Common culprits

Mixer issues that manifest as a single speed can have various underlying causes:

Possible mechanical issues

• Worn or damaged speed control mechanism
• Malfunctioning internal gears
• Jammed components that are affecting speed adjustments

Possible electrical problems

• Faulty wiring or loose connections inside
• Damaged power cord or plug
• Issues with the motor or its components

Control board malfunction

• Internal issues can lead to incorrect speed settings
• Circuitry issues may be affecting the speed control function

Safety precautions

Always remember to keep safety first when working on your KitchenAid stand mixer to prevent accidents or damage to the appliance.

• Unplug the mixer from the electrical outlet to eliminate the risk of electric shock.
• Make sure you have good lighting so you can clearly see the mixer’s components.
• Clear your workspace of clutter and other obstacles.
• Never work on your mixer with wet hands. Make sure the work area is completely dry.
• Follow the manufacturer instructions included in your mixer’s user manual while troubleshooting.
• Handle all mixer parts carefully and avoid touching exposed wires.
• If the mixer has recently been used, give it plenty of time to cool down before working on it.
• Take your time and don’t rush while working to prevent accidents and personal injuries.
• Keep children and pets away from the work area while you’re troubleshooting the mixer.

What you need

• Multimeter – for checking electrical continuity and voltage
• Flathead and Phillips-head screwdrivers – to access and disassemble parts
• Needle-nose pliers – for gripping and maneuvering small parts and wires
• Socket wrenches set – if needed, make sure you have the appropriate sizes
• Electrical tape – to insulate and secure wires
• Protective gloves – to prevent injury and keep your hands clean

Troubleshooting steps

1. Disconnect the mixer from the power outlet.
2. Check the speed control lever for any visible damage or obstructions. Make sure it moves freely and isn’t stuck in one position. If you need to replace it, scroll down to the next section.
3. Look over the power cord, plug, and any wires inside the mixer for signs of damage, fraying, or loose connections. If you find any damaged wires, replace them with a new OEM wiring harness.
4. Open the mixer’s housing and inspect the control board for burnt or damaged components, loose wires, or signs of overheating. If you notice any issues, replace it.
5. Use a multimeter to test the motor’s continuity and, if you’re comfortable doing so, its voltage. See if it receives power when you adjust the speed control lever. A voltage test requires the mixer to be plugged in, so please take extreme caution to protect yourself from electric shock, which has the potential to cause serious injury. If the motor is receiving proper voltage and is malfunctioning, it may need to be replaced. If the motor is not receiving voltage, the speed control may need to be replaced.
6. When installing any replacement parts, make sure they’re placed correctly and securely.
7. Carefully reassemble the mixer by following the user manual’s instructions in reverse order.
8. Plug the mixer back in and test it at various speed settings to see if the issue is resolved.

How to replace a faulty speed control lever

If you need to swap out your mixer’s speed control lever, follow these steps – along with your mixer’s user manual instructions – to do so:

1. Disconnect the mixer from the electrical outlet.
2. Remove the mixer head and locate the speed control lever.
3. Depending on your mixer model, the lever can be held in place by a screw or a retaining clip. Remove these fasteners.
4. Carefully detach the old lever.
5. Align the new speed control lever in the correct position and secure it with the screw or retaining clip.
6. Reassemble the mixer, plug it back in, and test it at various speeds.

Mixer maintenance tips

• Always follow the manufacturer’s recommendations for using the speed settings.
• Avoid overloading the mixer, which can strain the motor.
• After each use, clean the mixer’s attachments, mixing bowl, and exterior. Use warm, soapy water and a soft cloth or sponge to remove any food residues or splatters.
• Never immerse the mixer in water. Only wipe it down with a damp cloth.
• Periodically lubricate the mixer’s moving parts to keep them operating smoothly. Refer to your mixer’s user manual for specific lubrication points and any recommended lubricants.
• Clean and inspect attachments regularly for wear or damage. Replace any attachments that show signs of wear to keep your mixer working correctly and prevent strain on the motor.
• Check for loose screws or fasteners in and around the mixer. Gently tighten any loose components to prevent excess vibration or other issues during operation.
• Regularly inspect the power cord and plug for any damage. If you notice fraying or exposed wires on the cord, discontinue using it immediately and replace it with a new one.
• When not in use, store your KitchenAid mixer in a clean and dry location. If possible, cover it with a mixer cover to protect it from dust and moisture.
