F03 and F04 mean the electronic oven control or the wiring to it may be at fault. KitchenAid lists a breaker reset of one minute.
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 the wiring connected to it.
Overview
KitchenAid gives F03 and F04 a shared explanation for wall ovens. Either the electronic oven control or its wiring may have a problem. The control takes in what you set and runs the cooking functions, so the codes are about that brain of the oven and how it is connected, not about a lone heating element or switch.
At a glance
| Code | F03 / F04 |
|---|---|
| What it means | Possible problem with the electronic oven control or the wiring connected to it. |
| What you can check | Turn the oven breaker off, wait sixty seconds and switch it on. Watch the display for the next minute, then use the oven to confirm it works. |
| When to call a technician | If F03 or F04 returns, there is no further owner action, so arrange a service visit. Have the code and a note about the breaker reset ready. |
Reset, step by step
- Turn the oven’s circuit breaker to off.
- Wait sixty seconds.
- Turn the breaker to on.
- Check the display once or twice across the next minute for F03 or F04.
- Use the oven and make sure it works.
Possible results
With the code gone and the oven working, the article asks nothing more of you. If the code is back, it offers no extra owner action, and service is the sensible move. The text does not explain how F03 differs from F04, so neither should be assumed to be the worse one.
FAQ
Does one code outrank the other? No ranking is possible because the wording is identical.
