Display shows SAB or Sabbath mode; oven does not respond to normal commands.

Safety first: No internal access is required.

• Exit Sabbath mode: On most Zline electronic ranges, press and hold the designated Sabbath mode key combination (often Bake + Timer or similar) for 3–5 seconds until SAB disappears. Refer to the user manual for your exact model.
• Power reset: If the oven will not exit SAB, turn off power at the breaker for 1 minute, then restore and repeat the exit sequence.

When to call a technician: If the control remains stuck in Sabbath mode after following the documented procedure, the control board may be malfunctioning and require replacement.
