GE Range Error Code bAd

The bAd error code on a GE range indicates that the appliance has detected a miswired electrical connection between the household supply and the unit itself. The display alternates between 'bAd' and 'linE' accompanied by a loud audible tone to alert users to this condition. This is a line-voltage detection fault, meaning the range's internal circuitry has identified an abnormal or incorrect configuration in the incoming power supply before normal operation can begin.

Electric ranges require a specific wiring configuration, typically a 240V circuit using a 3-wire or 4-wire setup depending on local code requirements and installation era. Common miswiring scenarios include swapped neutral and ground conductors, incorrect polarity on the hot legs, or missing connections at the terminal block. The range continuously monitors the incoming line voltage configuration and will trigger this fault if the detected wiring does not match the expected parameters.

Because this fault originates at the household wiring level rather than within the appliance itself, the range is functioning correctly by refusing to operate. Attempting to bypass or reset the error without correcting the wiring is unsafe and will not resolve the fault. The appropriate corrective action is to have the original installer or a licensed electrician inspect and correct the wiring at the range terminal block or the household circuit, including the outlet, junction box, and breaker connections.
