How to Fix / Troubleshooting
Safety first: If you smell gas, do not operate any electrical switches. Ventilate the area and close the gas supply valve immediately. Contact gas supplier if leak is suspected.
- Check gas valve: Ensure the main gas shutoff valve to the cooktop is fully open.
- Verify gas supply: Confirm other gas appliances in the home are working.
- Reset lockout: Disconnect power for 5 minutes, then restore and test. Some models clear F4 after a power reset if the cause is removed.
When to call a technician: Persistent F4 indicates a fault in the internal gas valve or safety system and must be serviced by a qualified gas technician.
