Are you asking yourself, “Is my KitchenAid mixer noisy?” You’re not alone. Approximately 80% of KitchenAid stand mixers are noisy. The noise varies according to size, with larger mixers being noisier than smaller models. Factors that affect mixer noise include the Brush motor, worm gear, and the height of the head. If you’d like to know the cause of the noise, read this article.
Larger mixers are louder than smaller mixers
The difference between smaller and larger KitchenAid mixers is mainly determined by the size and power of the motor. Larger KitchenAid mixers have stronger motors and can process thick foods. These mixers have sturdy metal frames, larger motors and all-metal gears. They also use brushless DC motors, which are quieter than AC motors. Smaller KitchenAid mixers make less noise than larger models.
The most expensive KitchenAid mixer is the Ankarsrum Original. It is surprisingly quiet and powerful, with 600 watts of power. It comes with a seven-year motor warranty and a host of other features. This stand mixer is great for many different tasks in the kitchen, including bread making, and even serves as a juicer, pasta roller, blender, and food processor.
Brush motor causes noise
If your Kitchenaid mixer is making a buzzing noise, the problem is likely due to a faulty motor. The motor assembly is responsible for controlling the speed and starting routine. Most motor systems have a starter, which means they start at zero RPM and switch over to another electrical configuration once significant RPM is achieved. If this feature is not working properly, the motor will make an annoying sound, similar to the sound of a raging magnetic monster. In some cases, this noise is caused by an eccentric rotor or mis-machined housing.
The most common cause of motor noise is windage. Windage noise occurs when turbulent air flows pass over obstructions near the rotating part. Ideally, these obstructions should be minimized to prevent windage noise. Regardless of the source, windage noise is often characterized by a wide range of frequencies and no pure-tone components. It’s important to determine what is causing the noise before you attempt any repairs.
Worm gear causes noise
If you hear a grinding sound when you run your mixer, it may be the worm gear. Worm gears are usually made of hard nylon, which makes them less durable than metal gears. The good news is that you can replace your worm gears yourself. To do this, remove four screws, two of which are mounting screws, and the planetary gear. After you remove the worm gear, you can insert a drift punch into the holes on the bottom cover and then lift the center shaft. You can then transfer the worm gear to the upper housing.
If the sound of grinding is still bothering you, then it may be the worm gear in your KitchenAid mixer. It is a plastic gear that is built into the mixer to keep it from burning out. However, if the worm gear becomes damaged, then the motor will fail and will cause a grinding noise. If you’re not confident about your skills, you should consult a technician to fix your KitchenAid.
Height of mixer head causes noise
If you notice that the mixing bowl and the mixer head are not properly aligned, the height of the mixer head may be the cause. To adjust the height, you may turn the mixer head counter-clockwise or clockwise until you find the right position. Make sure the mixer head is level before you start mixing. Keeping in mind that if the mixing bowl is too high, the batter will not get fully mixed. If the mixer head is too low, the batter will get scratched on the bottom. To adjust the height, you should use a screwdriver or small hammer and slightly turn the head clockwise or counter-clockwise to the desired setting.
If the mixing bowl is too high, check the height of the mixer head using a dime. This technique only works with metal-based mixing bowls. Attach the flat beater before using the low-speed stir mode, and use a dime as a guide. If the dime moves half an inch on each pass, the height of the head is correct. If the mixing bowl is too high, the beater attachment will not be able to mix the ingredients evenly at the bottom. The mixing bowl will become scratched and the beater attachment may not properly mix the ingredients evenly.
