Lasko Fan Making Noise? Everything You Should Know

Lasko is one of the most well-known manufacturers of tower fans, although it is not immune to typical fan issues. After running your Lasko tower fan for a while, you could hear an odd noise. Is there anything you can do to stop it, and, more importantly, why does this happen?

The excessive accumulation of dust inside your Lasko tower fan, the fan placement on a surface that is not flat and stable enough, or loose screws in the various parts could all contribute to the noise. Each fan-related noise source manifests differently and calls for a specific course of action.

Investigating The Problem

You should first determine the type of noise your tower fan is making before taking any action to solve the issue. This might assist you in identifying the exact problem and the measures necessary to fix it.

Let’s review the many sounds Lasko Tower Fans make and what they indicate.

Shaking and Rattling Noise

Your fan may make a noise resembling the vibrating sound when two things meet. The majority of the time, this happens whenever the fan is turned on or oscillating.

Numerous problems could be the cause of this noise. One possible explanation for the rattling is that the fan’s base may be shaking against its resting surface, frequently occurring when a fan isn’t correctly maintained. It’s also possible that the fan’s loose components are crashing into one another. These types of noise might also be caused by debris accumulating inside the fans.

Scraping Or Screeching

Another sound that your fan could make is a metallic scraping or screeching sound. Depending on the underlying issue, this noise may be constant or intermittent.

Excessive dirt accumulation might cause friction in the fan blades, resulting in squeaking or scraping noises. The fan’s motor at the base may also be giving you problems. The noise level from your lover might be decreased by attending to these issues.

Constant Squeaking Noise

By slowly shifting the airflow back and forth, the oscillating motion of your Lasko tower fan makes it more effective at cooling down a broader area. Using a spinning mechanism, the fan is moved by plastic rollers to provide the oscillating motion.

But when these rollers deteriorate over time, you might hear a squeaking sound every time the fan rotates.

This noise will probably occur regularly, with a little pause between each squeak. It was evident that the revolving mechanism’s rollers, as opposed to the fan itself, were the problem.

How To Solve Lasko Fan Noise Issue

You can make your fan run silently by following the troubleshooting methods below. You can try one of the following actions by first identifying the noise.

Remove Any Dust From The Fan

Cleaning the fan is one of the simplest remedies that could reduce the noise level of your lover to normal. Dust, dirt, and other airborne debris can adhere to various components of the fan, particularly the blades, as it circulates air through it. This might prevent those components from moving smoothly and result in excessive noise.

Here’s how to clean the fan:

  • Turn off the fan’s power and unplug the power supply.
  • Disassemble the fan. The screws holding the plastic over the fan can be loosened and removed with a screwdriver.
  • After disassembling the tower, use a paper towel and cleaning spray to wipe down the vents and fans.
  • You can clean the vents with a vacuum instead of a paper towel and cleaning solution if that seems too inconvenient.

Place A Flat, Sturdy Surface For The Fan

Unusual noises may be heard if the surface your fan is sitting on is not adequately supporting it. The cover may be rattling from the fan’s movement, or the fan may be wobbling or shaking unevenly on the surface.

Regardless of the situation, the noise problem with your fan can be resolved by simply shifting the tower to a different surface. Put it on a stable surface that can handle the fan’s weight and motion without wobbling or making a sound.

Lubricate The Fan’s Pivot Point’s Rotating Mechanism

The spinning mechanism that drives the oscillating motion may need to be lubricated if you constantly hear a squeaking sound inside the fan while the tower oscillates on its base. Because of less friction, the mechanism will operate more quietly.

Here’s how to lubricate the rotating device:

  • When finished, disconnect the fan.
  • Take apart the tower’s exterior parts.
  • After you enter the tower’s interior, look for the rotating mechanism there.
  • Apply gasoline grease or similar lubrication to the tower’s plastic rollers where they rotate.
  • It works if the rollers still move freely and softly after reassembling the fan.

Tighten Unsecured Screws

Metal screws that offer the support the fan needs to function appropriately hold the various components of your fan together. The fan could become noisier than usual if these screws become loose due to frequent use and normal wear and tear.

Check the fan’s cover and the footing the tower is sitting on. Unscrew the lid and look inside the fan for any additional loose screws that might be the noise source if there is none. Locating the loose screws and adjusting them with a screwdriver will solve a problem relatively quickly.

Change The Oscillating Motor

If adjusting any loose screws and lubricating the internal parts of your fan don’t help, the oscillating motor may have entirely worn down past the point where it is still functional.

A solo engine for your tower fan might be available from a nearby retailer, but that may not be the case for other models. If that’s the situation, a functioning motor must be substituted. You’ll have to change the whole thing if you can’t find a solitary engine for your model. The Lasko website is your best bet for information.

How Should A Squeaking Fan Motor Be Lubricated?

Lasko Fan Making Noise

Your Lasko box fan began squeaking a while back, which was very bothersome. I typically turn on the fan at night to let some fresh air in through the window. But I was unable to go to sleep at all with this loudness. I had to take action. Until I discovered the answer, I researched online and read numerous publications.

The fan motor was merely being lubricated. I’ll outline the steps I took here so you can also fix your squeaking fan. Squeaking typically occurs when dust gets within the bearing. The strain between the metal parts becomes more intense due to the dust, resulting in this noise.

The Lasko fan motor is sealed, so we can’t open it up and clean it. The workaround is to apply oil to the dusty parts to ease the tension. To lubricate it, to put it another way Thus, the following is how to oil a fan motor:

Never clean or lubricate a fan while it is running. Detach the fan cage by loosening the screws on the back.

The blades should be taken off the metal shaft they are mounted on. To do that, you might need to loosen a lock bolt.

Using a fine tube or the oil bottle’s nose, spray oil into the bearing through the holes around the shaft.

Tools And Tips For Cleaning Lasko Fan

To make your fan squeaky clean, and free of bacteria and germs, I also discovered the best equipment and products for you. We offer usage instructions and our top cleaning tips for every product.


The variety of brushes available is enormous. When it comes to cleaning a fan, which method is the best?

Broad Brush

The back grills of a reader’s Breeze Machine were cleaned using his advice. In addition to a vacuum cleaner, he utilizes a flexible brush often used to clean jars and glasses. Utilizing a vacuum to draw in the air, use the brush to clean the grills.

Its bristle head’s delicate tips will gently scrape the dust off without damaging the plastic as they enter the grill’s crevices. To effectively reach the areas behind the grills and remove concealed dust, you can bend it just a little. To get rid of the dust before vacuuming, you may also use it on a fan motor. Make sure the brush is entirely dry before using. Don’t ever get the engine wet.


Use this duster if you don’t want to unscrew your fan but still need to clean the dust off the grills. Dense chenille microfiber is woven into a tube to form the duster’s cover. As a result, you may use the duster’s entire surface.

The duster cover’s microfibre is positively charged; thus, without using chemicals, it will draw in negatively charged dust.

As you dust a surface evenly, you can maintain the duster flat on the surface thanks to the handle’s clever design. Due to the flexibility of the plastic wand, it may be bent to fit the contour of whatever requires dusting. Fan grills are an excellent example of little objects for which the duster’s size is ideal. It might be less practical to utilize it with ceiling fans.

Concluding Remarks

If the weather is warm and it’s hard to keep comfortable, a good Lasko tower fan, such as the Lasko Electric Oscillating Tower Fan, will help.

The fan’s louder-than-usual operation may make it uncomfortable for you. Fortunately, finding the noise source and resolving it can increase the lifespan of your unit and maximize your investment.
