KitchenAid Over-the-Range Microwave Code F9Q: Reset power and watch for a minute

What F9Q means

On KitchenAid over-the-range microwave hood combinations such as the KMLS311HSS or KHMS155LSS, F9Q is handled by a power reset. After the reset, watch the microwave for one minute to confirm the code does not come back, then verify normal operation. If it repeats, the unit needs a technician to look at the control. You do not need tools or any special knowledge for the first step.
