KitchenAid Stand Mixer Not Working – Will Not Turn On – Beater Hits Bowl

How to fix your KitchenAid Stand Mixer. If you are having problems with your KitchenAid stand mixer, here are some ways to troubleshoot the issue and repair it yourself. The beater attachment and the bowl need to be connected properly for the unit to operate. If the beater blades hit and vibrate the bottom of the bowl or side of the bowl they will need to be readjusted. When your mixer will not start, you may have a motor that has overheated as the mixer motor is thermally protected. An electrical issue such as a reset GFCI outlet or electrical breaker may also be causing the problem. Here is a KitchenAid Stand Mixer Troubleshooting page if you need further assistance.

KitchenAid Stand Mixer Will Not Turn On

Check that the mixer is plugged in. If the outlet the mixer is plugged into is GFCI, check to be sure it is not reset. If the mixer is plugged in and the GFCI is not reset, check the breaker for that outlet.

If you determine the mixer is getting power, the issue may be the cord on the mixer is damaged or an internal part inside is faulty. The speed control plate could be faulty, the mixer phase control board may be bad, you may have worn carbon motor brushes, or the wiring inside the mixer could be damaged.

If needed take the mixer apart and check the parts and components we have listed.

NOTE: The motor on your KitchenAid mixer is thermally protected. If it overheats, the motor will temporarily shut down for safety reasons. Wait around 15 to 30 minutes if you suspect this has happened.

Check the adjustment of the bowl clearance. To raise or lower the bowl, turn the flat head screw that is located under the head portion of the mixer. Turn the screw clockwise to lower it and counterclockwise to raise the bowl.

Also adjust the height of the mixing bowl so the beater will not hit the bottom or the sides of the bowl.

If the pivot pin is not centered and secured, try centering the pin. Turn the mixer onto its side and tighten the screw underneath the mixer to secure the pivot pin.

  1. I have a 2018 5qt Artisan mixer that stopped turning. We replaced a gear and gasket and it now turns, but isn’t powerful enough to mix a 5cup flour bread dough. What else could be the problem?

  2. I have a KitchenAid mixer artisan series with the glass bowl. I can hear the motor running but the mixer doesn’t work. We replaced the worm gear and it was broken. When we plugged it back in (without any attachments or bowl) it started to run for a second and then broke again. What needs to be fixed that keeps breaking the worm gear?

    Most likely your KitchenAid Mixer either has a faulty wired ON/OFF switch, a fried ON/OFF switch, or the motor is wired incorrectly.
    Can you give us the model number of your KA mixer?
    We will find you a wiring schematic diagram to assist you in rewiring it or finding the correct parts to remove and replace and get it running.

  4. I found a Kitchen Aid mixer thrown away outside a rubbish store. I took it home plugged it in but it would not work. I took the back cover off and checked for power and there’s power even when it is turned off. There is power to the two cables that lead to the motor, could it be a reset button?

  5. Gary, I have exactly the same problem. Did you ever figure out what was the problem with the mixer not being able to be powered on. I did the same thing – replaced the worm gear (that was damaged) and then when I went to turn it on – nothing.

  6. Hi. I have a Kitchenaid stand mixer. It worked fine. I went to use it again and the speed control lever was bent and would not move. I bent it back and it was able to move. But, when I plugged in the unit and turned it on, nothing happens. I opened the back and the lever still moves the speed control plate. So, I cannot figure out what the issue is.

    Any ideas?

  7. Same here (minus the pin). There is power, as I got a small shock touching the wire connection, but nothing when I turn it on. Did you ever find a solution?

  8. I took my mixer head apart to give it that extra deep clean and now it won’t turn on. I do however have a 2 1/2 – 3 inch pin left over lol. It looks like a large watchband pin and i believe it must be the safety pin of some sort. I would appreciate any help you could give me.
    Thanks in advance.

  9. KItchenAid K5SS mixer. Using it… worked fine. Then turned back on and stopped working. Motor is not working as if no power but plug and all are fine. Flicking switch off and on several times there is a short burst of motor engagement then stops. Checked brushes… look good. Dusted off parts inside the back housing… no difference.

  10. My KitchenAid Artisan stopped working. When turned on it made no sound whatsoever. I found nothing on YouTube with my specific condition, so I guessed it was the KitchenAid Mixer Phase Control Board and bought a new one. Though the mixer still did not work after replacing the phase control board, I’ll never know if that was the problem because, for whatever reason, I removed the brushes to clean them and obviously put them back in wrong. I bought and replaced the speed control plate and the governor assembly (the governor assembly since I already had the unit apart). The unit still did not work. I rearranged the brushes and the unit now works just fine. Thank you kindly!

  11. I just did the same repair for the third time over the life of the mixer and this is the first time it would not turn on afterwards. The brushes are both at 15 cm, which doesnt seem to be too worn and it worked before the worm gear change just fine. My mixer is over 20 years old and it has square to put the brushes into, there is no notch or cut out, etc… so you CAN position them wrong as opposed to what I’m reading everywhere. Is there a standard position for them?

  12. I replaced the plastic worm gear. I tried the mixer before replacing and it would run but not the planetary gear. When I disassembled the head, the worm gear was worn. I replaced the worm gear and reassembled the mixer. When I turned on the mixer, it wouldn’t turn on. I checked the incoming voltage to the speed control plate and had 120V to the motor. I cleaned the contacts to the disconnector at the bottom of the speed control plate and had 120V to the other side of the contactor bar. I checked voltages to the wire connectors on the speed control plate for the phase control board and didn’t get any type of voltages through out the speed switch manipulation. I can’t understand why the motor would run before the repair then all of a sudden something in the control circuit would go bad. What is the most likely problem before having to swap until I drop?

  13. My kitchen aid stand mixer is leaving a brown oily liquid under it. When you turn it over you can’t see where the liquid is coming from. The mixer works well although I don’t think the beater scrapes the sides very well.

  14. My mixer might have a short ? Sometimes it won’t turn on , but sometimes if I stop it to scrape the bowl, it won’t turn back on .. you have to move the lever back and forth until it finally turns back on

  15. I have a KitchenAid Professional 600 mixer.
    When I turn it on the low speed, it starts and then goes to high speed and runs high for approx. 3 seconds and then cuts out. (Turns off).
