Possible Causes

Partially clogged burner ports, Incorrectly converted orifice for LP/natural gas, Low gas pressure, Misadjusted burner valve

How to Fix / Troubleshooting

Safety first: Turn off burners and allow them to cool before cleaning. Do not modify gas orifices without proper knowledge.

  • Clean ports: Remove the burner cap and head. Use a soft brush or a straightened paper clip to gently clear each port. Do not enlarge the holes.
  • Check cap position: Ensure the cap is correctly seated and not rocking.
  • Verify gas type: Confirm your Summit range has been converted correctly for your gas type (natural or LP). The orifices and regulator must match. If unsure, have a qualified technician verify the conversion kit installation.
  • Pressure check: If all burners are weak, contact your gas supplier or a technician to measure and adjust gas pressure.
