Dryer Won’t Stop

The parts or conditions listed below if dryer won’t stop are ordered from most to least likely to occur.

Commercial dryer won’t stop

Cause 1 – Airflow Problem

When the dryer vent becomes clogged, it will prevent air from flowing through the dryer, increasing the amount of time required for drying. The dryer venting system should be cleaned at least annual in order to guarantee the ideal dryer performance. This the first probability if dryer won’t stop .

Cause 2 – Blower Wheel

The blower wheel is propelled by the drive motor, drawing air into the drum of the dryer and pushes it out through the vent. Oftentimes, lint, socks, and other small items can escape the lint filter and get trapped in the blower wheel. Additionally, the blower wheel sleeve can wear out sometimes, causing the fan wheel to wobble on the motor shaft. If the blower wheel becomes clogged or is otherwise defective, then it will cause the dryer to take too long. In order to determine whether the blower wheel is working well, remove the dryer vent and assess the degree of air flow. To determine whether the blower wheel is properly working, you must remove the dryer vent and assess the degree air flow. If there is not much air flow, make certain that nothing is obstructing the blower wheel. If the blower wheel is not being obstructed by an object, try to turn it by hand. If the blower wheel wobbles, then you must replace it. This a high probability if dryer won’t stop .

Cause 3 – Gas Valve Solenoid

Oftentimes, gas-based dryers will have two or sometimes more gas valve solenoids. These solenoids are responsible for opening the gas valve and permitting gas flow to the burner. However, it can sometimes fail to do so while in the drying cycle, which causes the dryer to take a long time. To determine whether one or more of the gas solenoids have stopped working, check the igniter. If it turns on but does not ignite the gas, then that means that the gas valve solenoid is defective. If one or more of the gas valve coils are defective, we recommend replacing them as a set.

Cause 4 – Heating Element

The heating element is responsible for heating up the air prior to entering the dryer drum. If the heating element is not working, then the dryer may not heat up. To determine if the heating element is faulty, use a multimeter to test its continuity. If the heating element does not have continuity, then you must replace it.

Cause 5 – Heating Element Assembly

The assembly of the heating element heats the air as it passes through. If some other part of the assembly is defective, then the dryer may fail to heat up. If the dryer does not heat up, then it will take a long time to dry the clothes. To determine whether the heating element is faulty, test its continuity with a multimeter. If the heating element does not have continuity, then replace it.

Cause 6 – Lint Filter

The lint filter sometimes becomes clogged with material. Dry leaves and even fabric softener can leave clog up the lint filter, thereby reducing airflow. If the lint filter is clogged, then clean it.

Cause 7 – Humidity Sensor

The humidity sensor is responsible for monitoring the moisture of the clothes, signaling the control board when the clothes are dry. If it is not working as it should be, then it could signal that the clothes are still wet, keeping the dryer running although the clothes are dry. However, this is uncommon. Before replacing the humidity sensor, you should first check all the most commonly defective parts. If you have determined that all other components are working correctly, then you have to replace the humidity sensor.

Cause 8 – Cycling Thermostat

The cycling thermostat regulates the air temperature by turning the heat on and off. If the cycle thermostat is not working, then the dryer will not heat up. This is uncommon, though. Before replacing the cycling thermostat, check all the most commonly defective parts. If you have determined that the other components are working as they should be, test the thermostat with a multimeter to verify continuity. If the thermostat does not have continuity, then replace it.

Cause 9 – High Limit Thermostat

The high limit thermostat is responsible for controlling the temperature of the dryer and shutting off the burner in case the dryer overheats. If the high limit thermostat does not work properly, you can turn off the burner even if the dryer does not overheat. However, this is also uncommon. Before replacing the high limit thermostat, check all the most commonly defective parts. If you have determined that all other components are working correctly, test the thermostat with a multimeter to verify its continuity. If the thermostat does not have continuity, then replace it.

Cause 10 – Thermistor

Some dryer models have a thermistor. The control board uses the thermistor to control the temperature of the dryer and turn the heating on and off. If the thermistor is not working as it should be, then it may not activate the ignition cycle, causing the clothes not to dry properly.

Cause 11 – Timer

Mechanical timers usually come with a motor similar a clock. This motor is responsible for rotating the timer down to the off position on the control board. If the motor stops working for whatever reason, the timer will not move and the dryer won’t stop. This the last probability if dryer won’t stop .

These are the possible causes if the dryer won’t stop

  1. I found this article really useful because of the detailed, yet straight-to-the-point, information it provides and the way this information is organized. If you dare to go about the repair of your dryer by yourself, It will save you time since the conditions are ordered from the most to the least likely to occur.
    If you happen to be inexperienced like me, the ideal plan would be to start checking the dryer following the order provided. But I believe it is not easy to open a machine like this and put hands on sensitive parts that could be damaged as a result of one’s intervention. So, my recommendation would be to read the article first, go through all the possible causes for the problem, and then make up your mind on what part to start with.
    As I am a very obsessed person, I’m sure that, should my dryer have this problem, it would have no relation with the airflow since I regularly check all pipes and vents for clogs. Another cause I would set aside from the start is the gas valve solenoid since my dryer is electric. What about using a multimeter to test the continuity of the heating element? I don’t see myself doing so! I don´t even know what a multimeter is. I would find myself picking up the phone and calling someone for assistance. On the other hand, the heating element is something that should be paid attention to as it sounds like critical to the dryer.
    Replacing parts such as the humidity sensor or the cycling thermostat by yourself instead of calling a specialist can save you money provided that the part you are replacing is actually faulty. If not, again, it is better and cheaper to call a specialist.
    Some years ago, the timer of my washing machine broke down. As the article explains, the timer is similar to a mechanical clock responsible for controlling the operations of the machine. At that time, I managed to replace it by myself following an article like this one. The experience was very positive and I think, faced with a similar situation with my dryer, I would fix it by myself.
    As a conclusion, if you are inexperienced but willing to save some dollars, this article will be of great help as far as you read it carefully and follow the instructions. If you are acquainted with this kind of machines and used to repairing them, it will provide you with more than useful technical information and the way to detect the cause of the problem to be able to solve it.

