The Kitchenaid Mixer has certain built-in precautions to prevent users from damaging the components inside. When it gets too hot or is assembled improperly, it will not work. Heavy use can also cause the mixer to malfunction. Certain parts of the mixer heat up during use, and may become overheated. Fixing a Kitchenaid Mixer that won't turn on may be a simple procedure, or you may have to send it back to the company's Service Center for repair.
Check to make sure the Kitchenaid Mixer is firmly plugged into an outlet and that the cord is not twisted, dented or split.
Look at your circuit breaker box in your home to make sure the Kitchenaid Mixer's outlet has power. An alternative is to plug in another appliance and see if it works.
Unplug the mixer for 10 to 15 seconds and then plug it back in. If this is unsuccessful, unplug the mixer for 30 minutes to cool it off and then try plugging it back in and using it.
