Why do KitchenAid Mixers Make Noise?

When it comes to reliable, long-lasting mixers, the KitchenAid mixer stands out. Since its creation, the KitchenAid mixer has saved numerous people's lives.

It is comparatively easy to use for food mixing. Simply combine all of the ingredients in the mixer, and it will quickly do the rest of the job. The KitchenAid mixer is renowned for its capability to process large quantities of thick food because of its sturdy and long-lasting metal frame.

Unfortunately, KitchenAid is not an exception when it comes to noisy stand mixers. Due to the necessity for a larger motor and all-metal gears, larger mixers may be noisier than smaller mixers. 

Direct Circuit (DC) and Alternate Circuit (AC) electric motors are used in KitchenAid mixers. When operating, despite having an "airplane-like" or harsh sound, brushless DC motors are quieter than AC motors, which produce the most noise.

When you buy a larger mixer after being used to a smaller one, it could first seem loud. Even among mixers that share the same model, there are distinct sound differences. The sound of squealing, screeching, knocking, or grinding is not normal for the KitchenAid mixer.

There are typically ten speeds on KitchenAid stand mixers. The noise level increases as soon as the lever is moved to increase speed. Definitely, it still makes noise even on the lowest setting.

A YouTube video below will let you hear the normal sound of two models of KitchenAid mixer in the lowest to highest settings.

What Are The Causes And Solutions Of The Loud Noises Made By KitchenAid Mixers?

Despite the KitchenAid mixer's reputation for versatility, loudness seems to be a common complaint among consumers. If you're seeking a fix for the noise issue with your KitchenAid mixer, here's how you approach it:

Old Or Insufficient Gear Grease

The KitchenAid mixer is made of sturdy metal due to its utility. High-tech components that make up the mixer include gear that needs to be properly and frequently greased for it to last a long period. 

The mixer will eventually start to lose shape, the gear will start to lose quality, the blades will start to lose touch, and some other sections of the mixer will start to lose touch if it is not greased.

Also, the mixer may no longer have enough lubricant to keep the gears spinning smoothly after years of operation. As a result, your mixer will start to create a lot of noise when it is in operation.

If you determine that grease is the cause of the noise coming from your mixer, we advise that you open it up, remove the old grease, and then put new grease in. After applying, make sure the grease is not dripping. After this, your mixer ought to operate normally.

A video demonstrating grease replacement is shown on YouTube below.

Increased Speed Level

The speed of your mixer is another factor contributing to its loud noises. Older models of the KitchenAid mixer might not be able to handle high speed, as opposed to more recent ones.

The motor of the earlier models of KitchenAid mixers will work hard because of the way they are constructed, and this may generate noise. If you have an older model of the KitchenAid mixer, it is recommended that you lower the speed at which the mixer operates.

Ingredient(s) Being Mixed

You might find that your KitchenAid mixer is working fine in some circumstances. How come it still makes a lot of noise, then? It's possible that the kind of ingredient your mixer is processing is what's making it noisy.

A few ingredients are very noisy and rough. They frequently bounce in the mixer's container when you are blending or combining these ingredients, making a loud noise. To determine which component is the noisiest, all you need to do is pay attention to your mixer and ingredients.

Worm Gear Failure

The worm gear in your KitchenAid mixer is the most frequent noise source. It seems reasonable that if something is wrong with the mixer, you would inspect the worm gear. It is a plastic gear that is installed in the motor and prevents the motor from failing or burning out.

The sound of the mixer can be one indicator that the worm gear has stopped functioning. Without the worm gear, your mixer will make a loud noise. 

We suggest that after determining that the worm gear is the source of the noise, you notify a technician and then get your mixer repaired. If your mixer is still under warranty, you can also take it in for replacement or free repair.

Low-Quality Parts

Although the quality of the KitchenAid mixer is uncompromised, there is a potential that you replaced some of its parts recently and used low-quality parts. 

Cheap parts have a greater chance of producing more noise, including shoddy connections and a lack of lubricant in the mixer's high-stress areas. To solve the issue, you need to get your mixer inspected and make sure the substandard parts are changed out with better ones.

Motor Brush Worn Out

The KitchenAid mixer type with the brushed motor might be to blame for the loud noise. This is because the brushed motor has magnets and is made to produce rotational movements. 

However, because the magnet has a higher polarity, the motor must work harder to grind the ingredients, creating a loud noise. In conclusion, if your mixer is equipped with a brushed motor, check if the stopper is at the bottom of the brush holder by looking at it. 

If it is the case, you need to replace the motor brushes and line them up correctly if you want them to work again quietly because they are worn out.

A YouTube video below will show you how to replace the motor brushes in your KitchenAid mixer.
