KitchenAid Stand Mixer Won't Turn On: Reset Button and... | appliancefaults.com

Technical Background:

The KitchenAid stand mixer utilizes a simple control circuit. The AC power enters the mixer, goes through an on/off switch, a speed control, and the motor. A reset button (overload protector) and fuse are placed in series to protect the motor from overcurrent conditions. A failed component or overload will trip the reset button or blow the fuse, cutting power to the motor.

Symptoms:

The KitchenAid stand mixer is completely dead. No lights, no motor sound, nothing happens when the power switch is turned on. The user has already tried pressing the reset button on the bottom, but it did not solve the problem. The user suspects a blown fuse.

Possible Causes:

Overload tripped reset button.
Blown internal fuse.
Faulty motor windings.
Defective speed control board.
Damaged power cord.
Loose wiring connection.

Solution:

1

Unplug the mixer from the outlet.
2

Locate the reset button on the bottom of the mixer. Press the reset button firmly.
3

Plug the mixer back into the outlet and test.
4

If it still fails, unplug the mixer. Open the access panel (usually on the bottom). Use a 1/4-inch nut driver.
5

Locate the internal fuse. Check the fuse for continuity using a multimeter. If it reads open, replace with the same amperage fuse.
6

Inspect the power cord for damage. Use a multimeter to check continuity of the cord.
7

If the fuse blows immediately after replacement, the motor or speed control board may be faulty. Further diagnosis required.

Safety Warning:

Always unplug the mixer before performing any repairs. The appliance contains 120V AC, which can cause serious injury or death. Use Lock Out Tag Out procedures. Wear safety glasses.

Prevention:

Avoid overloading the mixer with heavy dough or prolonged use. Follow the manufacturer's guidelines for maximum batch sizes. Clean the mixer regularly to prevent ingredient buildup that could strain the motor.

Expert Tip:

Some KitchenAid mixers have a thermal overload cutout wired internally to the motor windings. This cutout can fail open, preventing the motor from running. These are not easily replaced and typically require motor replacement.

Frequently Asked Questions

•How do I find the correct replacement fuse?

The fuse amperage rating is usually printed directly on the fuse itself. It may also be listed in the mixer's service manual or on a label inside the mixer's housing.

•How do I test the motor windings for shorts?

Using a multimeter set to ohms, measure the resistance between each motor winding terminal and the motor casing. A low resistance (close to 0 ohms) indicates a short to ground.

•Where can I find a wiring diagram for my KitchenAid mixer model?

Wiring diagrams are often included in the service manual. Search online for the service manual for your specific KitchenAid model number. Some appliance parts suppliers may also provide wiring diagrams.
