Over the last couple of months, our KitchenAid microwave/hood combo will randomly beep and the display panel changes by reducing the power to 20%. Once I unplug the unit, it solves the problem momentarily, and then the unit may start acting up again. The microwave still operates properly during this time. The control panel lock key is difficult to lock most of the time. When I can lock the control panel, the microwave may continue to beep half of the time it is locked. Some sites have recommended locking the control panel to tell which part is defective, however, I am not sure in my case. After resetting the circuit breaker, the unit has entered the test mode. Although, I do not get error codes, the test shows that all keys have failed (even though I can successfully press and highlight each Key). Need help in determining which part to replace.
