The hood’s motor capacitor serves as a battery for the motor. It stores energy and releases it when using the hood. It supplies the engine with power so that it is more efficient. If it is defective, the hood cannot work.
Check and/or change the motor capacitor of your hood if:
- the hood sucks badly;
- the hood no longer sucks at all;
- the hood motor makes noise.
iThe motor capacitor is located inside the cooker hood, in the motor housing.
The motor capacitor plays a crucial role in an extractor hood. It helps start the motor by providing a high-voltage jolt, and it ensures the motor maintains a consistent speed. Over time, the capacitor can wear out, leading to a motor that struggles to start or one that fails to maintain its speed. If you’re facing such issues, it’s quite possible you need to test and potentially replace the motor capacitor. This article will guide you through this process, step by step.
- A multimeter to test the capacitor.
- A replacement motor capacitor compatible with your extractor hood.
- A screwdriver set.
- Safety gloves and eyewear.
Testing the Motor Capacitor
Safety is paramount when dealing with electrical components. Ensure that the extractor hood is unplugged from the power source before proceeding.
- Locate the Capacitor: The motor capacitor is typically housed within the main body of the extractor hood, close to the motor. Refer to your hood’s manual to locate it precisely.
- Remove the Capacitor: Carefully disconnect the capacitor from the hood. It is typically connected via a couple of wires. Make a note or take a picture of the wiring before you disconnect to ensure correct reconnection later.
- Test with a Multimeter: Set your multimeter to the capacitance setting. Place the multimeter leads on the capacitor terminals. The reading should match the rating specified on the capacitor. If it doesn’t, or if there’s no reading, the capacitor is likely faulty and needs replacement.
Changing the Motor Capacitor
If you’ve determined the motor capacitor is indeed faulty, it’s time to replace it.
- Safety First: Ensure the extractor hood is unplugged before you start working.
- Remove the Faulty Capacitor: Using your screwdriver, disconnect the faulty capacitor from its mount. Be sure to disconnect the wires connected to it as well. Remember to wear safety gloves while handling electrical components.
- Install the New Capacitor: Connect the new capacitor to the hood. Make sure to connect the wires to the same terminals as the old capacitor. Secure the capacitor in its mount.
- Test the Hood: Reconnect the power and test the extractor hood. If the motor starts without issues and maintains its speed, you’ve successfully replaced the motor capacitor.
In conclusion, although the process of testing and changing the motor capacitor of an extractor hood might seem complicated, it can be done with the right tools, some patience, and proper safety precautions. However, if you’re not comfortable working with electrical appliances or if your hood is still under warranty, it’s best to contact a professional for assistance.
