What bAd LinE means on a GE range
The bAd LinE error code on a GE range indicates that the control board has detected a miswire condition at the terminal block, the connection point where the range's power cord connects to the appliance. Specifically, the error triggers under two conditions: when 120VAC is not present between connector pin J2-15 (neutral) and J20-3 (L2), or when less than 200VAC is measured between J20-1 (L1) and J20-3 (L2). These measurements represent the range's ability to verify correct split-phase 240VAC service, where each leg should contribute approximately 120VAC relative to neutral and roughly 240VAC leg-to-leg.
This code most commonly appears after a power cord replacement, a recent installation, or when a range is moved and reconnected. On a properly wired 4-wire installation, L1, L2, neutral, and ground each occupy a dedicated terminal position. If the cord is connected with L1 and L2 reversed relative to the board's expectations, or if a wire is loose or absent at the terminal block, the voltage readings at J2-15 and J20-3 will fall outside the acceptable range and trigger the fault. A 3-wire cord installation on a range expecting 4-wire service can also produce this condition.
Diagnosis requires verifying actual voltage at the specified connector pins on the control board, not just at the wall outlet. Even if the outlet tests correctly, a loose terminal block screw, a damaged wire lug, or an incorrectly pinned connector on the board side can prevent proper voltage from reaching the measurement points. A digital multimeter set to AC voltage is essential for tracing the fault to its exact location.

Common causes of bAd LinE
- 01
Incorrect terminal block wiring
Wiring / connectionThe power cord wires are connected to the wrong terminals on the terminal block, causing the control board to read incorrect voltages at J2-15, J20-1, or J20-3. This is the most frequent cause after a cord replacement or new installation.
- 02
Loose or poorly secured terminal block connection
Wiring / connectionA wire lug that is not fully tightened at the terminal block can result in intermittent or absent voltage at one of the measured pins. Inspect each terminal screw for proper torque and full wire contact.
- 03
Wrong power cord type installed
Part replacementInstalling a 3-wire power cord on a range configured for 4-wire service, or vice versa, can result in missing neutral or L2 voltage at the board connectors, triggering this fault.
- 04
Damaged power cord or wire
Part replacementA cut, burned, or broken conductor in the power cord itself can interrupt voltage on one leg before it reaches the terminal block. Visually inspect the cord along its full length and check for heat damage near the terminal connections.
- 05
Faulty control board connector
Wiring / connectionIf the internal wiring harness connector at J2-15, J20-1, or J20-3 is damaged, corroded, or not fully seated, the board cannot read correct voltages even when the terminal block is properly wired. Confirm connector seating and inspect pins for damage.
