The answer first
On a Whirlpool oven, F9Q1 is the control reporting that it could not carry out what it was asked to do, and pointing at the user interface behind the touch pad or the wiring to it.
Error codes
Reference| Code | Meaning |
|---|---|
| F9Q1 | The oven could not execute the function. There may a problem with the User Interface (Touch Pad) or the associated wiring. |
What you observe
- Keys do not respond, respond intermittently, or act on their own — A panel can fail in three directions. Dead, erratic, or reporting a press that never happened.
- The display is lit and otherwise behaves normally — Clock, tones and key presses can all look healthy while one function refuses, because the part that failed is the one that executes rather than the one that displays.
- NEAR MISS — the display is dark and nothing responds at all — That is a supply or main-fuse fault rather than this code, and it belongs on the no-power page.
Ranked causes
- The interface assembly itself has failed — Ranked first because it is the part the documented meaning names, and because it is the part that carries the load or the traffic this code failed on.
- The supply feeding the control is unstable — A shared circuit with a large motor load, a loose neutral or a surge leaves the board browning out mid-operation, which reads as a failure to execute rather than as a power problem.
- Moisture or cleaning product has got behind the panel — Fourth, and worth knowing because it is avoidable. Spray cleaner running down into the panel edge, or steam from the cavity vent, leaves a film that bridges the key matrix.
What to check first, and why
- Power the appliance down completely, then restore it — Not a standby reset — the breaker or the plug, so the board loses its stored state.
- Check what else shares the circuit — A control that browns out repeatedly is often on a circuit with something that starts hard.
- Reseat the ribbons and plugs on the named assembly — With the breaker off and the panel open, each plug is pulled and pushed home.
The steps you can do yourself
- Cut power at the breaker for a full minute, then restore it — A full power-down clears the stored fault and any latched relay state.
About 5 min
- Select the function again and note the exact stopping point — Note which keys work, which do not, and whether the pattern follows a row or a column of the panel.
About 10 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is the line between an owner check and a service call on this circuit.
Before any panel comes off
Safety
Unplug the oven or switch off its breaker before any panel comes off. A capacitor can hold a charge after the power is off, and a built-in oven is normally hard-wired, so the breaker is its only disconnect. If your range burns gas and you smell gas: leave the building without switching anything on or off, call the gas utility or emergency services from outside, and do not look for the leak yourself.
Where the owner checks end
Call if the code survives a full power-down, or if it returns every time you select the function.

What this page does and does not cover
This page reads F9Q1 as Whirlpool documents it for ovens in this range, so it covers the appliance class rather than one model line: a wall oven, a range and a microwave-oven combination can all post it with different hardware behind the panel. Where a family- or model-specific page exists for your unit it is the more specific answer, and it is linked from the code index below.
