Setup and Installation
Follow these steps carefully to replace the control button PCB. If you are unsure at any point, consult a qualified technician.
- Prepare for Installation:
- Ensure the cooker hood is completely disconnected from the main power supply.
- Gather necessary tools: screwdrivers (Phillips and flathead), possibly pliers, and a camera to document wiring.
- Access the Existing PCB:
- Depending on your cooker hood model, you may need to remove filters, light covers, or decorative panels to access the control panel assembly. Refer to your cooker hood's specific service manual for detailed access instructions.
- Carefully locate the existing control button PCB.
- Document Wiring:
- Before disconnecting any wires, take clear photographs of all wire connections to the old PCB. Note the color and position of each wire. This is crucial for correct reassembly.
- Disconnect the Old PCB:
- Carefully disconnect all wires from the old PCB. Note if any connectors are unique or keyed.
- Unscrew or unclip the old PCB from its mounting points.
- Install the New PCB:
- Position the new control button PCB (Model 15100031) in the same location as the old one.
- Secure the new PCB using the original screws or clips. Ensure it is firmly seated.

- Reassemble the Cooker Hood:
- Once all connections are secure, reattach any panels, light covers, or filters that were removed.
- Restore Power and Test:
- Restore power to the cooker hood at the main circuit breaker.
- Test all functions of the control panel (fan speeds, lights, etc.) to ensure the new PCB is working correctly.
Operating Instructions
This PCB controls the various functions of your cooker hood via its integrated buttons. Once installed, the operation should be intuitive and consistent with your cooker hood's original design.
- Power On/Off: Typically, one button controls the main power to the fan and lights.
- Fan Speed Selection: Multiple buttons or a single button with sequential presses will adjust the fan speed (e.g., Low, Medium, High).
- Light Control: A dedicated button usually controls the cooker hood's lighting.
Refer to your cooker hood's primary user manual for specific button functions and operational sequences.
Maintenance
The control button PCB itself requires minimal maintenance. However, proper care of the surrounding control panel can extend its lifespan.
- Cleaning the Control Panel: Ensure the cooker hood is powered off before cleaning. Use a soft, damp cloth with a mild, non-abrasive cleaner to wipe the surface of the control panel. Avoid spraying liquids directly onto the buttons or gaps.
- Avoid Excessive Force: Do not press the buttons with excessive force, as this can damage the internal mechanisms or the PCB.
Troubleshooting
If you encounter issues after installing the new PCB, consider the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Cooker hood does not power on after PCB replacement. | No power to the unit; incorrect wiring; faulty PCB. | Check circuit breaker. Verify all wire connections are correct and secure according to your documentation. Ensure the PCB is correctly seated. |
| Specific buttons do not respond. | Loose connection; damaged button mechanism; faulty PCB. | Check wiring to the specific button. Inspect the button for physical damage. If issues persist, the PCB may be faulty. |
| Fan or lights operate intermittently. | Loose wiring; intermittent fault in PCB. | Ensure all connections are tight. If the problem continues, professional diagnosis may be required. |
If troubleshooting steps do not resolve the issue, it is recommended to contact a qualified service technician.
