F03 and F04 are one fault in KitchenAid's wording: the electronic oven control and its wiring.
Model compatibility: KitchenAid reuses codes across series and model years, so F03 / F04 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
What this code means
Possible problem with the electronic oven control or its wiring.
If your KitchenAid range shows F03 or F04, the support pages point to one part: the electronic oven control, or the wiring connected to it. The two entries are worded the same way.
At a glance
| Code | F03 / F04 |
|---|---|
| What it means | Possible problem with the electronic oven control or its wiring. |
| What you can check | At the breaker panel, turn off the range circuit, wait 60 seconds, and turn it back on. Watch the display for about a minute, then use the oven normally to check it responds. |
| When to call a technician | If F03 or F04 comes back after the reset, a technician needs to look at the control or its wiring. Do not remove the control panel from a powered range. |
Reading the entry
The electronic oven control is the circuitry that turns your settings into oven operation. A possible fault in it or its wiring is the full extent of what KitchenAid says. Because nothing sets F03 apart from F04, treat them as one problem. The wall oven page lists them with identical text.
What KitchenAid suggests
At the breaker panel, turn off the circuit that feeds the range, wait 60 seconds, and turn it on again. When power is restored, watch the display for roughly a minute to learn if the code is shown a second time. If it stays clear, use the oven as you normally would to check that it responds.
Where the advice ends
That single reset is the whole list. A code that comes back after it suggests the control or its wiring needs real attention from a technician, not a screwdriver. Do not remove the control panel from a powered range.
Quick answers
Do F03 and F04 mean different things?
No difference is documented. One sentence is printed for both.
Is oven function mentioned?
No. KitchenAid says nothing about heating while the code displays; the pages only give the reset and an operation check.
Codes to compare
- F06: electronic control and wiring, a close cousin.
- F1-7 / F1-9 / F1-E and related: oven control and wiring only.
- F1E7: the appliance control board is the named part.
