How to Fix / Troubleshooting
Safety: If you smell gas, shut off the main gas supply, evacuate, and call the gas company.
Steps to check:
- Manual gas valve: Confirm the gas cock near the Heil furnace is parallel to the pipe (open).
- Other gas appliances: Check if stove or water heater work to verify gas supply to the home.
- Gas valve wiring: With power off, ensure the gas valve connector is firmly attached and wires are intact.
When to call a pro: If the ignitor glows but there is no gas flow, a technician must test gas pressure, valve voltage, and replace the gas valve if defective.
