Why Is My Kitchen Extractor Fan Blowing?

A kitchen fan extractor can be a valuable tool for cooking. It can help improve the airflow in your kitchen, making it more comfortable and easier to cook.

Some people like to attach their kitchen fan extractor to the top of their refrigerators with a rubber band or a plastic bag clip.

In contrast, others prefer to use it as an unobtrusive stand-alone device that they install onto the wall beside their stovetop or countertops.

Your kitchen extractor fan is blowing because the filter is clogged and the fan blowing in the wrong direction. The fan will stop blowing if the breaker has flipped, or the fuse has tripped and there is a blockage (obstruction) in the airflow. If the light turns green, it will blow air out of your kitchen.

If you turn your kitchen extractor fan on and the light turns orange or red, that means that one of two things may happen:

Either something is blocking the flow of air from blowing out, or something is stopping it from turning back on.

If you turn your kitchen extractor fan on and the light turns green, the kitchen extractor fan will blow air out of your kitchen.


  1. If your kitchen extractor fan turns on and then off after a few seconds, it’s not functioning correctly.
  2. Your kitchen extractor fan should run smoothly and continuously. Contact a technician if your kitchen extractor fan turns on and off or appears to be not functioning correctly.
  3. If the following situations occur in the kitchen, the air is being blocked by:
  4. Grease and batter blocking the gap between the top of your kitchen ceiling and the top of your kitchen extractor fan.
  5. Steam, vapor, or vapor residue blocking the gap between the top of your kitchen ceiling and the top of your kitchen extractor fan.
  6. Liquid spilling in front of the kitchen extractor fan.
  7. Heavy smoke and steam blocking the gap between the top of your kitchen ceiling and the top of your kitchen extractor fan.
  8. Any grease, butter, or batter that gets too hot in front of your kitchen extractor fan should be checked.

How Can I Improve My Range Hood Suction?

You can improve your range hood function by replacing the motor and restoring your suction power.

This may not be a solution for everyone, but it is a cost-effective alternative for those who want to replace the motor but don’t want to pay for professionals.

You can save money through this process and enjoy better ventilation. With range hoods, what fuels their suction power is a question of importance.

The common practice is to remove the wood panels and replace them with plastic ones that allow you to use less energy.

This means that you get a cleaner model, but your ventilation power reduces slightly.

However, the suction power of your hood will restore by replacing the motors and filters with upgraded versions or by installing a new exhaust fan.

With your range hood suction power, there are some steps that you can take to ensure that it’s effective.

For example, if you have the original wood panels, replace them with plywood ones that are more suitable for this purpose.

Meaning you will use less energy and get better performance from the hood.

However, you should not forget about the filters, as they need cleaning or replacement regularly for your kitchen to get a clean air supply.

Why Is My Extractor Fan Not Extracting?

Your extractor fan is not extracting because it boasts rust. The fan may be close to the end of its life cycle, so it’s time to replace it. Here are some tips on how to get a new one.

To remove the fan and determine which parts need replacement.

  1. Unplug the power cord from the wall outlet and remove all screws securing the front and back paneling to the rest of your extractor fan
  2. Unscrew all screws that hold together your extractor fan blades, then take them out of their housing
  3. Turn the blades counter-clockwise a bit to get them all free, and then lift out your old extractor fan and put the new one away.
  4. Give the entire thing a wipe-off with cleaner (not solvent) and attach all screws, bolts, and washers that you took out of the old unit, then replace them in its housing.
  5. Put everything back together again, and re-wire it.

After you replace your extractor fan(Amazon Link) if you still have the same problem, then check your venting system.

If a backdraft prevents air from outside from drawing in the house, clean out or replace any vents or exhausts visible in your roof space.

You can use an electric drill with a drill bit to open up any blocked vents.

Should You Feel Suction From An Extractor Fan?

Yes. You should feel suction from an extractor fan. The extractor will remove heavily filled air and replace it with clean air.

This is one of the easiest ways to feel better in a room full of people, as fumes and smells quickly and efficiently when using this type of system.

You can improve the ventilation of a room by installing ceiling fans because as air circulates throughout the room, it will release odors and fumes.

Another benefit of installing ceiling fans is that they can also help circulate air over a one-floor level, so a room doesn’t remain warm at just the lower level. This can reduce comfort.

Why Does My Vent Make Noise When It’s Windy?

Your vent makes noise when it’s windy because the wind can put pressure on the vent, and the vents have a different size depending on which side of your house you live in (if you’re in a two-story building).

It makes more noise when it’s windy because the vent has more chances to make a noise with more pressure.

The Noise-free vent has a better way of stopping the noise and fits the size of your vent better so that it doesn’t make noise.

You could buy some vents or a screen for your vent to fix this problem. You could also put some objects in front of your vent to block it so no wind can get in there and make noise.

A product made to make vents not make noise is usually called the “Noise-free vent.” It’s extremely thin, and it twists itself.

The noise-free vent should fit better than regular ones because it’s tiny and thin. Its shape will fit your vent well, and the wind cannot put pressure on it hard.

Another option is to screen your vent; you can find what you need on the internet.

