5Ab in brief
5Ab on the display means Sabbath Mode is enabled, not that something has failed. In Sabbath Mode the oven stays on in a Bake setting until it is turned off, so it will not time out the way it normally would; switch the mode off with the sequence in your model’s use-and-care guide, and the oven returns to normal operation.
Error codes
Reference| Code | Meaning |
|---|---|
| 5Ab | The Sabbath Mode is enabled. Sabbath Mode sets the oven to remain on in a Bake setting until turned off. |
Signs that go with the code
- The oven stays on in Bake without timing out — That is what Sabbath Mode is designed to do.
- Keys seem to be ignored — Sabbath Mode limits what the keys can change.
- Tones and prompts are silent — The mode suppresses them.
- NEAR MISS: the oven will not heat at all — That is not Sabbath Mode; a cold oven with this display needs a different explanation.
Causes, most likely first
- Sabbath Mode switched on on purpose — The most common reason: someone enabled it for a holiday or the weekly Sabbath and it was not switched off.
- Mode entered by accident — Second: a long press while cleaning the panel or setting the clock can enter it on some models.
- A key acting by itself — Least likely: if the mode keeps coming back with nobody touching the oven, a faulty key may be entering it.
The order to check, and why
- Confirm the oven is holding a bake — That confirms the mode rather than a fault.
- Use the exit sequence for your model — The use-and-care guide gives it; it differs between models.
- Ask who last used the oven — Often the quickest answer.
- Watch whether it comes back by itself — If it does, the keypad is suspect.
Owner steps, with tools and time
- Exit Sabbath Mode — Follow the exit sequence in your model’s use-and-care guide; on many models it is a press-and-hold of the key that entered it.
Tools: use-and-care guideAbout 5 min
- Check the oven is back to normal — Set a short bake and confirm that tones, prompts and the timer work again.
About 10 min
- Power-down reset if it will not exit — Switch off the breaker for a minute; on some models the mode resumes after power returns, so the exit sequence is still the main route.
About 2 min
- STOP here if the next check needs a panel off — Anything behind a panel is a power-off technician job, and the tests that follow it are made on live circuits.
Before you open anything
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 wall oven is heavy and hangs on its trim and screws; taking it out of the cabinet is a two-person job, not an owner check.
When this is a service call
Call only if the mode will not switch off with the exit sequence, or keeps turning itself on with nobody touching the oven. A mode that enters by itself points at a keypad fault, which is a technician job.

Generalized information
This is generalized information: it reads 5Ab the way Amana documents it for Amana ranges and wall ovens whose electronic control reports codes in this form. It does not apply to Amana models with knob-only controls, Amana cooktops sold as separate units, which keep their own list, or sister brands on the same platform, whose lists can read differently. No model-specific page for 5Ab exists yet; when one does, it is the more specific answer for that model line.
