KitchenAid Power Supply Instability / Control Reset

Microwave clock loses time, resets randomly, or the unit restarts by itself.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Loose power cord connection, failing noise filter board, failing main control board power supply, intermittent house power or shared circuit overload

Safety: Unplug the microwave before accessing internal components.

Check outlet and plug: Ensure the plug fits snugly in the outlet and the outlet is not loose.
Dedicated circuit: Move the microwave to a dedicated circuit if it currently shares with other heavy loads.
Inspect noise filter: Access the noise filter board and check for loose connections or burnt components.
Replace control: If the power supply section of the main control is unstable, replace the main control board.
