F9Q has no cause on JennAir's page, only the power reset.
Model compatibility: JennAir reuses codes across series and model years, so F9Q 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
JennAir's over-the-range page lists F9Q with reset steps only and does not state a cause.
F9Q is on JennAir’s over-the-range microwave help page, yet the meaning is left out. The entry offers the standard power-reset steps and nothing more: no part, no cause, no symptom.
Reset steps
Cut the power by turning the circuit breaker off for one minute.
Restore it by turning the breaker on.
Keep watching for one minute to check the code stays away and the microwave works.
Reading the result
If F9Q goes away, the page does not explain what it was. If it comes back, all you have learned is that the reset is not enough. Neither result identifies a part.
The minute of monitoring is there to confirm that the code does not appear again and that the microwave works.
Calling a technician
With no cause listed, a technician must diagnose it. Give the full code, F9Q, because F9Q1 is a separate entry that names the touch pad, while F9Q names no part.
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.
