Step-by-Step DIY Fix Guide
- SAFETY: Turn off the range breaker immediately. Do not attempt to use the range.
- Do not attempt to diagnose or repair the wiring yourself unless you are a licensed electrician.
- Check the circuit breaker panel — if the double-pole breaker for the range has one side tripped, reset it. If it trips again immediately, a wiring fault exists.
- Contact a licensed electrician to inspect the range terminal block wiring and the wall circuit.
- GE Appliances Service (1-800-432-2737) can verify the range terminal block connection is correct if the household wiring is confirmed good.
If the door warning comes back
- If the door closes normally but the warning keeps returning, the latch or switch path becomes more likely than a simple alignment issue.
- Immediately — BAD LINE means the range is receiving incorrect power and must not be used
What This Error Means
Error BAD LINE on your GE Appliances oven means: The range has detected incorrect wiring at the power supply connection — typically a missing or reversed neutral leg on a 240V circuit. Operating the range with bad line wiring can damage the electronics and creates a shock hazard. Also displayed as Bad Line on some GE models. The oven's self-diagnostic system has detected this condition and stopped operation.
The most frequent cause is neutral wire not connected at the junction box or range terminal block. Work through the causes and fix steps below in order.
GE's official guidance classifies BAD LINE as a technician-only fault. A 60-second power reset is the only DIY step — if the code returns, contact GE Appliances Service at 1-800-432-2737.
BAD LINE means the range is receiving incorrect power — this is an electrical safety issue, not an appliance fault. A licensed electrician must inspect the circuit before the range can be safely used. Do not attempt to diagnose 240V wiring without proper training and tools.
Most Likely Cause by Symptom
The GE Appliances oven may stop, pause, or refuse to complete the cycle normally.
Likely cause: Neutral wire not connected at the junction box or range terminal block
Check first: SAFETY: Turn off the range breaker immediately. Do not attempt to use the range.
The warning may return immediately because the appliance is detecting an internal fault.
Likely cause: L1 and L2 legs of the 240V supply swapped or one leg missing
Check first: Do not attempt to diagnose or repair the wiring yourself unless you are a licensed electrician.
Common Causes
- Neutral wire not connected at the junction box or range terminal block
- L1 and L2 legs of the 240V supply swapped or one leg missing
- Range power cord wired incorrectly — especially common when a 3-wire cord was replaced with a 4-wire cord without updating the grounding connection
- Faulty wall receptacle with wiring fault
- Tripped breaker on one leg of the 240V circuit — range gets only 120V on one leg
What Not to Do
- Do not reset the breaker and resume using the range without a wiring inspection — repeated operation on incorrect wiring will destroy the control board and heating elements
- Do not attempt to rewire the range terminal block yourself unless you are a licensed electrician
