why are the flames yellow on my Fisher & Paykel CG604C or CG905C cooktop?
on CG604C or CG905C cooktops, yellow flames can involve wet or blocked burner ports, but incorrect gas type or pressure can also be responsible. turn off burners with persistent yellow flames and arrange a licensed gas check.
model scope: for CG604C and CG905C gas cooktops.
let the cooktop cool and record whether the change followed cleaning or installation. do not adjust jets, regulators or gas connections or repeatedly light burners to diagnose the supply.
the linked guide is for safe shutdown and arranging qualified assessment, not a gas-adjustment tutorial. if you smell gas, do not operate electrical switches. turn burners off, shut the gas supply only if safe, ventilate and seek urgent gas assistance, leaving the cooktop out of use.
first checks
- record the recent change
with burners off, note whether the symptom followed cleaning or installation and give that history to the licensed repairer.
possible causes
- wet or dirty burner ports
- incorrect gas type or supply pressure
