F9Q1 in brief
F9Q1 means the oven could not carry out the function because of a problem with the touch pad, the key panel you press, or its wiring to the control. If the pad responds normally after a reset the oven can be used; if keys are dead or press themselves, switch it off at the breaker until it is checked.

|---|---|
| F9Q1 | The oven could not execute the function. There may a problem with the User Interface (Touch Pad) or the associated wiring. |
Signs that go with the code
- One or more keys do nothing — A worn membrane or a broken trace in the pad.
- Keys act without being touched — A shorted key or moisture under the pad; the most important symptom to report.
- The function cancels as soon as it starts — The control rejects a key signal it cannot trust.
- NEAR MISS: the display is blank but keys beep — That is the display side of the interface, not the pad.
Causes, most likely first
- Touch pad membrane worn or shorted — The most common cause: years of presses and kitchen heat break traces or fuse layers together.
- Ribbon tail or connector — Second: the pad’s flat cable cracks where it bends, or loosens at the control.
- Moisture under the pad — Third: cleaner or steam that seeps under the overlay makes keys short.
- Control board input — Least likely: the board stops reading the pad correctly.
The order to check, and why
- Dry the panel — Moisture is the cheapest cause to rule out.
- Power-down reset — Clears a control that latched onto a bad key signal.
- Test every key — A pattern of dead keys in one row or column points at the ribbon.
- Let a technician check the connector — The tail plugs in behind the control panel.
Owner steps, with tools and time
- Dry and wipe — Wipe the pad with a barely damp cloth, dry it, and leave the oven off for a few hours if it was recently cleaned.
Tools: microfiber clothAbout 10 min
- Power-down reset — Breaker off for a minute, then on.
About 2 min
- Key map — Press each key once and write down any that fail or repeat.
Tools: notepad or phoneAbout 5 min
- STOP here if the next check needs a panel off — Anything behind a panel is a power-off technician job, and the tests that follow it are made on live circuits.
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. A wall oven is heavy and hangs on its trim and screws; taking it out of the cabinet is a two-person job, not an owner check. If the oven starts a function by itself, switch off its breaker and leave it off until it is repaired.
When this is a service call
Call when keys stay dead after a reset and a dry-out, and at once if keys press themselves, because a pad that starts functions on its own can turn the oven on unattended. Pad and ribbon replacement is a panel-off job on most models.

Generalized information
This is generalized information: it reads F9Q1 the way Jenn-Air documents it for Jenn-Air wall ovens and ranges whose electronic control reports codes in this form. It does not apply to Jenn-Air models with knob-only controls, Jenn-Air cooktops and microwaves, which keep their own code lists, or sister brands built on the same platform, whose lists can read differently. No model-specific page for F9Q1 exists yet; when one does, it is the more specific answer for that model line.
