What you came for
On this oven the code E13 reports that preheat ran and the control could not call it successful. The oven usually still heats: what failed is the preheat sequence rather than the heat itself, which is why food can come out fine on a day the code appears. The first cause to rule out is a door opened during preheat, or a cavity that started from a hot state, and it costs nothing to check.
The code and what the manufacturer documents for it
Reference| Code | Documented meaning |
|---|---|
| E13 | The oven did not pre-heat correctly. There may a problem with the Appliance Control Board or the associated wiring. |
What is happening apart from the display
- It reaches temperature on some cycles and not others — Intermittent preheat failures are the usual shape.
- Baking results are inconsistent at the same setting — The cavity is not at the temperature the display claims.
- NEAR MISS - the oven does not heat at all — No heat at all is an element or a supply fault and it is a different page.
What produces this code, likeliest first
- A door opened or a load put in during preheat — Ranked first because it is free to rule out: heat lost during the sequence stretches it past what the control allows, and nothing is broken at all.
- One element out of a pair not pulling its share — Second: half the heat means the sequence never finishes inside its window.
The order to work through it
- Watch the elements through the sequence — One element out of two is visible rather than measurable.
- Feel along the door seal for escaping heat — A tired seal is an owner-visible fault and an inexpensive part.
The owner-side procedure
- Check the door seal and the hinges — A door that no longer pulls up tight loses enough heat to stretch every preheat.
About 10 min
- Power down at the breaker to clear the latched code — So the next attempt reports its own result rather than the last one.
About 5 min
- STOP HERE if the next step is a meter behind the console — Unplug the appliance or switch off its breaker before any panel comes off; a capacitor can hold a charge after the power is off.
What to do before any panel comes off
Safety
Unplug the appliance or switch off its breaker before any panel comes off; a capacitor can hold a charge after the power is off. Everything in the procedure above stays outside the cabinet for that reason. Leave the door switch and the other interlocks exactly as they were fitted - they exist to stop the appliance running when it should not.
When to call a technician
The line is straightforward. Call when an undisturbed preheat still fails, or when the code returns on a cold start: that is an element, a sensing circuit or the control, and the three are separated with a meter. Separately and more urgently: call before relying on it for anything that has to be cooked through. An oven whose preheat the control will not certify is not an oven whose temperature you can trust.

The scope of this reading
Applies to: the model lines that certify preheat before releasing a program. Does not apply to: a specific model's wiring, its part numbers, or its service procedures, all of which vary and none of which are invented here. This page is the general reading of one code; where a more specific page exists for your family or model it is linked from the index below and it is the one to read first.
