How to Exit the Sabbath Feature
Touch the OFF pad.
If the oven is cooking, wait for a
random delay period of approximately
30 seconds to 1 minute, until only ⊃ is
in the display.
Touch and hold both the BAKE and
BROIL pads, at the same time, until the
display shows SF.
Tap the CLOCK pad until ON or OFF
appears in the display. ON indicates
that the oven will automatically turn
off after 12 hours. OFF indicates that
the oven will not automatically turn
off. See the Special Features section for
an explanation of the 12 Hour Shut-Off
feature.
Touch the START/ON pad.
NOTE: If a power outage occurred while the oven
was in Sabbath, the oven will automatically turn off
and stay off even when the power returns. The oven
control must be reset.
