How to Fix / Troubleshooting
Safety First: Turn off power and gas before disconnecting any gas piping. Gas work should be done by licensed professionals.
- Verify gas valve position: Ensure the external gas shutoff handle is parallel to the pipe (open).
- Check other gas appliances: If they also do not work, contact your gas utility.
- Inspect gas valve wiring: With power off, check that the gas valve connector is firmly seated on the valve terminals and wires are not damaged.
- Professional testing: A technician should measure voltage at the gas valve during ignition and check gas pressure. If voltage is present but no gas flows, the valve likely needs replacement.
