Maytag Oven F9-E0 error code
F9-E0 means the oven's control detected a problem with the home's electrical supply — possibly miswired outlet or unstable voltage. It can also appear after a power outage or if keys were pressed during power-up.
Also shown as: F9-E0, F9 E0, F9E0, F9

What causes the F9-E0 error?
- Miswired electrical outlet or range connection
- Power outage with line 'noise' the control read as wrong voltage
- Keys pressed within 10 seconds of power-up
- Loose power cord connection at the terminal block
- Tripped or failing breaker delivering unstable power
- Recent electrical work in the home
How to fix Maytag F9-E0 — step by step
Work through these in order, from simplest and safest first. Stop as soon as the code clears.
- Power reset for one minute
Turn the breaker off for one minute, then back on. Wait a full minute without pressing any keys, then check the display. Maytag lists this as the official first step.Safety warning: Do not press any keys for at least 10 seconds after power returns — early key presses can re-trigger the code. - Check the breaker
Make sure the range's breaker is fully on, not sitting in a half-tripped position. Flip it fully off, then fully on.Safety warning: If the breaker trips again immediately, stop and call an electrician. - Think about recent changes
If the range was installed or moved in the last few months, or there was recent electrical work or an outage, tell your electrician — F9-E0 often traces back to the supply, not the range. - Have the outlet checked
If the code keeps returning, Maytag advises having a qualified electrician verify the outlet wiring and voltage. A miswired 240V outlet is dangerous beyond just the error code.Safety warning: Do not test or rewire a 240V outlet yourself unless you are qualified.
When to call a technician
- The code returns after a clean reset with no key presses
- The range was recently installed (likely miswired)
- The breaker trips or you smell burning at the outlet
- Any 240V outlet or wiring work is needed — call an electrician
Frequently asked questions
The code appeared right after a power outage. Is that normal?
Yes. Line noise during an outage can make the control think the voltage is wrong. A clean power reset usually clears it.
Could my range be damaged?
The control flagged the supply before damage occurred — that is the point of the code. But repeated events warrant an electrician's check.
Why should I not press keys right after power-up?
During the first seconds after power returns, the control is calibrating its voltage readings. Key presses in that window can confuse it into showing F9-E0.
