The short answer
F9Q is documented with an instruction rather than a named part. The manufacturer's entry says to switch the oven off at the breaker for around a minute and restore it, which tells you the code is treated as a state the control could not get out of by itself. If it comes back after a proper power-down, it is no longer transient and the next step is a technician rather than another reset.

| F9Q | Power unit down by turning off the circuit breaker(s) for one (1) minute. |
What you observe, and what to record
- The code appears and the display stops responding usefully — A latched state holds until power is removed, which is what the documented remedy is for.
- Whether the display shows anything besides the code — A second code, a flashing indicator or a missing segment is information the code number alone does not carry.
- Whether the ${A} still does everything else it should — What still works narrows the search as effectively as what does not, and it is the question a technician asks first.
Causes, most likely first on this oven
- A board that has latched a fault it can no longer clear — First: the remedy is documented precisely because this is what the code usually is — a held state, not damage.
- A supply event at the outlet or the breaker — Second, and it is why the documented reset is at the breaker rather than at the panel: the point is to remove power, not to restart the software.
- A loose or heat-cycled connector — Third: intermittent contact is the mechanism behind a code that comes back on a schedule of its own.
Check in this order, and why
- Do the reset properly, at the breaker — Cutting power at the breaker is not the same as switching the appliance off at its panel, and only the first removes power from the board.
- Count how long it stays away — Minutes, days or weeks — that interval is the most useful thing an owner can record.
- Note what else is on the circuit — A repeat code on a circuit shared with a heavy motor load is worth mentioning.
What an owner can safely check
- Switch the breaker off for about a minute — switch the oven off at its breaker. A minute is long enough for the boards to lose their stored state.
About 5 min
- Clear the area around the ${A} before anyone visits — Access is charged for like anything else, and a technician who cannot reach the back of the appliance cannot test it.
About 15 min
- Find the manual, or download it for your model number — Model-line documentation frequently says something the general code index does not.
About 10 min
- STOP HERE — do not reset repeatedly — Cycling power at a fault that keeps returning tells you nothing new and stresses the supply side.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Let the cavity cool completely first: the racks, the door glass and the trim all hold heat for far longer than the display suggests, and the lock will not release above its own threshold anyway.
When to call a technician
Call once the code returns after a proper breaker reset, and call rather than repeat the cycle if it now returns within minutes. A technician will want the interval between returns, what else shares the circuit, and what the oven was doing each time — collect those and the visit is much shorter.

What this page does not cover
This page reads F9Q for KitchenAid ovens in general, from the manufacturer's shared code index. A code can be documented differently for one family, so where a model-line page exists for your unit it is the more specific answer and is linked below. Not here: wiring colours, connector positions and part numbers, which differ by family.
