Range Hood Not Pulling Air Properly

Range hood not pulling air properly. If you’ve noticed that your functioning range hood isn’t pulling as much air as it once did, you might be experiencing an issue with the fan or motor.

You can check to ensure those parts are working by temporarily hooking up a lamp or radio to the fan and seeing if they light up or play music when turned on.

You can also see if there is any visible damage on either part (don’t touch it, of course). Lastly, clean off the filters to ensure they’re not blocked by grease and lint.

Range Hood Not Pulling Air Properly

We will discuss some of the most common culprits when a range hood is not pulling air properly.

1. Clogged Air Filters

Clogged Air Filters

Range hoods are divided into two categories. The first recirculates air, while the second exhaust it from the kitchen.

The main difference is that the recirculating ones also contain a carbon filter to remove any contaminants they capture before releasing them back into your kitchen.

When these filters become clogged, your range hood’s ability to exhaust air from your kitchen may suffer!


  • It’s simple to change the filters on your range hood.
  • Remove the exterior vent panel from your microwave/fan oven (keep this handy, wash it, and replace it for storage).
  • Replace the one you’re now using with a new one purchased at any nearby hardware store.

2. Using the Incorrect Air Duct

To operate at full capacity, a range hood vent needs a smooth, rigid inner surface to guarantee adequate extraction of chemicals that pollute or are potentially harmful to the environment.

Flexible aluminum air ducts do not meet these requirements because they bend too easily and say they don’t travel into the internal surfaces of your range hood correctly.


  • When taking up residence in your new home or building your own use ducts made of steel for the venting attached to your range hood that removes fumes and smoke from the kitchen.

3. Broken Fan Blade

When managing the airflow to such a device, the fans inside your range hood can be quite handy. They’re what let you eliminate aromas in your kitchen or help distribute odors from meals over the room while you’re cooking.

Try replacing your old ones with new ones! This may or may not always work, but if you find that no light is reflecting off of your fan and that air is still going through it, you probably have a basic fan problem – time to replace the blades!


  • Disconnect any related wires and remove the old fan before removing the range hood’s outer panel.
  • After changing the outer panel install the new one.
  • Reconnect the wires previously attached to the old fan.
  • Reassemble all of your range hood’s inner components.

4. Broken Moter

A motor is one of the most expensive components to replace in a range hood, and it can easily eat up all of your profits.

This component is essentially the heart or engine of your appliance, and any malfunction can cause an explosion, which will be catastrophic.

If you’ve tried all of the above solutions and still your range hood isn’t pulling air as it should, there’s a good chance something might be wrong with the motor.


  • Although replacement hood motors may not be a challenge for some technicians, they are serious enough jobs requiring experience. So you will need to call a technician whom you can trust.


How can I improve my range hood suction?

Cleaning the filter on your range hood every three to six weeks will help ensure that it runs efficiently and doesn’t get clogged with grease and dirt.

If you don’t already have this well-known maintenance practice in place, keep reading for more information!

How much suction should a range hood have?

To figure out how many of your range hoods have, multiply the width of your stove by ten. If you had a 36, for example, “You would utilize 360 if you replaced your range hood with an electric one.

If you’ve got a 34, you’re in luck. “You would use 3200 if you had a gas range hood and want to upgrade to an electric stove with double the BTU (110,000).


Range hood not pulling air properly. Making sure your hood is in good functioning order will assist you in keeping your kitchen clean! Issues can arise quickly when a hood fails to pull air as it should.
