:

Clean the Drum and Interior:

  • Wipe down the interior of the dryer, including the drum, with a damp cloth to remove any residue or fabric softener buildup.
  • Inspect the drum for any rough spots or snags that could damage clothing. If you find any, consider sanding them smooth.

Check the Door Seal:

  • Examine the door seal for any signs of wear, damage, or gaps. A damaged seal can result in heat loss and reduced drying efficiency.
  • Replace the door seal if necessary.

Inspect the Power Cord and Plug:

  • Periodically check the power cord and plug for any signs of wear, fraying, or damage.
  • Ensure the plug fits securely into the outlet and that there are no exposed wires.

Level the Dryer: Check that the dryer is level and stable. An unlevel dryer can cause vibrations and noise during operation. Adjust the leveling legs as needed.

Keep the Area Around the Dryer Clear: Make sure the space around the dryer is free from clutter, lint, and dust. Adequate ventilation helps prevent overheating.

Inspect and Clean the Lint Chute: Remove the lint chute (located inside the door) and clean it thoroughly to prevent lint buildup.

Schedule Professional Maintenance: Consider scheduling annual or periodic maintenance by a qualified technician. They can perform a more comprehensive inspection and address any potential issues.


Why is my Samsung dryer not running even though the control panel lights up?
