Liebherr NoFrost Code Sabbath mode: lights and alarms switched off by design

What Sabbath mode means

On Liebherr US NoFrost units such as the HCB 1560, Sabbath mode is a setup option built to Star-K requirements. You start it in setup mode by holding SuperFrost for 5 seconds. The interior light stays off, and neither door nor temperature alarms sound. After a power failure the unit returns to Sabbath mode on its own, so the observance carries on without anyone touching the controls.

Common causes of Sabbath mode

Sabbath mode switched on deliberately
Sabbath mode started by holding SuperFrost for 5 seconds by accident
The unit resuming Sabbath mode after a power failure

✓ One safe check you can try

1. Open setup mode and look for the Sabbath setting. 2. Hold SuperFrost for 5 seconds in setup mode to leave it. 3. Check that the light and alarms work again. 4. If the mode will not turn off, call us.

! Why to stop there

The mode is a setting, not a problem, so no repair is needed.
If the controls ignore you, the control panel needs a technician.
Alarms are off in this mode, so check food temperature yourself.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Sabbath modeSabbath mode questions

Why is the light off in my HCB 1560?

Check whether Sabbath mode is on. It turns off the light and silences door and temperature alarms. You see no sign that something is wrong, which is why it surprises owners.

How do I leave Sabbath mode?

Go into setup mode and hold SuperFrost for 5 seconds, which is the same gesture that starts it. Then confirm the light and alarms are back.

It went back to Sabbath mode after a power failure. Is that normal?

Yes. The unit is designed to return to Sabbath mode after an outage so the observance continues. Turn it off in setup mode when you want normal operation again.
