The short answer
5Ab is a report, not a diagnosis: it says Sabbath Mode is running, which is a setting the oven was put into deliberately. Nothing is wrong with the appliance: while the mode is on the oven stays in its bake setting and the usual tones and display changes are suppressed, which is the whole point of it.
The documented code reading
Reference| Code | Documented meaning |
|---|---|
| 5Ab | The Sabbath Mode is enabled. Sabbath Mode sets the oven to remain on in a Bake setting until turned off. |
Symptoms that travel with this code
- The display shows the mode instead of the usual readout — Which is what brought you here.
- Tones, the light and display changes are suppressed — Suppressing them is why the mode exists.
- NEAR MISS - the oven is unresponsive and the display shows something else — A control lock or a fault code is a different page; this one is a mode.
What produces this code, likeliest first
- The mode was switched on, deliberately or by accident — Ranked first because it is the only cause: this display is a setting, and something in the console sequence switched it on.
- A keypad press held long enough to enter it — Second: the sequence is often a held press, which is easy to do while cleaning the console.
The cheapest checks first
- Confirm it is the mode and not a lock or a code — Free, and it decides which instructions apply.
- Try switching the oven off completely — On many model lines that is enough to leave the mode.
What you can do without tools
- Switch the oven off and see whether the display returns to normal — The simplest exit, and it works on many model lines.
About 5 min
- Use the exit sequence from the manual for your model — The sequence is model-specific.
About 10 min
- STOP HERE - there is nothing to dismantle — This is a setting.
What to do before any panel comes off
Safety
Unplug the appliance or switch off its breaker before removing any panel - a capacitor can hold a charge after the power is off. Leave every switch and interlock wired as the manufacturer fitted it: they are what stops the appliance running in a state it should not. If the plug, the cord or the outlet is discoloured or hot, stop there and have the supply looked at before the appliance.
The point at which you call
Call only if the oven will not leave the mode using the sequence in its own manual: then the console is not responding properly and that is a service matter rather than a setting. One exception to the order above, because it is about safety rather than cost: no hazard in the mode itself.

How far this page applies
This page is the appliance-class reading of one code, for the model lines that offer this mode, which is not every oven. It stops short of model-specific figures on purpose: those differ by family, and a plausible-looking wrong number is worse than none. If your model has a page of its own it is the more specific answer and is linked from the code index below; use this page as the general orientation.
