Samsung Range bAd LinE / Bad Line Error Code

Samsung directs readers to the installation manual or a professional installer for bAd LinE. This is an installation and electrical-connection issue, not a homeowner internal-wiring task.

Applies to Samsung range or wall oven

What the appliance detected

Detected condition

The power connection is not connected properly.

What may contribute

Possible causes

  • An improper power connection, as described by Samsung.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the display and model

    • Photograph or write down bAd LinE or Bad Line and confirm the exact model number.
    • Locate the installation manual without removing panels or pulling the appliance away from the wall.

  2. Stop use and contact an installer

    • Do not use the oven or cooktop while the power connection is in question.
    • Refer the installation manual and appliance to a professional installer or qualified electrician.

  3. Leave the appliance de-energized

    • If the electrical panel is safely accessible and there is no fire or wet-electrical hazard, switch off the appliance circuit breaker and leave it off.
    • Do not apply the general Samsung reset sequence to an improper power-connection condition.

Actions not recommended

  • Do not open the outlet, junction box, terminal block, power connection, or appliance panels.
  • Do not perform live-voltage, continuity, or other electrical tests.
  • Do not reconnect internal wiring or repeatedly restore power to see whether the message clears.

When to stop and request service

  • Use a professional installer or qualified electrician whenever bAd LinE appears.
  • Keep the appliance off until the connection has been evaluated and corrected.
  • Seek urgent help for smoke, sparking, a burning smell, uncontrolled heating, visible wiring damage, repeated breaker trips, or abnormal heat.
