What bAd LinE bAd means on a GE range
The bAd LinE bAd error on a GE range is a voltage monitor fault that indicates the control board has detected an incorrect or missing voltage condition at the power supply connections. Specifically, this code triggers under two conditions: 120VAC is not detected between the neutral terminal J2-15(N) and the L2 terminal J20-3, or the voltage measured between L1 at J20-1 and L2 at J20-3 is below 200VAC. These measurements are taken directly by the control board to confirm that a proper 240VAC split-phase supply is present and correctly wired to the unit.
The most common root cause is a miswired terminal block, which is the connection point where the range's power cord attaches to the appliance. If the hot legs (L1 and L2), neutral, or ground conductors are connected to incorrect terminals, the control board will not see the expected voltage relationships and will display this fault. This can occur after a cord replacement, a recent installation, or if the range was moved and reconnected incorrectly. Wiring errors at the wall outlet or a shared neutral fault in the home's electrical panel can also produce this condition.
Diagnosis should begin at the terminal block. Using a multimeter, verify that 120VAC is present between J2-15(N) and J20-3(L2), and that 240VAC or greater is present between J20-1(L1) and J20-3(L2). If voltages are absent or out of range, trace the issue back through the power cord connections and the supply circuit. A failed or open leg at the breaker panel, a damaged power cord, or a loose terminal connection can all produce the same fault signature.

Common causes of bAd LinE bAd
- 01
Miswired terminal block
Wiring / connectionThe most frequent cause is incorrect connection of the power cord to the terminal block, where L1, L2, or neutral conductors are placed on the wrong terminals. This often happens after a cord replacement or reinstallation.
- 02
Lost or open L2 leg from the breaker panel
Wiring / connectionIf one of the two 120VAC hot legs supplying the range is open or tripped at the breaker, voltage between L1 and L2 at the terminal block will drop well below 200VAC, triggering this fault. Check the double-pole breaker for the range and confirm both legs are energized.
- 03
Damaged or incorrect power cord
Part replacementA power cord with a broken conductor, or a 3-wire cord installed where a 4-wire cord is required, can create missing or incorrect voltage at one or more control board terminals. Inspect the cord for visible damage and confirm it is the correct type for the installation.
- 04
Loose or corroded terminal block connection
Wiring / connectionEven if wiring is correct, a loose screw or corroded contact at the terminal block can cause high resistance or an open circuit on a supply leg, resulting in low or absent voltage at the control board's sense points.
- 05
Faulty wall outlet or receptacle
Part replacementA damaged 240VAC receptacle can fail to deliver one or both hot legs at the proper voltage. Testing voltage at the outlet with a multimeter will confirm whether the problem is upstream of the range.
