The short answer
E03 comes from the panel rather than from the cavity. E03 is a user-interface fault: the keypad or user interface, or its wiring has reported a problem to the control, or has stopped answering it. The oven will usually refuse input until it clears.
This code and its neighbours on this appliance
Reference| Code | Meaning |
|---|---|
| E03 | The Keypad (User Interface) reported a problem to the control board. There may be a problem with the Keypad (User Interface) or the associated wiring. |
| F2 | The Keypad (User Interface) reported a problem to the control board. There may be a problem with the Keypad (User Interface) or the associated wiring. |
| E11 | The Gas Sensor reported a problem to the control board. There may be a problem with the Gas Sensor or the associated wiring. |
What you see alongside the code
- One key does nothing while the others work — A membrane trace that has failed under that key, which is the most localised version of this fault.
- The oven behaves as though a button is held down — A key stuck closed sends a continuous press, and the control eventually reports it.
- NEAR MISS - the panel is dead and the display is dark — No display at all is a supply or control fault, not an interface one.
What triggers it, most likely first
- Debris or residue holding a key closed — Ranked first because it is the most common and the only one an owner can fix.
- Moisture behind the panel — Steam from the cavity or liquid from cleaning tracks under the overlay and bridges the traces.
- A failed membrane or printed trace — The keys are printed conductors and they wear at the most-used positions.
Check in this order, and why
- Press each key in turn and note which respond — One dead key among working ones and a whole dead panel are different repairs, and this costs nothing to establish.
- Look closely at the key edges for residue — A key that sits slightly proud of its neighbours is holding a press.
- Cut power for several minutes and restore — Clears a transient and tests whether the fault condition is continuously present.
The owner-safe procedure
- Wipe the panel and the key edges with a barely damp cloth — Barely damp, never wet, and never a spray aimed at the panel.
Tools: clothAbout 10 min
- Press every key once and write down which respond — This list is the diagnosis. Bring it to the visit rather than a description.
About 8 min
- Switch off at the breaker for several minutes, then restore — If the code returns instantly a key is stuck closed; if it takes a while it is something else.

Safety
Unplug the appliance or switch off its breaker before removing any panel - a capacitor can hold a charge after the power is off. Never spray a cleaner directly at the control panel: it runs behind the overlay by capillary action and causes exactly this fault. Do not use a blade or a tool to free a stuck key.
When this is a service call
Call when cleaning and a clean reset leave the code standing, or when a key is dead while its neighbours work. Both point at the membrane or the ribbon, behind a housing that carries live terminals. Call immediately if the panel is unresponsive and the oven has started a cycle you cannot cancel.

What this page does not cover
Read this as generalized information. It is written for E03 as the KitchenAid oven code list documents it across the brand rather than for one family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer and is linked from the code index for this appliance. Some of the codes listed beside it in the table above carry the same documented meaning on this platform and some are documented differently, so check the characters on your display carefully before acting on this page.
