Why Won't My Dryer Stop Drying?

If you feel like your dryer keeps spinning, or the cycle seems much longer than usual, there are several things you can check to fix your problem.

  • First check that your dryer is placed in a ventilated and clear place, neither too hot nor too cold. If the front of the unit isn’t clear, it won’t be able to draw in cool air well from the front and will take longer to dry your clothes.
  • Then make sure that you have chosen a drying program suitable for your laundry, which can affect the drying time. Check that you have not set a delayed start, for example, or that you have not launched a program for synthetic laundry to dry cotton clothes.
  • Finally, if the “release” function is activated on your dryer, the appliance will be able to stir the laundry for a very long time.

If your dryer continues to run despite these checks, you will need to test other elements.

  • Test the power outlet
  • Check laundry spin
  • Check door and duct filter
  • Check the dryer condenser
  • Test resistance
  • Check the drum bearing
  • Test the temperature probe
  • Test the electronic board.

In the world of home appliances, having a dryer that won’t stop drying can be as frustrating as one that won’t start. This issue can lead to several problems such as wasted energy, potential damage to clothes from overheating, and even safety concerns. If your dryer is continuously running, even after the clothes are dry, it might be due to several reasons. This article will explore the potential causes and their solutions.

Why Won't My Dryer Stop Drying?

Faulty Timer

The timer in a dryer is a crucial component that controls the length of the drying cycle. If your dryer doesn’t stop when it should, it’s possible that the timer is broken or malfunctioning.

Tip: If you suspect a faulty timer, you will most likely need to hire a professional to confirm the diagnosis and replace the part. Working with electrical components can be dangerous if not handled properly.

Malfunctioning Moisture Sensor

Many modern dryers have a moisture sensor, which detects how much moisture is left in the clothing. Once the clothes are adequately dry, the sensor signals the dryer to stop the cycle. If the sensor is dirty or broken, it might not be able to accurately detect moisture levels, causing the dryer to keep running.

Tip: Regularly clean the moisture sensor following your dryer’s manual to ensure it’s free from lint or residue. If cleaning doesn’t help, a professional might need to replace the sensor.

Problems with the Thermostat

A malfunctioning thermostat can cause the dryer to run continuously. The thermostat monitors the temperature inside the dryer and tells the dryer’s heating element when to heat up and when to cool down. If it’s not working correctly, it may not be able to correctly signal the end of the drying cycle.

Tip: A defective thermostat needs to be replaced by a professional, given the complexity of the task and the risk associated with mishandling.

Faulty Door Switch

The door switch signals the dryer when the door is closed and it’s safe to run. If the door switch is defective, it might send the wrong signals, causing the dryer to continue running even after the cycle should be complete.

Tip: If the door switch doesn’t click when you press it or if it’s visibly damaged, you’ll need a professional to replace it.

Defective Electronic Control Board

The electronic control board is like the brain of the dryer. It governs most of the functions, including turning the heat on and off, spinning the drum, and shutting off the machine when the clothes are dry. If the control board is faulty, it can send incorrect signals, leading to endless cycles.

Tip: An electronic control board is a complex and costly component. If you suspect that it might be the issue, consult a professional for a diagnosis and potential replacement.


When the dryer bearing is worn or dirty, it can cause damage or shearing of the drum axle, which will subsequently create a lot of noise. Similarly, some household appliances are equipped with a sensor that detects the dryness of the laundry: a defective bearing can affect the operation of the sensor and therefore increase the drying time.

If this happens to you, you will need to replace either the shaft or the drum with its bearing, depending on your dryer model.

To access the part, you need to snap off the drum from the inside, at the bottom. The drum shaft is either riveted or screwed onto the drum and slides into the bearing.

In conclusion, if your dryer won’t stop drying, it could be due to issues with the timer, moisture sensor, thermostat, door switch, or the electronic control board. Most of these problems are best addressed by professionals due to the inherent risks and complexity involved in working with electrical appliances. So, if your dryer continues to run endlessly, it’s advisable to reach out to a qualified technician for assistance.
