If your mixer isn't turning on, there could be several issues with it. First, check the circuit breaker in your home to make sure power is supplied to the mixer. Unplug your mixer and wait 15 seconds to plug it back in. If this does not work, there could be an issue with your phase board. See the guide on how to replace the KitchenAid mixer phase board.
