What Line Error means on a Samsung range

The Line Error code on a Samsung range indicates that the appliance is not receiving proper power from the supply circuit. Specifically, the range has detected that the power supply cable is incorrectly installed or that the wiring at the terminal block or wall connection is improperly configured. This is a supply-side electrical fault, meaning the issue originates before the range's internal components and typically involves the connection between the home's electrical system and the appliance itself.

Samsung ranges require a correctly wired 240-volt circuit with the neutral and hot legs connected precisely as specified for the unit's configuration, whether the range is set up for a 3-wire or 4-wire connection. An incorrect wiring arrangement, a loose terminal connection, a reversed wire, or a missing neutral can all trigger this error. The range detects the anomaly during its power-on self-check and displays the Line Error message to alert the user before any cooking functions are attempted.

Because this error points directly to the power supply wiring, the first diagnostic step is to disconnect the range from power, inspect the terminal block connections at the rear of the appliance, and verify that each wire is seated correctly and torqued to the appropriate terminal. The error message should clear immediately once the supply cable is properly installed and power is restored. If the error persists after correcting the connection, further evaluation of the home's circuit wiring or the range's terminal block may be needed.

Common causes of Line Error

  1. 01

    Incorrectly wired terminal block

    Wiring / connection

    The power supply cable wires are connected to the wrong terminals at the back of the range. This is the most frequent cause and is often the result of a recent installation or appliance move.

  2. 02

    Loose terminal connection

    Wiring / connection

    One or more wires at the terminal block are not fully seated or have loosened over time, creating an intermittent or incomplete circuit that the range detects as a line fault.

  3. 03

    Wrong wiring configuration (3-wire vs. 4-wire)

    Wiring / connection

    The range may have been connected using a 3-wire cord without properly adjusting the neutral bonding strap, or vice versa with a 4-wire cord, causing a configuration mismatch the range flags as an error.

  4. 04

    Faulty or damaged power supply cord

    Part replacement

    The power cord itself may have a broken conductor, damaged insulation, or a defective plug end that is preventing a complete and correct supply connection.

  5. 05

    Improper household circuit wiring

    Wiring / connection

    The wall outlet or junction box may be incorrectly wired, with a missing neutral, reversed polarity, or an open leg on the 240-volt circuit, which would cause the range to detect a line error even if the cord is properly connected.

Frequently asked questions about Line Error

What does Line Error mean on a Samsung range?
Line Error on a Samsung range means the appliance has detected that the power supply cable is incorrectly installed or the electrical connection is improperly wired. The range checks its incoming power during startup and displays this message when it finds a problem with the supply connection. It is not an internal component failure but rather a signal that the power wiring needs to be inspected and corrected.
How do I fix a Line Error on my Samsung range?
Start by disconnecting the range from power and inspecting the terminal block connections at the rear of the appliance. Confirm that each wire from the power supply cord is connected to the correct terminal and that all connections are tight and secure. Also verify that the wiring configuration matches the cord type being used, either 3-wire or 4-wire. Once the connection is corrected and power is restored, the Line Error message should disappear.
Is a Line Error on a Samsung range a safety hazard?
Yes, an incorrectly wired power connection can pose a serious electrical safety risk, including the potential for shock, overheating, or fire. You should not attempt to use the range while this error is displayed. If you are not comfortable working with 240-volt wiring, contact a licensed electrician or appliance technician to inspect and correct the connection before operating the appliance.
Will resetting my Samsung range clear the Line Error?
Simply resetting the range by cycling power will not clear the Line Error if the underlying wiring problem has not been corrected. The error is generated because the range detects an issue with the incoming power supply, and it will continue to display the message each time power is applied until the connection is properly installed. The error should clear on its own once the wiring is fixed and the range is powered back on.
How much does it cost to fix a Line Error on a Samsung range?
If the issue is simply a loose or incorrectly connected wire at the terminal block, the repair may cost nothing if you handle it yourself, or roughly $75 to $150 if you hire a technician for a service call. If a new power supply cord is needed, parts typically range from $20 to $60 depending on the cord type. If the home's circuit wiring is found to be at fault, an electrician's repair could range from $100 to $300 or more depending on the scope of work.
