How to Fix a Samsung Dryer Not Heating: A Comprehensive Guide

Samsung dryers are renowned for their efficiency and reliability. However, like all appliances, they can sometimes experience issues. One common problem is the dryer not heating, leaving you with wet clothes and frustration. Fortunately, there are various ways to fix this issue. In this blog post, we will discuss nine possible causes and solutions for a Samsung dryer not heating and answer five frequently asked questions related to this topic. Let’s dive in!

Thermal Fuse

A blown thermal fuse is a common cause of a Samsung dryer not heating. The thermal fuse is a safety device to prevent the dryer from overheating. It is usually located on the blower housing and will blow if the temperature inside the dryer cabinet gets too high, cutting off the power to the heating element.


  • Locate the thermal fuse on the blower housing.
  • Test the fuse using a multimeter for continuity.
  • Replace the blown thermal fuse if necessary.

Gas Valve Solenoid and Igniter

In a gas-powered Samsung dryer, the gas valve solenoid coils play a crucial role in heating. These coils control the gas flow to the burner and heater assembly together. If faulty, the gas valve ports will not open, and the dryer will not heat. Additionally, the igniter is responsible for igniting the gas in the burner assembly. The dryer will only produce heat if the igniter is working correctly.


  • Test the gas valve solenoid coils and igniter using a multimeter.
  • Replace the defective gas valve solenoid coils or igniter if necessary.

Flame Sensor

The flame sensor is a crucial component in a gas dryer. It detects the presence of a flame in the burner assembly and ensures that the gas valve remains open to maintain the heat source. A faulty flame sensor will prevent the dryer drum from heating properly.


  • Locate the flame sensor near the burner assembly.
  • Test the flame sensor using a multimeter for continuity.
  • Replace the faulty flame sensor if necessary.

Heating Element

The heating element is responsible for generating heat in electric Samsung dryers. If the element is defective, the dryer will not function properly without heat.


  • Locate the heating element in the electric dryer that’s cabinet.
  • Test the new heating element using a multimeter for continuity.
  • Replace the defective front heating system element with a new one if necessary.

Check the Incoming Power

An incoming power problem can cause a Samsung dryer not to heat. Ensure the power supply to the dryer is functioning correctly by checking the circuit breaker or fuse box.


  • Check the circuit breaker or fuse box for blown fuses or tripped circuit breakers.
  • Replace the blown fuse or reset the circuit breaker if necessary.
  • Consult an electrician for further assistance if you still experience issues.

High-Limit Thermostat

The high-limit thermostat is a safety device that monitors the hot air and temperature inside the dryer. If the air temperature becomes too high, the high-limit thermostat will shut off the heat source to prevent damage. If this component fails, the dryer may not heat.


  • Locate the high-limit thermostat near the heating element or burner assembly.
  • Test the high-limit thermostat using a multimeter for continuity.
  • Replace the faulty high-limit thermostat if necessary.

Cycling Thermostat

The cycling thermostat is responsible for the heat cycle contact regulating the dryer temperature during automatic cycles. A malfunctioning cycling thermostat can cause the dryer not to heat.


  • Locate the cycling thermostat in the dryer’s cabinet.
  • Test the cycling thermostat using a multimeter for continuity.
  • Replace the defective cycling thermostat if necessary.


The timer is responsible for controlling the heat cycle in your Samsung dryer. If the timer is not functioning correctly, the dryer may not heat, or the dirty dryer may heat inconsistently.


  • Locate the timer in the control panel of the dryer.
  • Test the timer’s contacts using a multimeter for continuity.
  • Replace the faulty timer if necessary.

Main Control Board

The main control board on electric dryers manages all of the dryer’s functions, including heating. If the control board is faulty, it can cause the dryer not to heat.


  • Check for any visible damage on the main control board.
  • If you suspect a faulty control board, it is recommended to consult a professional technician for proper diagnosis and replacement.


A Samsung dryer not heating can be caused by various issues, such as a few gas valve coils, a blown thermal fuse, defective gas valve solenoid coils, or a faulty heating element. By following the solutions provided in this guide, you can troubleshoot and fix the problem. Always unplug the dryer and turn off the gas supply before attempting any repairs.


Why is my Samsung dryer running but not heating?

If your Samsung dryer is running but not heating, it could be due to a defective heating element or other issues such as a malfunctioning thermostat, a blown thermal fuse, or problems with the power supply. Identifying the specific issue is essential for resolving the problem and getting your dryer functioning properly again.

Why is my dryer running but not heating?

A dryer running but not heating can be caused by various factors, including a faulty heating element, an incorrect power supply, a damaged thermal fuse, or a broken thermostat. It’s crucial to examine these components and repair or replace them as needed to fix the problem.

How do I reset my Samsung dryer heating element?

Samsung dryers do not have a reset button specifically for the heating element. However, you can try resetting the dryer by unplugging it from the power source for a few minutes and then plugging it back in. This may help clear any minor electronic glitches. If your dryer still isn’t heating, you may need to test the heating element for continuity, which indicates a continuous electrical path. If the heating element is found to be defective, it will need to be replaced.

How do I know if my heating element is bad on my Samsung dryer?

To determine if the heating element is bad on your Samsung dryer, you can perform a continuity test using a multimeter. First, make sure to unplug the dryer from the power source. Then, access the heating element by removing the dryer’s back panel. Disconnect the wires connected to the heating element and set the multimeter to the lowest resistance setting (usually denoted by the Ω symbol). Place the multimeter probes on the heating element’s terminals, and check for continuity. If the multimeter shows a reading close to zero or displays “OL” (open loop), it indicates that the heating element is defective and needs to be replaced.

How often should I clean the lint filter in my Samsung dryer?

It is recommended to clean the lint filter after every load to ensure proper airflow and prevent lint screen overheating.

Can a blocked vent cause my Samsung dryer not to heat?

Yes, a blocked vent can cause the dryer to overheat, potentially blowing the thermal fuse and causing the dryer not to heat. Regularly check and clean your dryer vent system to avoid this issue.

What is the average lifespan of a Samsung dryer?

A Samsung dryer typically lasts 10 to 13 years with proper maintenance.

Can I replace the heating element in my Samsung dryer myself?

If you are comfortable with basic electrical repairs and have the necessary tools, you can replace the heating element yourself. However, if you need more clarification, it is recommended to consult a professional technician.

How can I prevent my Samsung dryer from overheating?

To prevent overheating, ensure proper airflow by regularly cleaning the lint filter and air vent system, avoiding overloading the dryer with wet clothes, and maintaining a clean dryer cabinet. Additionally, check for any faulty components, such as the thermal fuse or thermostats, and replace them if necessary.
