Dryer Not Heating Up? Most Common Causes And Fixes [2022]

The most common reason for your dryer not heating is a buildup of lint, which overheats the machine and damages an internal component. However, there may be a simpler solution in some cases. You can diagnose heating element for dryer and fix the problem of your dryer not heating with the help of this guide. 

Heating Element For Dryer: There has been a tripped circuit breaker

A tripped circuit breaker is an easy cause to check. A dryer with an electric motor has two 120-volt breakers, one for power and one for heating. Indeed, it is possible that the dryer is not heating because the heating circuit breaker has been tripped.

  1. Circuit breakers may have tripped on your electrical panel.
  2. It is important to reset circuit breakers as soon as possible if they have tripped.
  3. Fuse replacement is necessary if a fuse blows.

Due to a lack of gas, the dryer is not heating

One of the easiest reasons for a gas dryer not heating is a shortage of gas.

  1. In order for the gas to flow through the pipe, you will have to turn on the gas valve.
  2. It is necessary to connect the dryer to the gas pipes.
  3. If you have not paid your gas bill yet, you should do so as soon as possible.

There is a blockage in the lint trap

Even if your dryer has a lint screen, keep the screen clean after every cycle. Moreover, wash the lint screen in warm water and soap in the sink.

  1. Lint screen slots should be cleaned with a vacuum attachment when the screen is drying.
  2. An easier way to clean the lint screen is to unscrew and/or unclamp the panel surrounding it.
  3. The dryer should be disconnected from the power source and the gas should be turned off.
  4. If the dryer needs to be reassembled, put the lint screen back in place after cleaning, or move on to the next step.

Due to a malfunctioning timer, the dryer is not heating

It is possible that your dryer is not heating as a result of a faulty timer if it uses a mechanical timer. However, it is possible for a timer that does not advance to the next cycle to cause the heat to run until it becomes too hot, tripping the thermal fuse. Moreover, a faulty timer may prevent heat from being released in other models. The steps for checking and replacing the timer are as follows:

  1. The dryer should be unplugged from its power source.
  2. Turn off your gas dryer if you have one.
  3. Confirm the continuity of the small timer motor by finding it and testing it.
  4. You will need to replace either the timer or the motor if the continuity test fails.

An obstruction in the ventilation system

Do you suspect that your dryer is not heating up because of a ventilation blockage? The lint screens attached to the ventilation hose as well as the ventilation hose itself can sometimes become clogged with lint. Moreover, by checking the outside vent for constant, warm airflow, you can determine if the ventilation is working. The problem may be resolved by cleaning out this area after disconnecting the dryer hose. When moving your gas dryer, be careful to gain access to it.

  1. If your dryer is a gas dryer, turn off the gas and unplug it from the power source.
  2. Using a screwdriver or unclipper, remove the metal tape on the dryer’s ventilation hose.
  3. Access to the ventilation area may be improved by removing the panel surrounding it.
  4. If necessary, vacuum the area or use a ventilation cleaning kit.
  5. Reattach the dryer hose without scrunching it up to allow air to flow through.
  6. Finally, you may need to access this area again in order to resolve the next cause, if you removed any panels.

It seems that the dryer has accumulated a lot of lint

Unscrewing and/or unclipping dryer panels to get to the drum and motor may require you to clean more lint traps and ventilation areas.

  1. If your dryer is a gas dryer, turn off the gas and unplug it from the power source.
  2. Unclip and/or unscrew the front or back panel, depending on the model.
  3. To find the screws to the control panel or top of the dryer, it may be necessary to remove the top or top of the dryer.
  4. Make sure the lint is cleaned out.
  5. A photo can help you remember where any wires go if you need to detach them.
  6. The dryer may need to be reassembled or you may need to move on to the next problem.

An issue has arisen with the thermal fuse in the dryer, which is resulting in the dryer not heating.

There are several causes for a dryer not heating, but the most typical is a blown thermal fuse. However, your dryer is protected from catching fire by a thermal fuse. Additionally, on newer dryers, when a certain temperature is reached, a thermal fuse trips in order to prevent damage to the dryer. Indeed, it is possible for older dryer models to continue working, but without producing heat.

  1. You should turn off the gas in your dryer if it is a gas dryer and disconnect it from the power source.
  2. Thermal fuses can be found in the electrical panel.
  3. You will likely find the thermal fuse on the back of your dryer if your lint screen is on top.
  4. Unless your dryer is on the back, your lint screen will be located on the front.
  5. The dryer belt may be able to be loosened in order to remove the dryer drum.
  6. Check the continuity of the thermal fuse with a multimeter.
  7. New thermal fuses should be replaced with the old ones.
  8. It is recommended that the dryer be reassembled or that the cause of the problem be investigated.

You can prevent thermal fuses from blowing again by identifying the cause, and often lint buildup is responsible.

The dryer is not heating due to a problem with the element

The most common cause of dryer not heating is a faulty heating element. Moreover, as a result of wear and tear or lint blockages, coils in heating elements are often damaged.

  1. Turn off your gas dryer if you have one and unplug the dryer from its power source.
  2. The location of the heating element needs to be determined.
  3. The leads of the heating element are typically held in place by a metal frame that surrounds the heating coils.
  4. Using a multimeter, check that the heating element is connected.
  5. Multimeter tests indicate that the heating element needs to be replaced if it fails.
  6. A broken heating element can also be confirmed by finding breaks in the coils.
  7. Replacing the faulty heating element is the best solution.
  8. You can remember where the wires go by taking photos of them.
  9. Move on to the next possible cause if the heating element is not the issue.

Thermostat failure can result in dryer not heating

On most models, they are usually located near the heating element.

  1. Test the continuity of the thermostat leads with a multimeter.
  2. As the thermostat should be located next to the thermistor, the thermistor should also be located there.
  3. The thermistor should be tested again with a multimeter.
  4. Neither of these components should fail the multimeter test if the heating problem persists.
  5. To assist in replacing the part, take photos before removing it.

It is due to a faulty gas dryer flame sensor that the gas dryer is not heating

You may not be able to heat your gas dryer because the flame sensor is faulty. The air in a gas dryer is heated by a flame in order to dry your clothes. In the event of a faulty flame sensor, the flame will not ignite.

The flame sensor should be checked and replaced as follows:

  1. The flame sensor should be located. However, as a small black box, it is located under the dryer drum and attached to the flame igniter.
  2. A multimeter should be used to test the resistance of the circuit.
  3. Replacing the flame sensor if it is faulty is the best course of action.

After looking at the most common causes of a dryer not heating due to dryer heating element, you should be able to identify and resolve the issue as soon as possible.

Moreover, the dryer should be reassembled, ensuring that the power is connected and that the gas is turned on if necessary.
