How to Fix Samsung Dryer Not Heating

Have you noticed your Samsung dryer is not heating up? The majority of the cases are caused by a burnt heating element, and other causes may be a blown thermal cut-off fuse, cycling thermostat, or a failed control board heater relay. Your Samsung dryer not heating up could also be caused by an improper power supply. In this article, you will learn amazing ways to fix Samsung dryer, not heating.

Make sure you have cleaned the vent lines and lint filters of your Samsung dryer as a clogged vent line will make your Samsung dryer not heating properly. Ensure you check all parts of the dryer to be sure what the problem is. Double-check on thermostats, thermal cut-off fuse, wiring, voltage, and vent line.

Experiencing this problem is very frustrating for many people if it is summer or winter, a dryer is always an essential electronic at home. Is your Samsung developing some drying issues? Below are specific steps you should take to verify where the problem may be coming from.

Common Issues to Fix When Samsung Dryer Is Not Heating

The following are the top issues causing Samsung dryer not to heat. Follow through the guidelines carefully to effectively and efficiently fix your dryer problems:

Check Heated Short-Circuit to Fix Samsung Dryer Not Heating

The first part of your dryer to check is the thermal fuse. The main reason for this component is to help protect the dryer from overheating.

To Inspect the heated short-circuit:

  • Ensure you switch off the dryer.
  • Disconnect the top and side panels.
  •  Find the thermal fuse on the blower housing or at the heat source of the dryer.
  • Once you find the thermal fuse continuity, use a multimeter to check.
  • Ensure the fuse is closed when checking for continuity. It’s important to note that it has a continuous electrical path through it. When there is no continuity in the fuse, this implies it needs a replacement, as it has blown.
  • After the replacement of the fuse, make sure the exhaust vent is unblocked, and if you discover it has been blocked, unblock it so the fuse doesn’t blow again.Fix samsung dryer not heating

Check the Gas Valve Solenoid and Igniter

Is your dryer gas-powered? If yes, the next components to check are the gas valve solenoid and the igniter (but if your dryer is electric, then you don’t need to check the heating element). Irrespective of the specific model of your Samsung dryer, it should have two or more gas valve solenoid coils, that helps to open the gas valve ports to allow easy flow of gas to the burner assembly. The igniter then powers on the gas so that your dryer can heat. If any of these components fail, your dryer won’t be able to heat.

To inspect them:

  •  You need to check if the igniter is working to check if the gas valve solenoid is faulty or not. To achieve this, check if the igniter is glowing and ignites the gas or not without igniting the gas.
  • Check it for continuity if the igniter is not glowing at all. If the igniter has no continuity, then it needs a replacement.
  • Check if the gas does not ignite but the igniter is glowing, then the whole set of gas valve coils need a replacement.
  • Have you replaced either the gas valve solenoid coils or the igniter? Then be sure the problem has been fixed. Sometimes the two will need replacement. 

Inspect The Fire Sensor to Fix Samsung Dryer Not Heating

One other component of a gas dryer that might be causing your dryer not to heat is a faulty flame sensor. A flame sensor determines how hot the dryer is from the flame, and once it stops working, your dryer won’t be able to heat.

Inspecting the fire sensor is easy; you just need to:

  • Ensure the dryer is properly switched off.
  • Find the flame sensor (disconnect the top and side panels)
  • To check the sensor for continuity, use a multimeter (make sure it is at room temperature when checking).
  • If the sensor has continuity, then it is working perfectly, and you can continue checking the next component. But, if the test shows no continuity, it will need a replacement.

The Heating Element

The heating element of electric dryers functions properly when air gets heated up before it goes up into the dryer drum. When it doesn’t work correctly, your Samsung dryer won’t heat.

To inspect the element:

  • Make sure your dryer is switched off.
  • Disconnect the top and side panels to find the heating element.
  • Ensure you use a multimeter to check for continuity. If there is no continuity, it needs a replacement. If it has continuity, then it’s working fine, and you can continue to check the next component.

Inspect the Incoming Power

If there is a problem with the incoming power to your dryer, then your Samsung dryer will not heat up. Two legs of 120 volts AC (250 volts in total) are required for electric dryers to operate optimally. At times, one of the fuses can trip, meaning the dryer might still run but not heat.

To inspect the fuses:

  • Find your household fuse box.
  • Ensure to find the correct fuses that make the dryer come up.
  • To ensure it has the correct voltage, test each fuse with a multimeter, and if not, you’ll need a replacement.

High-Level Thermostat

Was the issue caused by the power supply? If No, then the next thing to check is the high-limit thermostat. The thermostat monitors the temperature in your dryer and closes the burner off when your dryer overheats. When it becomes faulty, your dryer may shut down when it shouldn’t.

 Inspect the high-limit thermostat:

  • Make sure you switch it off
  • Find the high-limit thermostat.
  • Check the thermostat with a multimeter to see if it has continuity.
  • If the test shows no continuity, then it needs a replacement; if it does have continuity, it is working perfectly, and you can continue with checking the next component.

The Cycling Thermostat

Almost all dryers also have a cycling thermostat that works to cycle the heat on and off to regulate the air temperature in the dryer. Your dryer won’t heat when it becomes faulty.

To inspect the cycling thermostat:

  • Ensure the power is still off.
  • Find the cycling thermostat.
  • Test the thermostat with a multimeter to see if it has continuity.
  • Is the test showing no continuity? Then it needs to be replaced; if it does have continuity, it is working perfectly, and you can move on to inspecting the next component.

The Timer

If you are yet to find the cause of your dryer not the heating problem, the next component you can check is the timer. Timers in dryers don’t usually break down, but it’s possible. You can fix the Samsung dryer, not the heating.

If you’ve inspected all of the other components above, then check the timer:

  • Make sure the dryer is switched off.
  • Find the timer.
  • Use your multimeter to check the timer for continuity.
  • If it has continuity, then it is working correctly, and if not, it needs a replacement.

Replace the Main Control Board

If you are yet to find a solution to the cause of the problem, your final option is to replace the main control board. Basically, the “brain” of your dryer is the main control board, and when it is faulty, your dryer will stop working perfectly. Control boards are very difficult to test, so if you’ve tried everything else, consider getting a replacement for the control board and then check if the problem has been solved. However, depending on how old your dryer is, it might be a better option to just get a new one.

If you still can’t find a solution to your Samsung dryer not heating up even after doing the above steps, it may be time to consult with a professional. They will assist with a quick and easy fix. I hope this article was helpful and insightful.
