What F9Q means
The brand’s guidance for F9Q is a reset, not a named part: power the oven down at the circuit breaker for one minute, then restore it. If the code stays away the oven is fine to use; if it returns, the control is reporting a fault that needs diagnosis.
Error codes
Reference| Code | Meaning |
|---|---|
| F9Q | Power unit down by turning off the circuit breaker(s) for one (1) minute. |
What you observe
- The code appears with the oven idle — Often after a storm, an outage or another appliance tripping on the same panel.
- Keys stop responding — A control that has lost its place may freeze rather than run.
- A cook stops partway — The control drops the function when it hits the fault.
- The clock flashes or has reset — A sign the control saw a power dip.
What usually sets this code
- Control lost its place after a power event — The most common reason, and the one the reset is for: a surge or dip leaves the control in a state it cannot leave alone.
- Recurring control fault — Second: when the code keeps returning, the control or something it monitors is failing, and the reset only clears the display.
- Unstable supply — Third: a loose connection at the breaker, outlet or range terminal block starves the control now and then.
Check in this order
- Do the documented one-minute power-down — It is the brand’s own step and it costs nothing.
- Run what was running when the code appeared — The fair retest is the same function at the same setting.
- Note whether and when it returns — Within minutes points at a real fault; never again points at a power event.
- Check for supply trouble — Tripping breakers, dimming lights or a warm plug move the search to the supply.
Clearing the code, then checking
- One-minute breaker power-down — Switch off the oven’s breaker, or breakers on a double oven, wait one full minute, then switch them back on.
About 2 min
- Retest — Run the function that showed the code at the same setting and watch the display.
About 15 min
- Breaker condition check — Make sure the breaker handles sit firmly on and none feels loose or warm.
Tools: flashlightAbout 3 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.
Safety for this oven
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Ranges and wall ovens are hard-wired or plugged in behind the unit, so the breaker is the safer way to cut power. A range that has been pulled out goes back onto its anti-tip bracket before it is used again. If the breaker feels warm, buzzes or will not stay on, leave it off and call an electrician instead of resetting again.
When to call a technician
Call when the code returns after the one-minute power-down, and especially if it comes back at the same point in the same function. If the breaker itself trips or feels warm, that is an electrician’s call first.

Scope of this reading
The reading above covers Jenn-Air wall ovens and ranges whose electronic control reports codes in this form. It does not cover 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. A model-specific page for F9Q, where one exists, is the more specific answer; none exists yet, so check the use-and-care guide for your exact model before ordering any part.
