How to Fix Your KitchenAid Mixer Without Hiring a Pro

There’s no question about the magical efficiency of your Kitchen-Aid mixer. It helps reduce the workload when preparing your favorite foods or kneading your bread dough. However, what if went to use your mixer and it stopped working properly or wouldn’t even turn on? Calling a technician or taking it to your local service center could be time consuming, not to mention costly! Not to fret, we’ve got you covered. Here’s how to fix your KitchenAid mixer yourself, without hiring a pro.

3 Most Likely KitchenAid Mixer Issues

The common problems you will face with your mixer are:

  • The machine won’t turn on.
  • The beaters are hitting the bottom of the bowl.
  • There’s a worm gear break inside the device.

That doesn’t mean that there aren’t any other issues that could occur, they are just the most common problems. Some other issues might be, leaking, locking (opening or closing), and some users have complained of sluggish mixture when trying to whip cream.

However, you’ll be glad to know that these are rarely seen, unlike the first three.

The Machine is Not Turning On

If your machine is not turning on, this could be due to an electrical issue with the electrical breaker or the GFCI outlet.

If that is the case, you can try the below tips:

  • 1
    Check if the mixer is plugged in properly. If the outlet is GFCI, then you have to look to see if it needs to be reset. If both things are normal, now you'll need to check the circuit breaker of the outlet.
  • 2
    If you are sure that the power supply is okay, then the power cord may be damaged. If so, then you have to replace it with a new one without taking a risk of repairing it temporarily.
  • 3
    If all the above-mentioned issues are perfectly alright, then your machine has certainly occurred some fault from inside. There are three points that could be the reason. These are; the speed control plate, the mixer phase control board, and the carbon motor brushes. Apart from that, the wiring inside the motor could also be damaged to create this problem. In all three cases, if you're not an expert electrician, it would be better for you to call an expert to save your machine from further damage.

The Beaters are Hitting the Bottom of the Bowl

If the beaters of your Kitchenaid mixer hit the bottom of the bowl or it's not mixing properly, then it’s your machine's fault. It just means that you need to do a small adjustment with your mixer.

The mixer should be adjusted in a way that the beaters are closer to the bowl, without coming into contact with the bottom or the sides of the bowl. Now it’s time to look at the way to fix this issue.

With the two types of Kitchenaid mixers, your adjustments should be:

Tilt-Head Models: You will need to unplug the mixer first and then tilt the head up to find the screw. A slight clockwise turn will allow the beater to get lower and the anti-clockwise turn will make the beater higher.

Bowl-Lift Models: After unplugging the machine, you need to place the bowl lift handle to the downward to find the screw. After that, you have to turn the screw gently to the right for lower adjustment and to the left to raise the beater.

Worm Gears

Repairing the Broken Worm-Gear

A worm-gear is one of the parts of your mixer that will need to be repaired quite often, as it has the tendency to break down rather than other parts throughout the life of your device.

As a result, your machine will not either spin properly or completely. Especially for bakers who use it for making thick heavy bread dough. These users will face this problem at least once or twice in the mixer’s lifetime.
