GE Range Error Code 100

Error code 100 means the range detected a miswire condition on its 240VAC electrical supply during the first 10 minutes after being powered on. The control board checks the incoming wiring at startup and locks out operation if it does not see the correct voltage configuration. This is a safety feature designed to protect the appliance and prevent a potentially hazardous situation from a wiring error.

No. A miswire condition on a 240VAC circuit is a serious electrical safety hazard. The range should not be used until the wiring has been inspected and corrected by a qualified technician or licensed electrician. Operating appliances on an incorrectly wired circuit can cause component damage, tripped breakers, or a fire risk.

If the problem is only a wiring correction at the terminal block, the repair can cost very little, mainly just the time for a service call in the range of $75 to $150 for a technician visit. If the issue is at the household circuit or outlet and requires an electrician, expect costs in the range of $100 to $300 depending on the scope of work. If a damaged power cord needs replacement, cords typically cost between $20 and $60 for the part.

Only if the wiring problem has already been corrected. Code 100 is a latched fault that clears on the next power-up, but only when the miswire condition is no longer present. If you cycle power without fixing the underlying wiring, the code will return as soon as the control completes its startup check within the first 10 minutes.

Start by turning off the circuit breaker and inspecting the wire connections at the range's terminal block, comparing them to the wiring diagram on the back of the appliance. Verify that both hot legs, the neutral, and the ground are landed on the correct terminals and that all connections are tight. If the terminal block wiring is correct, check the wall outlet and circuit breaker connections. Once the wiring is confirmed correct, restore power to see if the code clears.
