AEG Gas Hob For Gas Cooker Goes Out

[gavski]

One of the rings on my AEG gas hob has developed a problem -
It only stays alight when the knob is depressed (and the igniter clicks).
as soon as I let go of the knob the flame goes out.
I have cleaned the jet and when it is alight the gas flow looks good and the flame is a good color.

any advice,

cheers.

Hi
Sounds like the thermocouple needs to be replaced, that's the little rod shaped thing at the side of the burner.
For reasons of safety, I cannot advise DIY repairs on a gas appliances though.
