Short answer: Replacing the thermal fuse on a Samsung dryer is crucial for safety and dryer efficiency. Follow the guide to ensure correct replacement and address underlying issues.

Replacing the thermal fuse on a Samsung dryer is an essential skill for maintaining the safety and functionality of your appliance. This critical safety component acts as a guardian against overheating and potential fire hazards. Understanding how to replace it correctly is not only a valuable maintenance task but also a means to ensure your dryer operates reliably. In this guide, I will walk you through the step-by-step process, enabling you to confidently replace the thermal fuse and address any underlying issues that may have led to its failure, ensuring your Samsung dryer’s continued efficiency and safety.

What Does Your Dryer Thermal Fuse Do?

The thermal fuse in a dryer is a critical safety component that serves the following key functions:

  1. Overheating Protection: Its primary purpose is to protect the dryer and your home from the risk of overheating. When the dryer’s internal temperature rises to an unsafe level due to various reasons, such as a malfunctioning thermostat, blocked ventilation, or a defective heating element, the thermal fuse activates.

  1. Fire Prevention: By interrupting the electrical circuit to the dryer’s heating element or gas burner, the thermal fuse prevents excessive heat from building up, reducing the risk of a fire hazard. This is a crucial safety feature to protect both your appliance and your home.
  2. Appliance Safety: The thermal fuse ensures the safe operation of the dryer by shutting it down if it detects temperatures beyond its rated threshold. This helps prevent damage to the dryer’s components and potential harm to users.
  3. Indicator of Problems: When the thermal fuse blows, it is often an indication of an underlying issue in the dryer, such as a clogged vent, a malfunctioning thermostat, or a defective heating element. This prompts the user to address the problem before using the dryer again.

Where Is Thermal Fuse On Samsung Dryer?

The thermal fuse in a Samsung dryer is typically located on the back of the dryer’s blower housing or exhaust duct. It is a safety device designed to prevent the dryer from overheating and potentially causing a fire. The specific location of the thermal fuse can vary slightly depending on the model of your Samsung dryer, but it is generally situated in the vicinity of the dryer’s heating element.

How To Replace The Thermal Fuse On The Samsung Dryer?

To replace the thermal fuse on your Samsung dryer, follow these steps:

  1. Identify the Components: You’ll need to work with two components: the Samsung dryer thermistor (DC32) and the DC47 thermal fuse. These parts may sound similar, but they have distinct functions.
  2. Access the Components: Begin by removing the back panel of the dryer. Look for a screw that secures the pipe, and remove it to pull out the pipe.
  3. Locate the Parts: On the back of the blower, you’ll find the thermistor and thermal fuse. The thermal fuse is white, and the thermistor is blue. Both are held in place by Phillips screws.
  4. Remove the Old Components: Unscrew the Phillips screws to detach the old thermistor and thermal fuse. Carefully take out the old parts.
  5. Install the New Components: Replace the old components with the new ones and secure them with screws. Make sure to reconnect the wires to their respective locations.
  6. Check Component Resistance: Before finalizing the installation, it’s advisable to measure the resistance of the new components to ensure they are in good working condition. The thermal fuse should read around 0.06 ohms.
  7. Secure the Thermistor: For the thermistor, there’s a slot where it fits in. Once it’s correctly positioned, secure it with a screw at the bottom. Ensure that the connectors are clean and free of lint to prevent any issues.
  8. Finalize the Installation: Double-check all connections and make sure everything is securely in place.

What Happens When The Thermal Fuse Blows?

When the thermal fuse in a dryer blows, it triggers several consequences:

  1. Dryer Stops Working: The most immediate effect is that the dryer stops operating. The blown thermal fuse interrupts the electrical circuit to the heating element or gas burner, preventing it from producing heat.
  2. No Heat: Since the thermal fuse cuts off power to the heating component, the dryer will continue to operate in terms of tumbling the clothes, but it won’t generate any heat. This results in clothes remaining damp and not drying properly.
  3. Indicator of a Problem: The blown thermal fuse serves as an indicator that there is an issue within the dryer. It’s a safety mechanism designed to alert users that the dryer has overheated or experienced a malfunction.
  4. Safety Measure: Importantly, the blown thermal fuse acts as a safety measure. It prevents the dryer from running at excessively high temperatures, reducing the risk of fire or damage to the appliance and home.
  5. Necessities Repair: To restore the dryer to normal operation, the blown thermal fuse must be replaced. However, it’s crucial to identify and address the root cause of the overheating or malfunction that led to the fuse blowing in the first place. Simply replacing the thermal fuse without addressing the underlying problem may result in a recurring issue.


Can Samsung dryer turn on if the thermal fuse is blown?

No, a Samsung dryer will not turn on if the thermal fuse is blown. The thermal fuse is a safety device designed to interrupt the electrical circuit and prevent the dryer from operating if it detects that the dryer’s temperature has risen to an unsafe level, usually due to overheating.

How do I clean the lint filter in my Samsung dryer?

To clean the lint filter, simply pull it out from the dryer and remove the lint collected on the screen. Regular cleaning helps maintain dryer efficiency and safety.

Why is my Samsung dryer not heating up?

Several factors can cause this issue, such as a blown thermal fuse, a faulty heating element, or issues with the thermostat. It’s recommended to check these components or consult a technician for diagnosis and repair.

How can I troubleshoot a noisy Samsung dryer?

Noises in a dryer can result from loose objects, worn drum rollers, or a malfunctioning blower wheel. Carefully inspect and clean the interior of the dryer and its components. If the issue persists, consider professional repair.

Can I use dryer sheets in my Samsung dryer?

Yes, you can use dryer sheets in your Samsung dryer. However, it’s essential to use them as directed on the dryer sheet packaging to avoid any potential issues with the dryer’s sensors or lint filter.


Replacing the thermal fuse on a Samsung dryer is a crucial maintenance task that ensures the appliance’s safe and efficient operation. This safety component plays a vital role in preventing overheating and fire hazards by interrupting power to the heating element when needed. By following the step-by-step instructions provided, users can successfully replace the thermal fuse, ensuring their dryer functions reliably while prioritizing safety. It’s essential to diagnose and address any underlying issues that may have caused the fuse to blow in the first place to prevent future occurrences and maintain the longevity of the appliance.
