Samsung Range Error Code bAd LinE

The bAd LinE error means the range has detected that the power cord is not connected correctly at the terminal block on the back of the unit. The L1, L2, and N (neutral) wires must each be connected to their specific labeled terminals for the range to operate safely. This error is a protective measure that prevents the range from running when the incoming power configuration is incorrect. It does not indicate a failed component but rather a wiring problem that needs to be corrected.

Yes, incorrect power cord wiring is a genuine safety concern because it means the range is receiving power in an unintended configuration. Samsung's control system displays this error specifically to prevent operation under these conditions. You should not attempt to bypass the error or continue using the range until the wiring at the terminal block has been inspected and corrected. If you are not comfortable working with 240-volt wiring, contact a qualified electrician or appliance technician.

If the problem is simply a wiring mistake at the terminal block, there is no parts cost since no components need to be replaced. If you hire a technician to inspect and correct the wiring, you can expect to pay somewhere in the range of $75 to $150 for a service call, depending on your location. If the power cord itself is damaged or the wrong type and needs replacement, power cords for ranges typically cost between $15 and $40 for the part alone.

Start by disconnecting power to the range at the circuit breaker. Remove the cover plate on the terminal block at the rear of the range and inspect where each wire from the power cord is connected. Compare the current wiring to the diagram on the appliance label and move any wires that are on the wrong terminals to their correct positions. Tighten all terminal screws securely, replace the cover, restore power, and check whether the error has cleared.

A simple reset will not permanently clear the bAd LinE error because the control board checks the power line connections each time the unit is powered on. The error will return immediately if the wiring at the terminal block is still incorrect. The only way to resolve it is to correct the L1, L2, and N connections at the terminal block before restoring power.