If you block the vent ultimately to make sure no wind can get in, then you could put a ledge in front of your vent.

Can You Reverse An Extractor Fan?

No. You cannot reverse an extractor fan because the motor direction is crucial to operate.

The motor of an extractor fan spins one way, which in turn pushes air out and makes it rise; this would cause a counter-clockwise rotation when viewed from above.

Reversing an extractor fan’s rotation means the air gets pushed in instead of forced out. This creates a “sucking” airflow with a clockwise rotation when viewed from above.

Either way, the direction of rotation makes a reversing extractor fan different. There are several ways to put it back into a clockwise position without ruining it.

You can reverse the motor, reverse the motor direction and change the blade pitch on an existing fan. The speed will not affect the direction of rotation.

You will find the extractor fans used in bathrooms and kitchens to remove stale air to prevent mildew and grow mold in their home.

Some water damage protection protectors prevent the extractor fan from water damage. An extractor fan comprises a fan motor and blade section attached to a flexible pipe.

The pipe extends out of the wall with an outlet at the end. These fans move air; they draw air into the bathroom or home and send it out through the other end.

Does The Exhaust Fan Bring In The Fresh Air?

Yes. There is fresh air inside, even if it’s coming through the exhaust fan.There is twice as much fresh air inside as outside. This is because of the principle of ventilation.

While you’re on your computer or laptop, you are helping pull in fresh air from outside, and this will circulate throughout your home.

Speaking of your bathroom, you’ll notice no exhaust fan. This is because it’s already a self-contained area with very few contaminants.

When too much moisture and humidity occurs in the bathroom, an exhaust fan would be necessary to keep your relative humidity level at 50%.

Can A Single-Phase Fan Run Backward?

Yes. Specifically, this fan can run backward to increase its efficiency.

Those wondering how a single-phase fan can do that by hitting the propeller’s blades at a different angle than the natural position.

This will change the speed of one side of the fan and, alternately, increase its total power output.

The downside is that this process increases noise and blade vibrations, affecting its usability as an office or household fan.

How Does A Single-Phase Fan Operate?

A single-phase induction motor runs on an electronically controlled AC through the help of a small device called an inverter.

This converter alters or inverts the flow of the electricity to match the speed and power requirements of a fan.

The advantage is that this type of motor is not as bulky as three-phase AC fans, which makes them easier to install and transport.

An induction motor works by inducing alternating current from the incoming source, thus turning it into rotational motion.

Propeller Angle Alteration

Since this fan operates on a single-phase AC, the inverter can change the energy into a reverse movement of the fan.

The process works by altering the angle of one side of the propellers to increase its speed.

A single-rotor induction motor turns at a fixed rate regardless of its position concerning the power source.

This means that altering one side will offset its rotation, generating more power output.

This fan rotates in the opposite direction from a regular rotation and hits both sides of the propeller at different angles during the process.

Increased Noise

This process increases the noise of this fan since it generates extra vibration to increase its power output.

This can be a problem when using these fans in residential homes or offices, with some quietness requirement.

Increasing the speed will also increase heat levels, unsuitable for long-term usage.

Higher Operating Temperature

Electricity passes through the motor, which means its power gets sourced directly linked to the heat produced.

If a fan is operating at high speed, more electricity will become needed to maintain it.

If there is less power supply, the motor’s temperature will increase, leading to severe damage.

Marine Impact And Toughness

Induction motors are highly resistant to water and other environmental conditions.

However, induction motors create sound waves that can get considered a hazard for marine use.

For example, aviation uses induction motors, but they are not suitable for marine use.

Additionally, the exhaust is more susceptible to damage than other motors, which produce more heat.

Lower Reliability

There are many reasons why induction motors have been considered less reliable than three-phase AC fans.

These reasons include the inconsistency in power changes, increased noise levels, and greater susceptibility to water damage.

This low reliability means that you must check the motor frequently for defects or malfunctioning parts.

However, this is a minor drawback compared to the high price of these motors and the fact that they are hard to repair in the case of excessive damage.

Do All Fans Have A Direction Switch?

No. Three different fan types have a separate direction switch. For example, this does not limit ceiling fans to a vertical or horizontal rotation.

You can also revolve from side to side or take flight and rotate in a circular motion.

The Three Types Of Fans Are:

  1. Ceiling Fans
  2. Table Fans
  3. Wall Fans

However, there is only one direction switch. Every fan you own can rotate in one direction only.

The direction switch lets you choose from among the three different fan types described above. So, all your fans will rotate in the same direction.

Merely changing the direction of rotation of a fan does not affect the direction of the airflow.

All ceiling fans rotate in a counter-clockwise and clockwise pattern, although some rotate only slightly to either side, and the operator may not feel it.

Why is my kitchen extractor fan blowing?

The primary difference between a ceiling fan and a table fan is that a ceiling fan has blades angled outward.

While table fans have blades turned in (so they will face you when you’re standing directly beneath them).


This post has well described the extractor function. It’s an important device that helps maintain the relative humidity within an environment.

We have read about how the extractor fan works. We also know that there are multiple types of extraction fans, and their working principles are different.
