What 100 means on a GE range

Error code 100 on a GE electric range indicates that the control board has detected a miswire condition on the 240VAC supply circuit during the initial power-up sequence. The control monitors incoming line voltage during the first 10 minutes after power is applied and compares the two legs of the 240V supply to verify correct wiring. If the wiring does not match the expected configuration, the control immediately flags this fault and locks out oven operation to prevent damage to components and potential safety hazards.

This is a latched fault, meaning the control board holds the error in memory and will not clear it simply by cycling power if the underlying wiring problem still exists. The only way to clear code 100 is to correct the miswire condition first, then restore power. If the supply wiring is now correct when power is reapplied, the control will not re-detect the fault and the error will be gone. If the miswire persists, the code will return immediately on each power-up cycle.

The most common sources of this fault are incorrect terminal connections at the range's terminal block, reversed or missing neutral and ground conductors, or incorrect wiring at the household circuit breaker or junction point. Ranges installed after a recent kitchen remodel, appliance swap, or DIY electrical work are particularly susceptible. On 4-wire installations, confusion between the neutral and ground wires at the terminal block is a frequent trigger for this code.

Common causes of 100

  1. 01

    Incorrect terminal block wiring

    Wiring / connection

    The most frequent cause is improper connection of the hot, neutral, and ground wires at the range's terminal block, especially during installation or after switching from a 3-wire to a 4-wire cord. Inspect each wire position against the wiring diagram on the back of the range.

  2. 02

    Reversed or swapped line voltage legs

    Wiring / connection

    If the two 120V hot legs at the terminal block are swapped or one is landed on the neutral terminal, the control will detect an imbalance and flag the miswire. Verify both hot legs are connected to the correct L1 and L2 terminals.

  3. 03

    Missing or improperly connected neutral wire

    Wiring / connection

    A floating or disconnected neutral causes the 240VAC circuit to read incorrectly to the control board. Check that the neutral conductor is firmly landed and not confused with the ground wire on 4-wire installations.

  4. 04

    Incorrect wiring at the wall outlet or junction box

    Wiring / connection

    Problems upstream at the household receptacle or service panel connection can produce a miswire condition even if the range cord itself is correctly attached. A licensed electrician should verify breaker and outlet wiring if the terminal block checks out.

  5. 05

    Damaged or incorrect power cord

    Part replacement

    A power cord with internal wire damage, incorrect gauge, or a 3-wire cord installed without properly reconfiguring the neutral-ground bonding strap on the terminal block can trigger this fault. Inspect the cord and verify the bonding strap configuration matches the cord type in use.

Frequently asked questions about 100

What does 100 mean on a GE range?
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.
Will unplugging and replugging my GE range clear error code 100?
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.
Is it safe to use my GE range while error code 100 is showing?
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.
How do I fix error code 100 on a GE range?
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.
How much does it cost to fix a GE range error code 100?
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.
