How to Fix / Troubleshooting
Safety warning: If you smell gas, do not attempt to light the furnace. Evacuate the area and call your gas utility.
- Check gas shutoff: Verify that the gas cock near the furnace is parallel to the pipe (ON position). Ensure any upstream shutoffs are also open.
- Confirm other gas appliances: Test a gas stove or water heater to see if they operate normally, indicating that a gas supply is available.
- Observe gas valve operation: During ignition, listen for a click from the Bryant gas valve when the ignitor is hot. No click may indicate a failed valve or control.
- Inspect burner orifices: With the gas supply off and burners removed, check the orifices for debris or spider webs. Clean gently with compressed air; do not enlarge the holes.
If the gas valve is receiving proper voltage but does not open, it must be replaced by a qualified technician.
