Jul 29, 2023, 16:59pm

The hood produces a suction noise during operation, which may seem completely normal. However, some elements can degrade over time, and it’s not uncommon for this device to produce a different kind of extraneous noise. This is why it is important to overhaul the parts of the hood.

There may be crackling, popping, buzzing or rolling noise. You have to recognize what type of noise it is to know which part is causing the failure. It will then be necessary to check:

  • the filters
  • engine
  • the non-return valve

The extractor hood, also known as a range hood, is a vital part of a modern kitchen, reducing airborne grease, combustion products, smoke, and odors from cooking. While it is normal for an extractor hood to produce some sound when operating due to the fan motor, unusual or excessive noise can indicate a problem. This article will outline the possible reasons why your extractor hood might be making noise and provide potential solutions.

Why Does My Extractor Hood Make Noise?

Potential Causes and Solutions

1. Loose or Defective Fan Blades

The fan inside your extractor hood can become loose over time due to continuous vibration, or it might be defective due to damage or wear. This can result in noise as the fan spins.

Solution: Examine the fan blades. If they are loose, tighten them. If you see visible damage, consider replacing them. Always ensure the hood is off and unplugged before inspecting.

2. Motor Issues

The motor in your hood can also be a source of noise, especially if it’s old or defective. As the motor wears down, it may start to emit grinding or humming sounds.

Solution: If you suspect the motor is the issue, it’s often best to seek the help of a professional. Replacing a motor typically requires specialized knowledge and tools.

3. Clogged or Dirty Filter

Over time, the filter in your hood can become clogged with grease and other particles, causing the fan to work harder and produce more noise.

Solution: Regularly clean or replace the filters in your extractor hood to ensure optimum airflow and reduce strain on the fan.

4. Ductwork Problems

If your extractor hood is vented to the outside, the ductwork can also be a source of noise. Obstructions, damage, or improper installation can lead to increased noise levels.

Solution: Check your ductwork for any obstructions or damage. If you find any, clear the obstruction or repair the damage if possible. If the ductwork is improperly installed, you may need to consider having it reinstalled correctly.

Preventive Measures

Regular maintenance of your extractor hood can prevent many issues. Cleaning your hood and its filters regularly and ensuring all components are securely tightened can help maintain your hood in top working condition and reduce noise.

In conclusion, while a noisy extractor hood can be irritating, identifying the source of the noise can often lead to a straightforward solution. Whether you’re able to fix the issue yourself or need to call in a professional, the first step is understanding the possible causes.
