Falcon Incorrect Combustion / Air–Gas Mixture Fault

Gas hob burner flame is yellow, noisy, or lifts off the burner instead of being blue and stable.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Blocked primary air inlets, Incorrect burner cap placement, Wrong gas type or incorrect injector fitted, Low or high gas pressure

Safety first: Turn off gas. Do not operate burners with abnormal flames.

Clean and reseat: Clean burner heads and caps, then ensure caps are correctly seated.
Check air inlets: Inspect the air shutters or inlets under the hob for dust or grease; clean as needed.
Verify gas type: Confirm the range is jetted for your gas type (natural gas vs LPG). If recently converted or installed, have a gas-safe technician verify injectors and pressure.

Persistent yellow or lifting flames require professional adjustment to avoid carbon monoxide risk.
