Clear the settings before suspecting the board
Look for a lock symbol, a timer or delay indication, and a clock that is flashing or unset. Clear whatever you find, then try the oven again. If it still refuses, a temperature sensor reading out of range is the next candidate, and the board is the one after that.
What the oven does
- The console lights and beeps but the oven will not heat — Awake and refusing, which is the settings case rather than a failure.
- A lock, timer or delay indicator is showing — A deliberate feature. It is meant to look like this and it is cleared from the panel.
- The clock is flashing or shows no time — On some cabinets the oven will not run until the clock has been set.
- A code appears after the oven has been hot for a while — More likely a sensed condition or heat reaching the control than a control failure.
- The oven runs but the temperature is far from the setting — A sensor or calibration question rather than a control one, and a different investigation.
- NEAR MISS: the display is dark and nothing beeps — That is a supply question and belongs on the will-not-start page.
Ranked for this console
- A timed bake or delay left programmed — First, because it is easy to set by accident while adjusting the timer, and because it produces a console that responds to everything except the request to heat.
- Control lock engaged — Second. A long press on a marked pad sets it, and it is commonly triggered while wiping the console.
- The oven temperature sensor out of range — Third. It makes the control refuse or stop calling for heat, and it is the first genuine fault on this list.
- The control board — Last. It is blamed constantly and is rarely the cause, and none of the three above cost anything to eliminate.
Settings, then sensing
- Read every symbol on the console and write down what is lit — Many of these complaints are solved at this step, and it costs a minute.
- Cancel any timer, delay or timed bake — Cancelling usually needs a specific pad; switching the oven off does not always clear a programme.
- Clear a lock indicator with the marked pad — Second cause, and equally quick.
- Set the clock if it is flashing, then try again — On some cabinets that is genuinely a precondition for the oven running at all.
Owner steps
- Photograph the console exactly as it is before pressing anything — Indications disappear as soon as you start clearing them, and you may want them later.
Tools: phoneAbout 5 min
- Press cancel or clear and then try a simple bake setting — It removes any programme without changing anything else.
About 5 min
- Hold the pad marked with a lock symbol for several seconds — The indicator clears and the console starts accepting settings again.
About 5 min
- Set the clock, then cut power at the breaker for a minute and try once more — A cold restart after clearing settings separates a stored refusal from a live one.
About 15 min
- STOP before the console or the rear panel comes off — Behind both is live supply on a heavy circuit, and that is the boundary.
Before anything is opened
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. A range may be held by an anti-tip bracket and a wall oven is supported by its cabinet, so neither should be pulled out alone. Leave the door lock as the factory fitted it, because on a self-cleaning oven it is a thermal safety device rather than a convenience.
When it becomes a call
Call once every setting is cleared, the clock is set and the oven still refuses, because the sensor and the control are then genuinely in question. Call the same day if the oven will not switch off, if the door stays locked with the cavity hot, or if anything smells of burning. An oven that cannot stop heating is a different category of fault from one that will not start.

What this page does not carry
Written for the GE oven class rather than one console generation. Which pads carry the lock and the timer, and whether your cabinet requires a set clock, differ by family and belong on the page for your model. That page is the more specific answer where it exists.
