How to Fix / Troubleshooting
Safety first: Turn off gas and power. Repeated failed ignition can cause gas buildup.
- Bleed gas line (by professional): If the heater is newly installed or gas supply was interrupted, a professional may need to purge air from the gas line.
- Inspect igniter: Check for cracks or discoloration and replace if suspect.
- Gas supply check: Ensure the gas shutoff valve is fully open and that the gas meter or tank has adequate supply.
- Professional testing: A technician should measure manifold and inlet gas pressures and verify gas valve operation.
