# Asko gas hob burner and igniter repair

### No codes at all, which makes it the simpler call

Gas hobs on this make publish nothing, so the diagnosis is flame, spark and gas train, done by observation and measurement. Clicking without lighting, lighting and dropping out, and burning yellow are three different problems — igniter, flame supervision and burner geometry — and which it is can usually be told before anybody arrives. Every burner is checked whatever the complaint was, because supervision is a safety system and half a check is not one. Anything beyond the appliance is named for you rather than worked around.

What this involves

No codes on gas here — flame, spark and gas train, measured

Clicking, dropping out and burning yellow are three separate problems

Left safe rather than merely working, and we say when it is not our trade

Watch each burner light and hold

Spark, flame shape, and whether the flame survives the flame-supervision delay. That sequence separates igniter from thermocouple immediately.

Clean and check the burner parts

Caps, crowns and ports cleared and seated correctly — a cap a few degrees out produces a yellow flame and a call-out.

Test supervision and leave it safe

Flame supervision proved on every burner and the gas connection checked. Anything beyond the appliance is named for you rather than worked around.

### It lights and then goes out when I let go.

Flame supervision: the thermocouple or its sensor is not confirming the flame within the delay. It is an ordinary part and it is the most common gas complaint we take.

### One burner burns yellow.

Usually the cap or crown sitting a few degrees out of position after cleaning, which costs nothing to correct. Where it is not, the port pattern or the gas train is the next question and it is measured rather than adjusted by eye.
