Why is your Samsung Dryer Not Heating?

If you are experiencing the problem of your Samsung dryer not heating, a few potential causes may be responsible for this issue. This problem can cause a lot of inconveniences, especially when you need to dry clothes quickly.

1. Faulty Thermostat

A faulty thermostat can cause a Samsung dryer not to heat properly. The thermostat is responsible for regulating the temperature inside the dryer. If it’s not functioning correctly, it may not signal the heating element to turn on or off as needed. This can cause the dryer not to heat or overheat, leading to potential safety hazards.

2. Broken Heating Element

The heating element is crucial to the dryer, generating the heat required to dry clothes. If it’s broken, the dryer will not produce heat, and your clothes will remain wet.

3. Blown Thermal Fuse

The thermal fuse keeps the dryer from overheating and potentially causing a fire. If the dryer gets too hot, the thermal fuse will blow, cutting off power to the heating element and preventing it from functioning.

4. Clogged Venting System

A clogged or restricted venting system can cause a Samsung dryer not to heat up, even if all other components function correctly. The venting system is responsible for removing moisture and hot air from the dryer drum and venting it outside the house.

5. Gas Supply Issues

If you have a gas dryer, it relies on a steady supply of natural gas to generate heat. If the gas supply is interrupted or not reaching the dryer properly, it may prevent the dryer from heating up.

6. Control Board Failure

The control board sends signals to various dryer components, including the heating element, thermostat, and thermal fuse. If the control board is malfunctioning or faulty, it may prevent the dryer from heating up.

How to Fix Samsung Dryer Not Heating

If your Samsung dryer is not heating, various causes could be at play. This step-by-step guide on dryer repair will help you troubleshoot and resolve the issue effectively:

1. Check the Power Supply

Checking the power supply is essential in diagnosing a Samsung dryer that is not heating. Here’s how to do it:

  • Verify the power cord and outlet: Ensure the power cord is correctly plugged into the electrical outlet. If the plug is loose or damaged, the dryer may not receive the correct voltage required to heat.

If you believe the outlet is broken, you may test the voltage with a multimeter or put another item into the outlet to check if it works properly.

  • Inspect circuit breakers and fuses: Check your home’s electrical panel for any tripped circuit breakers or blown fuses. The dryer may have a dedicated circuit, so ensure it is in the “ON” position.

If a breaker has tripped, reset it by turning it to the “OFF” position and then back to the “ON” position. Replace blown fuses with replacement ones of the same amperage rating.

  • Assess the power cord: Inspect the power cord for any visible damage, such as fraying, cuts, or kinks. A damaged cord can compromise the power supply to the dryer. You may need to replace the power cord if you find any damage.
  • Test the terminal block: The terminal block is where the power cord connects to the dryer’s internal wiring. Unplug the dryer and remove the terminal.

2. Examine the Lint Filter

Over time, the filter can become clogged, restricting airflow and causing the dryer to overheat or not heat. Here’s how to examine and clean the lint filter:

  • Locate the lint filter: The lint filter is typically inside the dryer door or on the top. Consult your dryer’s user manual if you need help finding it.
  • Remove the lint filter: Carefully pull the lint filter out of its housing. Be gentle, as the filter may be delicate and prone to damage.
  • Inspect the lint filter: Inspect the lint filter for evident indications of wear, such as rips or holes. If you find any damage, you must replace the lint filter to ensure proper dryer performance.
  • Clean the lint filter: Remove any lint or debris from the filter by hand or using a soft brush. To remove lint from the surface of the filter, use a vacuum cleaner with a brush attachment.

For more thorough cleaning, rinse the filter under warm water and use a soft brush to remove any stubborn lint. Make sure the lint filter is completely dry before reinstalling it.

3. Inspect the Venting System

A blocked or restricted vent can lead to poor heating performance or even cause the dryer to overheat. Follow these steps to inspect and clean the venting system:

  • Disconnect the dryer vent hose: To reach the vent hose, unplug the dryer and move it away from the wall. Depending on your arrangement, disconnect the hose between the rear of the dryer and the wall vent by removing the clamp or the connector.
  • Inspect the vent hose: Look for apparent evidence of damage, such as rips, holes, or severe kinking, on the vent hose. Replace the hose if it’s damaged. Also, check for any lint or debris buildup inside the hose.

You can use a long, flexible brush or a vacuum with a hose attachment to clean the vent hose thoroughly.

  • Clean the dryer vent duct: The vent duct runs from the wall vent to the outside of your home. Use a vent-cleaning brush or a  vacuum with a long hose attachment to remove lint and debris from the duct.

You may need to access the duct from both ends (inside and outside) to clean it effectively. Be cautious while cleaning the duct, as you may encounter sharp edges or screws.

  • Check the external vent cover: Inspect the outer vent cover for any obstructions, such as lint buildup, debris, or animal nests. Make sure the vent flap opens and closes freely. Remove any obstacles and clean the vent cover as needed.
  • Reassemble the venting system: Once you have cleaned and inspected the venting system, reconnect the vent hose to the dryer and the wall vent. Secure the connections with clamps or tape, as appropriate. Put the dryer back into position and plug it in.
  • Test the dryer: Run a test cycle with damp clothes to see if the dryer heats appropriately. If the dryer is still not heating, you may need to investigate other potential causes, such as a faulty heating element or thermostat.

4. Test the Heating Element

The heating element generates heat inside the dryer; if it’s faulty, the dryer won’t heat properly. Here’s how to test the heating element:

  • Disconnect the power: Before you start, unplug the dryer from the power source to ensure your safety during the testing process.
  • Locate the heating element: Consult your dryer’s user manual to identify the heating element’s location, usually inside the rear panel or the bottom panel of the dryer. You might need a screwdriver to remove the panel and access the heating element.
  • Visual inspection: Check the heating element for any visible signs of damage, such as breaks or burns. If you find any damage, you must replace the heating element.
  • Continuity test: Use a multimeter to test the heating element for continuity. Set the multimeter to the lowest ohms reading possible (usually 200 ohms). Touch the multimeter probes to the heating element terminals.

A good heating element should register a reading between 10-50 ohms. If the multimeter shows no continuity or unusually high resistance, it indicates a faulty heating element that needs replacement.

  • Replace the heating element: If the heating element is faulty, you’ll need to purchase a new one compatible with your Samsung dryer model. Remove the old one from its mounting brackets and disconnect the wires to replace the heating element.
  • Reassemble the dryer: Reattach the panel removed earlier once the heating element has been tested or replaced. Plug the dryer back into the power source.
  • Test the dryer: Run a test cycle with damp clothes to see if the dryer heats appropriately.

5. Check the Thermostat

Most dryers have two types of thermostats: the high-limit thermostat and the cycling thermostat. Both play a role in regulating the temperature inside the dryer; if either is faulty, it can affect the dryer’s heating function.

  • Disconnect the power: Before you begin, unplug the dryer from the power source to ensure your safety during the testing process.
  • Locate the thermostats: They are typically located near the heating element, inside the rear or bottom panel of the dryer. You might need a screwdriver to remove the panel and access the thermostats.
  • Visual inspection: Check both thermostats for any visible signs of damage or burns. If you find any damage, replace the affected thermostat.
  • Replace the faulty thermostat(s): If you find a faulty thermostat, you’ll need to purchase a new one compatible with your Samsung dryer model. Remove the old one from its mounting brackets and disconnect the wires to replace the thermostat.
  • Reassemble the dryer: Reattach the panel removed earlier once the thermostats have been tested or replaced. Plug the dryer back into the power source.
  • Test the dryer: Run a test cycle with damp clothes to see if the dryer heats properly.
