Error codeF9

What F9 points to
On an over-the-range Maytag microwave, F9 means the requested function could not be completed. Three areas are named: the appliance control board, the relay control board, and the wiring that goes with them.
Try this at the breaker
First, cut power at the circuit breaker for one minute.
Restore power at the breaker.
Stay near the display for a minute and see if F9 reappears.
Last, make sure the microwave operates.
Still showing F9
Control boards and wiring are not owner repairs. If the reset leaves F9 in place, the next step is a technician visit.
When F9 will not clear, Maytag microwave repair in San Francisco and the surrounding Bay Area starts with a call to (415) 649-2156. Keep the model number handy and say that you already ran the breaker reset.
Model compatibility: Maytag reuses codes across series and model years, so F9 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
F9 may point to a fault in the appliance control board, the relay control board or the associated wiring, and the function could not be completed.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
