Terminal block cord miswire detected; appears if 120VAC is not present between J2-15(N) and J20-3(L2), or if less than 200VAC is present between J20-1(L1) and J20-3(L2).

First step from the service manual

Check terminal block wiring and verify correct voltage at J2-15(N)/J20-3(L2) and J20-1(L1)/J20-3(L2).

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

  1. 01

    Incorrect terminal block wiring

    Wiring / connection

    The 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.

  2. 02

    Loose or poorly secured terminal block connection

    Wiring / connection

    A 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.

  3. 03

    Wrong power cord type installed

    Part replacement

    Installing 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.

  4. 04

    Damaged power cord or wire

    Part replacement

    A 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.

  5. 05

    Faulty control board connector

    Wiring / connection

    If 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.

Frequently asked questions about bAd LinE

What does bAd LinE mean on a GE range?
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.
Can I fix the bAd LinE error myself?
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.
Is it safe to use my GE range while it shows bAd LinE?
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.
Will resetting the range clear the bAd LinE error?
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.
How much does it cost to fix a bAd LinE error on a GE range?
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.
