The tumble dryer is a complementary household appliance to the washing machine, which works on an internal heating system. The air is sucked in from the outside by a turbine, it is then heated by the resistors of the dryer. The moist air turns into water which is finally stored in a collection tank. Like any other device, it is important to ensure that all its parts are always in good condition.
The dryer is an electrical device which consists of several electronic components which rests on a card: the electronic card. This card has the role of supplying all the components of the device. Indeed, it ensures the proper functioning of the control system of your device. It contains the program that maintains communication between the control system and the electronic system.
Over time and use, it happens that the dryer encounters problems at this level, either a component that burns out or the card itself following a short circuit or overvoltage.
The signs that show a problem with the card can be various, but most often you can notice that:
- the dryer does not turn on,
- the dryer does not spin,
- no program starts
- the dryer does not heat up.
After examining, if the problem comes from the electronic card, it is necessary to replace it without further delay. Since the operation is simple, you can do it by yourself.
For most models, the electronic board is located on the control panel at the front of the device. To access it, you must remove the top panel.
The electronic control board, also known as the main control board or PCB (Printed Circuit Board), is a critical component in modern dryers. It controls various functions, settings, and timing during the drying cycle. If your dryer is experiencing issues like failure to start, not heating, or erratic behavior, a faulty control board might be the culprit. Changing the electronic control board can be a bit daunting, but with the right tools and guidance, you can successfully replace it. In this step-by-step guide, we will walk you through the process of changing the electronic control board of a dryer.
Step 1: Safety First
Before you begin any repair work on your dryer, always prioritize safety. Ensure the dryer is disconnected from the power supply by unplugging it from the electrical outlet or switching off the circuit breaker dedicated to the dryer.
Step 2: Access the Control Panel
To access the electronic control board, you will need to open the dryer’s control panel. The specific steps to access the control panel may vary depending on your dryer model. Generally, you will need to:
- Remove any screws or clips securing the dryer’s top panel to the cabinet. Slide a putty knife or a similar tool between the top and front panels to release any hidden clips.
- Lift the top panel and prop it up securely.
- Locate and remove the screws or clips securing the dryer’s control panel to the front panel.
- Carefully tilt the control panel forward to access the electronic control board and other components.
Step 3: Disconnect Wiring
Before removing the electronic control board, carefully disconnect the wiring harnesses connected to it. Take note of the location and arrangement of the wires to ensure you can reconnect them correctly later.
Step 4: Remove the Old Electronic Control Board
With the wiring disconnected, you can now remove the old electronic control board from the control panel. It may be secured with screws, clips, or fasteners. Remove any attachments and gently lift out the electronic control board.
Step 5: Install the New Electronic Control Board
Position the new electronic control board in the control panel, aligning it with the corresponding holes or slots. Secure it in place using the appropriate screws, clips, or fasteners.
Step 6: Reconnect Wiring
Carefully reconnect the wiring harnesses to the new electronic control board. Make sure each wire is attached to the correct terminal based on the notes you took during disconnection.
Step 7: Reassemble the Dryer
With the new electronic control board installed and the wiring reconnected, it’s time to reassemble the dryer. Reverse the steps you followed to access the control panel and secure it back onto the front panel.
Step 8: Test the Dryer
Before pushing the dryer back into its designated spot, perform a test run to check if the new electronic control board is functioning correctly. Turn on the dryer and test different drying cycles and settings to ensure proper operation.
Step 9: Final Adjustments
If you encounter any issues with the new electronic control board during the test run, double-check the installation and wiring connections. Make any necessary adjustments to ensure smooth and accurate operation.
Changing the electronic control board of a dryer may seem daunting, but with the right guidance, it is a manageable task. By following this step-by-step guide, you can successfully replace this critical component and restore full functionality to your dryer. Properly functioning electronic control board ensures accurate timing, control over settings, and reliable drying performance. However, if you encounter any difficulties during the process or have concerns about handling the repair, it’s always best to seek assistance from a professional dryer technician. With the new electronic control board in place, you can continue to enjoy efficient and effective drying with your dryer.
