Dryer Overheats

The part or condition enumerated Dryer Overheats is ordered from the most to least like to occur. Check or test each item, beginning with those on top of the page.

Commercial Dryer Overheats

Cause 1 – Heating Element

The heating element heats up air as it travels through the drum of the dryer. If the heating element short-circuits, it generates heat incessantly, whether or not the dryer has reached the desired temperature, causing the dryer to overheat. In order to determine whether the heating element has failed, you must test the continuity of each terminal in the case with a multimeter. If the heating element has continuity with the case, then it has short-circuited. If the heating element is short-circuited, then you must replace it. This is the highest probability if the Dryer Overheats

Cause 2 – Heating Element Assembly

The heating element heats up air as it travels by the element. If the element is short-circuited, it generates heat incessantly, whether or not the dryer has reached the desired temperature, causing the dryer to overheat. In order to determine if the heating element has failed, you must test the continuity of the heating element with a multimeter. If the element does not have continuity, then you must replace it. Then, test the continuity from the terminals to the case. If the heating element has continuity with the case, then it has short-circuited. If the heating element is short-circuited, you must replace it.

Cause 3 – Airflow Problem

If the ventilation of the dryer is even partially obstructed, it can cause airflow within the dryer to become restricted. If airflow is restricted, then the dryer will take a long time. The ventilation system of a dryer should be cleaned at least annually to ensure the ideal performance.

Cause 4 – Cycling Thermostat

The cycling thermostat activates the heat to maintain the temperature of the air. If the thermostat is faulty, it can keep the heat on for a long time, causing the dryer to overheat. However, this is uncommon. Before replacing the cycling thermostat, check all of the more commonly faulty parts. If all the other components work correctly, check the thermostat with a multimeter to determine its continuity. If the thermostat does not have continuity, then you must replace it.

Cause 5 – Felt Seal

Most of dryers have a felt seal in the front and back part of the drum to retain heat by keeping it from escaping the drum. If the seal is damaged or absent, the heat will not be able to leave the dryer drum, causing the dryer to overheat. Check the seal of the drum to ensure that it is properly trapping in heat. However, this is uncommon. Before replacing the felt seal, check all of the more commonly faulty parts. If all other components work correctly, then you must replace the felt seal.

Cause 6 – Blower Wheel

The blower wheel is propelled by the drive motor, drawing air into the drum of the dryer. Oftentimes, lint, socks, and small items escape the lint filter and become trapped in the blower wheel. The sleeve of the blower wheel can also become damaged, causing the wheel of the fan to wobble on the axis of the motor. If the blower wheel is obstructed or faulty, it can cause the dryer to overheat. To determine if the blower wheel is functioning well, remove the dryer vent and evaluate the degree of air flow. If airflow is weak, check that there are not any other obstructions on the blower wheel. If no obstructions are present, then rotate the wheel of the fan with the hand. If the blower’s wheel wobbles as it rotates, then you must replace it.This is the lower probability if the Dryer Overheats

3 thoughts on “Dryer Overheats

  1. A dryer overheats when it generates more hot air than necessary. Dryer overheating may be caused by several reasons.

    To start with, if the dryer overheats, the heating element, which is the component that heats up air inside the drum, is highly likely to be out of order. A short-circuit in this element results in a constant flow of hot air inside the dryer drum, regardless of dryer necessary temperature. The heating element should be the first component to be tested in order to determine whether it works or not, due to the fact that this is the most likely reason for overheating. Should the heaing element fail to operate effectively, it must be replaced.

    Not only may overheating be caused by a failure in the heating element, but also it could result from an airflow problem. Even though this problem is not as common as the heating element failure, it should be taken into account. Should the dryer ventilation be blocked, the dryer will have to work harder, leading to overheating. Proper cleaning will prevent the dryer ventilation from being blocked.

    Another factor that could give rise to overheating is a failure in the cycling thermostat. The cycling thermostat is the dryer component that regulates the heat inside the drum. In the event that the cycling thermostat fails to work properly, air will be heated up without stop, leading up to dryer overheating.

    Apart from that, overheating might arise from damage in the felt seal. The felt seal is a component fitted around the front and the back part of the dryer drum that keeps the heat inside the drum. Provided that the felt seal is damaged, hot air will escape from the drum and the dryer will warm up air without stop in order to reach the desired temperature inside the drum, which results in dryer overheating.

    Finally, blower wheel obstruction could be another reason for overheating. Despite the fact that a blower wheel obstruction is extremely unlikely to happen, it could be a reason for overheating. The blower wheel is the component that draws air into the dryer drum. In the event that it is blocked or damaged, it will produce a weak flow of air, making the dryer to work harder and, consequently, to overheat.

    All in all, if the dryer oveheats, the first component to be tested should be the heating element. Whether the heating element works properly, the dryer ventilation should be tested. Provided that both of the components mentioned before operate normally, then, the cycling thermostat could be the problem. Should all these components work perfectly, then, the felt seal may be damaged or the blower wheel may be blocked.

     
  2. Why does your Dryer Machine overheat?

    The Dryer Machine may overheat due to many causes, the most likely cause of overheating is a short-circuit of the heating element, if this happens you must replace it. Another cause of overheating could be an airflow problem. If the ventilation of the dryer is partially obstructed it can cause airflow within the dryer to become restricted. When thermostat is faulty, it can cause an overheating. If the thermostat does not have continuity must be replaced, this is uncommon. It is important to check the seal, that is located in the front and back part of the drum, if the seal is damaged or absent this will cause an overheating, and should be replaced. This is also an uncommon cause. The obstruction or the fault of the blower wheel can be a problem too, this is the lower probability if the dryer overheats.

     
  3. Causes of overheated dryer

    There’s a few causes that determinates when a washing machine is overheating. You must check on the heating element assembly, airflow element, cycling thermostat, felt seal and the blower wheel and be able to recognize the functions of each one of them.

    First, the heating element heats up air as it travels through the drum of the dryer. To know if has failed, you must test the continuity of each terminal in the case with a multimeter. Then, the other way around. If the heating element has continuity with the case, then it has short-circuited. Then, check the heating element assembly. If the element is short-circuited, it generates heat incessantly, whether or not the dryer has reached the desired temperature

    The Airflow element. If the ventilation of the dryer is even partially obstructed, it can cause airflow within the dryer to become restricted. The cycling thermostat. It activates the heat to maintain the temperature of the air. First, check all of the more commonly faulty parts. If all the other components work correctly, check the thermostat with a multimeter to determine its continuity.

    The felt seal. Retains heat by keeping it from escaping the drum. Check all of the more commonly faulty parts first. Then, If all other components work correctly, then you must replace the felt seal. The blower wheel. Is propelled by the drive motor, drawing air into the drum of the dryer. If the blower wheel is obstructed or faulty, it can cause the dryer to overheat. To determine if its working properly, remove the dryer vent and evaluate the degree of air flow.
