GE Range Error Code bAd LinE bAd

The bAd LinE bAd code is a voltage monitor error indicating that the control board is not detecting the correct voltages at its power supply input terminals. It activates when 120VAC is absent between the neutral terminal J2-15(N) and L2 at J20-3, or when less than 200VAC is measured between L1 at J20-1 and L2 at J20-3. The most common cause is a miswired terminal block, but a wiring fault in the home's electrical supply can also trigger it.

Yes, this error indicates a potentially unsafe wiring condition and the range should not be operated until the fault is resolved. Incorrect wiring at the terminal block or a missing supply leg can pose a risk of electrical shock or equipment damage. If you are not comfortable working with 240VAC wiring, contact a licensed electrician or qualified appliance technician.

If the fix is simply correcting a miswired terminal block, the cost can be minimal since no parts are needed, though a service call from a technician typically runs in the range of $75 to $150 for diagnosis and labor. If a new power cord is required, parts generally cost between $20 and $60 depending on cord type. If the problem originates at the home's electrical panel or outlet, an electrician's repair costs can range from $100 to $300 or more depending on the scope of work.

Start by turning off the range's circuit breaker and inspecting the terminal block where the power cord connects to the appliance. Confirm that L1, L2, and neutral are connected to their correct terminals according to the wiring label on the range. Then restore power and use a multimeter to verify 120VAC between J2-15(N) and J20-3(L2) and at least 200VAC between J20-1(L1) and J20-3(L2). If voltage is missing or low, check the breaker panel and the power cord for faults.

Resetting the range by cycling the breaker will not permanently clear this error if the underlying wiring or voltage problem has not been corrected. The control board continuously monitors the supply voltages and will redisplay the fault as soon as it detects the out-of-range condition again. The error will only stay cleared once the correct voltages are present at all three sense points.
