How to Fix / Troubleshooting
Safety first: Turn off gas and power before testing components.
- Observe igniter: If it glows but the burner does not light within 60–90 seconds, the igniter may be too weak.
- Test igniter current (advanced): Using a clamp meter, measure igniter current draw. If below manufacturer spec, replace the igniter.
- Check wiring: Inspect igniter wires for damage or loose connections.
- Gas valve: If a new igniter does not resolve the issue, the gas safety valve may be defective and should be replaced by a qualified technician.
