Why does my dryer not turn off?

Checking for a stuck start button

Sometimes the start button can become stuck in and not shut off when the cycle is finished. To check if this is the case, press the start button and hold it down while the dryer is running. If the dryer continues running and doesn’t shut off when the button is released, then the button is stuck. To fix this, gently poke the button with a pencil to release it.

Once you have access to the control board, locate the motor relay and test it with a multimeter. If the motor relay is defective, it will need to be replaced. You can find replacement parts for your dryer at most home improvement or appliance stores or order them online.

Another possible cause of a dryer that won’t shut off is a stuck start button. In this case, the dryer may continue to run even after the button is released. To check if this is the problem, try pressing the start button repeatedly to see if it will dislodge. If the start button is stuck, it may need to be replaced.

If neither of these issues seems to be the problem, it’s possible that the anti-wrinkling feature is enabled. Some dryers have a setting that keeps the drum spinning intermittently to prevent wrinkles from setting in. If this setting is turned on, the dryer will continue to run even after the cycle is complete. To turn off this feature, consult your dryer’s manual for instructions.

In conclusion, if your dryer won’t shut off, it’s important to diagnose the problem quickly to prevent further damage or a potential safety hazard. By following these troubleshooting steps, you should be able to identify the cause of the issue and take the necessary steps to get your dryer back up and running again.

Replacing the motor relay on the control board

If you find that the motor relay is defective, you’ll need the right tools and replacement parts to fix it. For this job, you’ll need a soldering iron and the exact same model of replacement motor relay as the one being replaced. Once you’ve accessed the control board, unplug the electrical connectors, remove the defective motor relay – this may be difficult as the relay is soldered into the circuit board – insert the new one and solder it in.

Expert tip

If you’re not confident about your ability to replace the control board or motor relay on your dryer, it’s best to seek the assistance of a professional technician. Attempting to do the job yourself, without the necessary knowledge or experience, can be dangerous and may result in further damage to your appliance or even injury to yourself.

A qualified technician will have the necessary tools and expertise to diagnose and repair your dryer’s electrical components quickly and safely. They will be familiar with the specific requirements of your dryer’s make and model and will be able to identify and resolve any issues efficiently.

In addition to ensuring that the repair is done safely and effectively, hiring a professional technician to perform the job can save you time and money in the long run. Attempting to repair your dryer yourself may result in costly mistakes or the need for additional repairs.

Ultimately, when it comes to repairing your dryer’s electrical components, it’s best to leave the job to the experts. A qualified technician can get your appliance up and running again quickly and safely, giving you peace of mind and allowing you to get back to your normal routine.

Checking the lint trap

A clogged lint trap can also cause the dryer to not shut off. To check, open the lint trap and clean out any accumulated lint. Be sure to check for any small objects that may be blocked behind the lint filter. Also check the vent pipe for any build-up of lint or debris that could be impeding air flow.

Testing the push-to-start switch

If the push-to-start switch is worn or damaged, the dryer may not shut off. To test the switch, unplug the wires from each side and use a multimeter to test the connections. If the meter reads a continuous circuit, the switch is faulty and needs to be replaced.

Inspecting the drum glides

The drum glides can become worn over time and cause the dryer to stick in the on position. To inspect them, remove the front access panel and check the glides for any damage or wear and tear. If they’re worn, replace with new ones of the same size.

Checking the door sensor

On many newer dryers, the door sensor helps to ensure the dryer will shut off when the door is opened. To check the sensor, disconnect power and remove the door switch. Use a multimeter to test the continuity of the switch. If there is no continuity, the door switch is faulty and needs to be replaced.

After replacing parts

Once the defective parts have been replaced and the dryer is reassembled, it should be tested before being put back into service. Plug the dryer into a power outlet and turn it on. Allow the dryer to go through a complete cycle and make sure it will shut off at the end. If there are any further issues, further troubleshooting may be required.

Inspecting the heating element

In some cases, the heating element can fail and cause the dryer to not shut off. To check the heater element, disconnect power, remove the access panel and inspect the element for any signs of burning. If the element is burned, it should be replaced.

Checking the thermal fuse

In some models, a defective thermal fuse can cause the dryer to not shut off. To test the fuse, disconnect power and locate the fuse on the back panel of the dryer. Use a multimeter to test the continuity of the fuse. If the meter reads zero, the fuse is broken and needs to be replaced.

Testing the control board

The control board can be tested by plugging the dryer into a power outlet and powering it on. Then press and hold the start button for about five seconds to reset the control board. If the dryer turns on, it’s an indication that the control board is working correctly.

Testing the push button

The push button is one of the most important components in the dryer, and if it’s damaged, it could be causing the dryer to not shut off. To test the push button, connect the meter probes to each side of the switch terminals and test the continuity. If the meter reads zero, the switch is faulty and needs to be replaced.

Keeping your dryer In good working order

Regular maintenance and cleaning are important for keeping your dryer running in optimal condition. At least every 6 months, inspect and clean the lint trap, inspect the drum glides, check the heating element, and test the start button and door sensor. Doing this will help keep your dryer functioning at its best.

Troubleshooting a dryer that won’t shut off can be a daunting task, but the most common causes are a faulty motor relay on the control board, an enabled anti-wrinkling feature, a stuck start button, and a clogged lint trap.

Proper maintenance is key to keeping your dryer running in optimal condition and regular cleaning and inspection of parts such as the lint trap, drum glides, and heating element will help ensure your dryer continues to shut off without any issues. If the problems persist, or you don’t feel confident doing the work yourself, it’s best to get professional help.
