GE Range Error Code bAd LinE

The bAd LinE code means the range's control board has detected incorrect or missing voltage at the terminal block where the power cord connects. The board checks for 120VAC between the neutral pin (J2-15) and L2 (J20-3), and for at least 200VAC between L1 (J20-1) and L2 (J20-3). If either reading falls outside the expected range, this fault is triggered. It is essentially a miswire or power supply fault, not an internal component failure.

No, you should not attempt to operate the range while this error is active. The code indicates a potentially dangerous wiring condition where voltage may be misrouted or a connection may be absent. Using the range in this state poses a risk of electrical shock, tripped breakers, or damage to the control board. Disconnect power until the wiring is inspected and corrected.

If only a wiring correction at the terminal block is needed, the repair may cost nothing beyond your time, or a modest service call fee ranging from roughly $75 to $150 if a technician performs the work. If a replacement power cord is required, cord pricing typically falls in the $20 to $60 range depending on the cord type. Control board replacement, if a damaged board connector is to blame, can range from $150 to $400 or more for parts and labor.

In many cases, yes, if you are comfortable working with high-voltage wiring. The fix typically involves opening the terminal block cover, verifying that each wire is connected to the correct terminal, and confirming all screws are tight. Always disconnect power at the breaker before inspecting the terminal block. If the wiring looks correct, verifying actual voltage at the board connectors requires a multimeter and additional expertise.

Resetting the range by cycling the breaker will not permanently clear this error if the underlying wiring problem has not been corrected. The control board checks line voltage at startup, so the fault will return as soon as power is restored and the board detects the same incorrect voltage readings. The wiring issue at the terminal block must be resolved first.
