Possible Causes

Partially blocked burner ports, Incorrect injector (jet) size for gas type, Low gas pressure, Misaligned burner cap

How to Fix / Troubleshooting

Safety first: Turn off the burner and allow parts to cool before handling.

Steps:

  • Clean burner thoroughly: Remove burner cap and head. Soak in warm soapy water, then clean each port with a soft brush. Rinse and dry completely.
  • Re-seat burner cap: Ensure the cap is correctly positioned and stable. A misaligned cap causes yellow or noisy flames.
  • Check gas type: Verify that the appliance is configured for your gas type (natural gas vs LPG). If converted, ensure the correct Brandt injector set is installed.
  • Call gas technician: If flames remain yellow or very weak, a licensed gas technician should check gas pressure and injector sizing.
