How to Fix / Troubleshooting
Safety first: If you smell gas, stop immediately and ventilate the area. Do not attempt repeated lighting.
Step-by-step checks (older pilot models only):
- Follow lighting instructions: Use the exact procedure in the user manual for lighting the pilot.
- Hold button long enough: Keep the pilot button depressed for the recommended time to heat the thermocouple.
- Check for drafts: Ensure no strong drafts are blowing directly onto the pilot area.
When to call a professional: Thermocouple replacement and pilot cleaning should be done by a gas-safe technician.
