If your dryer won’t stop running, there are a few potential issues to check, such as a faulty control board, a malfunctioning door lock, or a broken timer. For a detailed guide on how to identify and fix these issues, read the article below. Learn more about our dryer repair services:

Description and Troubleshooting of Problems
Faulty Control Board
When your dryer doesn’t stop after opening the door or after the drying cycle is complete, the issue could be with the control board. It’s not a common problem, but it does happen. Often, this occurs after power surges or a power outage while the dryer is running. In this case, the relay on the control board that controls the system gets stuck in a closed position, and when it’s time to stop or end the drying cycle, it can’t disconnect because it’s “stuck” in the closed state. You may notice that the drying cycle seems finished, and the display might turn off like the dryer is off, but it keeps running. In this situation, you need to disconnect the power to the dryer and never try to fix it yourself, as the dryer runs on 220 volts, which can be very dangerous.

Door Lock Is Not Working
The problem with the door lock might be that it’s stuck, acting as if the door is still locked. When you open the door, it doesn’t release, and your dryer thinks the door is still closed, so it doesn’t stop running. You can check this by opening the door — the dryer should stop. If this doesn’t happen, you can try turning it off using the control panel. If the dryer turns off and then starts again when you turn it back on, it’s likely an issue with the door lock.

The Timer Is Broken
In older dryer models, instead of a control board, a timer is used, which functions similarly to control the start and stop of the dryer. The timer works like a clock; you set the drying time, and it runs the drying process for that set duration, stopping when the time is up. There are a few common problems with the timer. First, it should tick when the dryer is running and count down the time. If you set the timer for 20 minutes and it stays stuck on that time without counting down, it’s likely that it’s not working properly. In another case, it may count the time but fail to stop the dryer by disconnecting the contacts, which might indicate an issue inside the timer with the contact group. I believe that dryers with timers are much more reliable than those with control boards. From experience, dryers with timers tend to last much longer, and they are less affected by voltage fluctuations compared to newer dryers, which have many sensors and electronics that are more sensitive to irregular conditions.
