How to Fix a Dryer That Won’t Stop Running

Understanding the Problem: Common Causes of a Dryer that Won’t Stop Running

Dryer that Won't Stop Running

If you’re dealing with a dryer that won’t stop running, the first thing to know is that there are several common causes. Here are some of the most likely reasons why your dryer won’t turn off when it’s supposed to:

The Timer is Broken

The timer is what controls the length of your dryer cycle. If the timer is broken, it may not be telling your dryer when to stop. One way to tell if your timer is the problem is to listen carefully to your dryer. If you don’t hear any ticking sounds coming from the timer, it may be faulty. You can confirm this by using a multimeter to test the timer’s continuity. If it’s not functioning correctly, you’ll need to replace it with a compatible replacement part.

A Faulty Thermostat

Another common cause of a dryer that won’t stop running is a faulty thermostat. The job of the thermostat is to monitor the temperature inside the drum and adjust it as necessary. If the thermostat is malfunctioning, it may keep your dryer running even when it’s completed its cycle. One way to check if your thermostat is working correctly is to use a multimeter to test its continuity. If it’s not functional, you’ll need to replace it to solve the problem.

The Door Switch is Broken

Your dryer’s door switch is what tells your device whether the door is open or closed. If the switch is malfunctioning, it may not be communicating properly with your dryer. In that case, your dryer may not know whether it should keep running or stop. To test whether your door switch is faulty, try to manually depress the switch while the dryer is running. If it stops when you depress the switch, the problem may be a faulty switch. Check the switch to make sure it’s properly wired and replace it if necessary.

The Start Switch is Stuck

Another cause of a dryer that won’t stop running is a stuck start switch. The start switch is what lets you turn on the dryer in the first place. If it’s stuck in the “on” position, it will keep your dryer running even when it should have stopped. To unstick the switch, try pushing down lightly on it to see if that resolves the problem. If not, you may need to replace the start switch to get your dryer back to normal operation.

A Malfunctioning Motor

The motor is what drives the drum to spin. If the motor is malfunctioning, it may keep the drum running even when it’s supposed to stop. One way to test whether the motor is at fault is to listen to the noise it’s making. If your dryer is making strange, loud, or irregular noises, your motor may need to be replaced. Additionally, you can test the motor’s continuity with a multimeter to see whether it’s functioning okay.

Regardless of what’s causing your dryer to keep running, the good news is that most of these problems can be fixed quickly. By understanding some of the most common causes and performing a few simple tests, you should be able to identify the issue and start restoring your dryer to its intended operation.

When your dryer won’t stop running, it can be frustrating. Fortunately, the problem isn’t always serious and can be fixed with minimal effort. Before taking it to a professional, it’s essential to start by checking the basic components of your dryer: the thermostat, timer, and start switch.

The thermostat regulates the temperature in the dryer by turning it off and on as needed. If the thermostat is faulty, it might prevent the dryer from turning off when it’s supposed to. To check if the thermostat is the cause of your problem, you’ll need to use a multimeter or a continuity tester to check its continuity. If it’s defective, it’ll need to be replaced.

The timer is also essential for controlling the dryer’s duration and ensuring it doesn’t run beyond the recommended time. Sometimes, the timer’s motor may become defective, causing the timer to keep running even when the dryer isn’t in use. It might also fail to stop running once it completes a cycle. If you suspect the timer is the problem, start by checking for physical damage and then testing it with a multimeter. If it’s defective, it should be replaced.

The start switch is activated when you press the button to turn on the dryer. If the switch is stuck in the on position, the dryer won’t stop running, even when it’s supposed to. Sometimes, dirt and debris may clog the switch, preventing it from functioning as required. To fix this, try cleaning the switch with a soft-bristled brush and a cleaning agent. If it’s still not working, inspect the switch for physical damage and replace it if necessary.

In conclusion, if your dryer won’t stop running, it’s likely to be an issue with the basic components. Checking the thermostat, timer, and start switch is simple, and you can easily fix the problem with the right tools. However, if the problem persists even after inspecting and replacing these components, it might be best to seek professional help.