  2. There are some conditions or problems that make that a dryer don’t stop. The most common ones are:
    Airflow Problem: If the venting system is not clean it prevents to the air flow freely, increasing drying time. For that reason dryer won’t stop when you want.
    Blower Wheel: If this wheel is wobbling or there is not much air flow, maybe something is obstructing the blower wheel. You must clean by hand to remove any items that can escape the lint filter or change blower wheel.
    Mechanical timers usually come with a motor similar a clock. This motor is responsible for rotating the timer down to the off position on the control board. If the motor stops working, the timer will not move and the dryer won’t stop.

  3. The bad functioning of your dryer when it won’t stop is associated to several reasons that cause the delay in the ending of the drying process. The most common causes, from top to bottom, may be related to an air flow problem (produced by the clogged of the dryer vent); a defective or obstructed blower wheel; or a defective solenoid (if you have a gas dryer), all of which may provoke the dryer to take too long to dry the clothes.
    Some other causes for your dryer bad functioning are the loss of continuity of either the heating element or the heating element assembly, which in this case should be replaced. If everything exposed above is defectless and you have already clean the dryer lint filter, it’s time to check the working of the humidity sensor. If there is no problem with it, you should then test the cycling thermostat and the high limit thermostat to also verify their continuity and replace the needed element.
    As less common problems to occur we may face the inappropriate functioning of the thermistor (causing the clothes not to dry properly); and the stopping of the motor connected to the timer, causing the last won’t move and consequently the dryer won’t stop.
    In any case, if someday you have to deal with this kind of issue when using your dryer, you could just follow the instructions and information given to determine where the problem is, and find the best solution to solve it.

  4. Your dryer could be having troubles stopping for various reasons.
    It could be happening because the dryer machine has’nt been cleaned in the last months causing that your dryer won’t stop.
    Also, the solenoids could be the cause. If these have stopped working while you do your laundry, can cause the dryer to delay and take a longer time than it usually does.
    The rotating clock could be the problem too, if it stopped working could be causing the bad functioning of your machine.
    On the other hand, the humidity sensor could be messed up and it could be indicating you that your clothes are still wet, even though they are perfectly dried.

    In all the previous cases (and some other less commons) the best choice is to call your mechanic and have him/her come over to your place to get your dryer machine fixed.

  5. There are some reasons that could be causing your dryer machine to stop.
    The most frequent ones are:
    -The bad functioning of the humidity sensor, that could have indicated you that your clothes were wet, even though they may been perfectly dried.
    -The rotative clock.
    -The lack of proper air flow could also cayse that your dryer won’t stop.

    Summing up, these are some of the main reasons, but there is more. The most recommended thing to do if you see that your dryer is damaged is to call your mechanic and have him/her come to your place and get your dryer machine fixed, so you can continue doing your laundry peacefully.

  6. The typical problems associated with the dryer malfunction resulting in the dryer not stopping can be separated in three branches. First, the Airflow Issues, these are the most common causes for a prolonged cycle. If the air does not flow properly into the drum and out of the dryer the capabilities of the machine are drastically reduced and the amount of time of the drying process increases. The usual problems are associated with the obstruction of the vent, blower wheel wearing or trapping and the clogging of the lint filter. The second branch comprises the Heating Failures, this is a crucial step of the dryer cycle. The heater gets the air to the proper temperature for its circulation and the drying of the clothes. If the system fails at this stage the air temperature will not be enough to remove the humidity from the fabric so the dryer would not stop. Some critical failures are associated with the malfunction of the valve gas solenoids, the heating element and the assembly of the heating element. These problems are less common than the Airflow Issues but still quite relevant, in general involve the replacement of the damaged parts. The final category encircles all the Sensor Breakdowns. The sensor systems are responsible for regulating the temperature and airflow through the dryer. In case of malfunctioning of these systems the dryer can exhibit a variety of behaviors causing the machine to not stop. The humidity and temperature sensors are typical examples, in some other cases the timer may get damaged as well. These are the least probable difficulties of the list although some of the more complex since they involve the replacement of a very sensitive element.

  7. There are several causes why the dryer won’t stop like: airflow problems and issues with the blower wheel, gas valve solenoids, heating element or its assembly, humidity sensor, cycling thermostat, high limit thermostat, thermistor or timer. The most uncommon causes are the cycling thermostat, the high limit thermostat and timer malfunctions, timer issues are the most uncommon causes.
    The previous article explains why each cause might happen and what to do, like
    Cleaning needed because of clogged objects:Dryer Vent,
    Check with a multimeter before replacing:Heating Element, Humidity Sensor, Cycling Thermostat, High Limit Thermostat, Thermistor(not all models have it)
    And it also explains what the components job is.

  8. There are several conditions that can make your dryer won´t stop. Some causes are related to the passage of time or to the breakage of some piece due to mishandling. The problem may also be related to weather conditions.

    Some of the most frequent causes that cause that your dryer won´t stop, are related to problems with the ventilation system, elements that block the whreel blower. Other causes are problems in the gas valve solenoid, malfunction of the heating element and defective assembly of the heating element.

    They can also prevent your machine from stopping, an obstruction of the lint filter, defective parts in the humidity sensor, problems with the Cycling Thermostat or with the High Limit Thermostat, thermistor or timer malfunction.

    For these reasons, if your machine has a problem, check it and then contact an expert for repair.
