Possible Causes
How to Fix / Troubleshooting
Safety first: Turn burner OFF and allow it to cool before cleaning. Do not modify gas components with the gas supply on.
- Clean burner ports: Remove the burner cap and head. Use a soft brush or a wooden toothpick to clear debris from each port. Do not enlarge the holes.
- Check gas shutoff: Verify the gas shutoff valve to the range is fully open (handle parallel to the pipe).
- Confirm gas type: Ensure the range has been converted correctly for your gas type (natural gas or LP). Incorrect orifices can cause low or uneven flames.
- Compare burners: If all burners are weak, the regulator or supply pressure may be low and should be checked by a gas technician.
When to call a technician: If cleaning does not restore normal flame or if you suspect incorrect conversion or regulator issues, contact a qualified gas technician.
