what to do about yellow flames on a Fisher & Paykel gas cooktop
on CG604C and CG905C, persistent yellow flames need the burner condition and gas supply checked. turn the burners off, let the cooktop cool and arrange a licensed gas check.
tell the repairer whether the change followed cleaning or installation. wet or blocked ports and an incorrect gas type or pressure are possibilities, not a confirmed diagnosis.
