A clothes dryer requires regular maintenance. It is necessary to clean and change the filters regularly: during drying, the clothes create fluff which will become lodged inside the machine, which can prevent it from working properly.
It may happen that the dryer does not turn on. It will then be necessary to check and test the elements which may be responsible for this starting fault:
- The electric plug
- the noise filter
- the switch
- the electronic card
A dryer that won’t turn on can be a frustrating and inconvenient problem, especially when you have a pile of laundry to dry. There are several potential reasons why your dryer is not starting, ranging from simple issues to more complex problems. In this troubleshooting guide, we will explore some common causes and steps to help you diagnose and resolve the issue.
1. Check the Power Supply
The first and most basic step is to check the power supply:
- Ensure the dryer is properly plugged into a functioning electrical outlet. Sometimes, the plug may have come loose or disconnected.
- Check the circuit breaker or fuse box dedicated to the dryer. If the breaker has tripped or the fuse has blown, reset or replace it accordingly.
- Test the electrical outlet with another device to confirm that it is providing power.
2. Verify the Door Switch
Most dryers have a door switch that prevents the dryer from starting if the door is not fully closed. If the door switch is faulty or misaligned, it may be the reason why your dryer won’t turn on. Open the dryer door and press the door switch manually to ensure it engages properly. If the switch is not engaging, it may need to be replaced.
3. Check the Thermal Fuse
The thermal fuse is a safety feature that blows if the dryer overheats. If the thermal fuse is blown, it will prevent the dryer from starting. The thermal fuse is usually located on the blower housing or near the heating element. To check the thermal fuse, you will need to access the back panel of the dryer and use a multimeter to test its continuity. If the thermal fuse is defective, it will need to be replaced.
4. Inspect the Start Switch or Timer
The start switch or timer in the dryer can become faulty over time. If these components are defective, they can prevent the dryer from starting. Use a multimeter to test the continuity of the start switch and timer. If either of them is not functioning correctly, they will need to be replaced.
5. Check the Drive Motor
The drive motor is responsible for spinning the dryer drum. If the motor is defective or has burnt out, the dryer won’t turn on. Test the motor using a multimeter to check its continuity. If the motor is not working, it will need to be replaced.
6. Inspect the Drive Belt
The drive belt connects the drive motor to the dryer drum. If the belt is broken or worn out, the drum will not spin, and the dryer won’t start. Inspect the drive belt for any signs of damage and replace it if necessary.
7. Examine the Control Board
Modern dryers often have electronic control boards that manage various functions. If the control board is defective or has a blown fuse, it can prevent the dryer from starting. Inspect the control board for visible damage and test its functionality with a multimeter. If the control board is faulty, it may need to be repaired or replaced.
CHECK THE NOISE FILTER OF THE DRYER
The noise filter is connected to the electrical cord inside the machine. It is usually located above the device.
- Locate the noise reduction filter and visually check its condition: it should not be blackened, it should not have burn marks or damaged components.
- Then disconnect the wires or connector coming out on the electronic board.
- Connect your device. If it works, the noise filter is defective and must be replaced.
- You can also test the noise filter under voltage: place the test leads of the multimeter on the two connection points of the noise suppressor. If you get a value close to 230 volts, it is good.
A dryer that won’t turn on can be caused by various issues, ranging from simple to more complex problems. By following the troubleshooting steps mentioned above, you can identify the most likely cause of the problem and potentially resolve it on your own. However, if you are unsure about the troubleshooting process or lack the necessary skills and tools, it is best to seek professional help from a qualified appliance repair technician. They can diagnose the issue accurately and safely fix the problem, ensuring your dryer is back up and running efficiently. Remember, always prioritize safety when working with electrical appliances and disconnect the dryer from the power supply before attempting any repairs.
