What is a door switch in a dryer?
A door switch is a device that is used to detect whether a door is open or closed.
Door switches are often used in security systems and can be found in a variety of other applications as well.
In most cases, a door switch will consist of two parts, such as a sensor and an actuator.
The sensor detects whether the door is open or closed, whereas the actuator activates the alarm or other components when the door is opened.
In most cases, an average dryer door switch measures just over an inch long, and they are generally white in color.
Where is the door switch located in the dryer?
The door switch is usually located around the door opening in the front panel or at the top of the door opening.
It is a small, rectangular button or lever (or a switch) mounted on the door that gets pushed when the door is closed.
It is connected to the two terminals on the opposite side, i.e., inside the dryer and to the dryer’s electrical system.
When the door is closed, the switch completes the circuit and allows the dryer to start.
You can always refer to the user manual of your dryer’s model and type to locate the door switch assembly in a better way.
In some dryers, the door switches can be found near the hinges that get pushed in as the door opens. This further disconnects the power to the dryer’s operation.
What are the symptoms of a bad door switch in a dryer?
If your dryer door switch is not working as it should, you may experience the below symptoms.
- The dryer will not start when the door is open or closed.
- The dryer will not stop when the door is opened.
- The dryer will not turn on at all.
So, if you are experiencing any of these issues, it is likely that your door switch needs to be replaced.
How to test the door switch in a dryer?
The door switch can easily be tested with a multimeter.
Here’s how you can do it:
- Locate and remove the door switch.
- Touch the multimeter’s probes to each of the door switch terminals.
- The needle in the multimeter should move and read zero ohms of resistance if the switch is working properly.
If there is no continuity, then it means that the door switch needs to be replaced.
How to replace the door switch in a dryer?
