What to check first
Stop normal operation while this warning is active. Follow only the documented safe checks or protective-drain instructions for the exact model.
Basic checks
- Stop using the range or oven.
- Turn power off only at a safe, accessible breaker.
- Do not inspect or correct range wiring yourself.
- Check for recent installation or outlet work from the service history; if yes, treat wiring as unresolved.
- Check whether the display shows the code immediately after power-up; if it does, keep the appliance off.
- Record when the code appears after power is restored; if it repeats, keep the range off until qualified service.

Can I keep using it?
Use extra caution when gas, high heat, or high-voltage components may be involved. Do not inspect gas lines or live wiring as a basic check.
Persistent headaches, dizziness, nausea, or weakness near a gas appliance can be a carbon monoxide warning: leave the area, ventilate only if safe, and call emergency services or qualified service for a CO check.
- Safe next step
- If you smell gas: do not operate switches or the appliance, leave the area, and call your gas utility's emergency line or emergency services from outside.
- Stop when
- You smell gas, see electrical warnings, the appliance smells hot, or a gas/electrical supply concern returns.
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
