GE Range Error Code SUPPLY OPEN NEUTRAL

SUPPLY OPEN NEUTRAL means the range's internal power monitor has detected that the voltage between the L1 hot leg and the neutral conductor has dropped below 90VAC. This indicates the neutral wire in your electrical supply is open, broken, or has a failed connection somewhere between the range and your electrical panel. It is a supply-side electrical fault, not an internal range component failure.

Resetting the range by cycling the breaker will not permanently clear this error if the underlying wiring fault remains. The power monitor will detect the low neutral voltage again when the range is powered back on and the error will return. The fault must be corrected at the source before the error will stay cleared.

The cost depends on where the fault is located. If the fix is simply retightening a loose wire at the terminal block or replacing a power cord, the cost is relatively low, typically in the range of $20 to $150 including parts and labor. If the problem is at the wall receptacle or within the branch circuit wiring, electrician labor costs will apply, generally ranging from $100 to $400 or more depending on the complexity of the repair and local rates.

No, you should not operate the range while this error is active. An open neutral condition can cause one leg of the 240VAC supply to carry overvoltage, which can damage the range's electronics and heating components. The condition also represents a wiring fault that poses a potential fire or shock hazard and should be corrected before resuming use.

Start by turning off the breaker and inspecting the neutral wire connection at the terminal block on the back of the range, looking for looseness, corrosion, or burn marks. If that connection is secure, check the wall receptacle or power cord connections next. If the fault is not found at the range or receptacle, the issue is likely at the panel or in the branch circuit wiring and will require a licensed electrician to diagnose and repair.
