Why Does My Ventilator Hood Suck Poorly?

Jul 29, 2023, 17:17pm

The hood turns out to be an indispensable appliance for the kitchen. It allows the suction of grease and smoke from cooked dishes and thus ventilates the kitchen. For extractor hoods, two types of evacuation exist: either evacuation by extraction or by recycling. Most hoods have both modes, recirculation and exhaust, but some only have one of them.

However, it is not uncommon for this type of device to have a suction failure, which can be problematic. It will then be necessary to check and test the various elements responsible for this failure:

  • Engine
  • The capacitor
  • The non-return valve

The ventilator hood, also known as a range or extractor hood, plays a vital role in maintaining a pleasant and healthy environment in your kitchen by removing smoke, steam, odors, and airborne grease particles. However, if it seems to be drawing air poorly or not at all, you may need to identify and resolve certain issues. This article will outline the possible reasons why your hood might be extracting air inadequately and offer solutions to correct the problem.

Why Does My Ventilator Hood Suck Poorly?

Clogged or Dirty Filters

Perhaps the most common reason for a hood to perform poorly is a dirty or clogged filter. Over time, the filters in your hood can accumulate grease and other particles, which can obstruct the flow of air.

Solution: Clean or replace the filters regularly according to the manufacturer’s instructions. Metal filters can usually be cleaned, often in the dishwasher, while charcoal filters typically need to be replaced.

Insufficient Hood Size or Power

If your hood is too small or doesn’t have enough power for your cooktop, it may not be able to effectively extract air. This is especially true if you frequently cook on all burners or do a lot of high-heat cooking.

Solution: When choosing a hood, ensure it is at least as wide as your cooktop and that its extraction rate is suitable for the size of your kitchen. As a general rule, the hood should be able to change the air in your kitchen 10-12 times per hour.

Incorrect Installation

Improper installation can also lead to poor extraction. This can include issues like the hood being installed too high above the cooktop, or ductwork that is too long or has too many bends.

Solution: Refer to the manufacturer’s instructions for proper installation, including the recommended height above the cooktop and ductwork specifications. If necessary, you may need to have the hood reinstalled correctly.

Ductwork Problems

If your hood is vented to the outside, problems with the ductwork can cause poor extraction. This includes obstructions in the duct, or leaks that allow air to escape before it reaches the outside.

Solution: Check the ductwork for obstructions and remove them if possible. If there are leaks, they will need to be sealed.

Faulty Fan Motor

The fan motor in your hood could also be a source of the problem. If it’s not operating at full power or has stopped working entirely, the hood won’t be able to effectively draw air.

Solution: If you suspect the fan motor might be the issue, it’s often best to seek professional help. Replacing a motor generally requires specialized knowledge and tools.

When to Call a Professional

While some of these issues can be addressed by a knowledgeable homeowner, others may require professional assistance, especially when dealing with electrical components or installation problems. If you’re not confident about any part of the troubleshooting or repair process, it’s best to call in a professional.

In conclusion, several factors can contribute to your ventilator hood’s poor performance. By understanding these potential issues, you can take the appropriate steps to ensure that your hood effectively removes smoke, steam, and odors from your kitchen, creating a healthier and more pleasant cooking environment.
