how can i fix my rangemaster 110 gas cooker?

I have just experienced the same on mine. I cleaned out all the burner holes and have a nice blue flame. Physically blowing out the oven ignition flame instantly forces the sparker to relight so I'm thinking FFD is fully functional here?
What I have noticed, is the sparker (one with the ceramic coat) glows red hot after a few seconds in the flame. That doesn’t happen in the other oven (which works).
I reckon swapping the unit over would prove it but that's a bit too much like hard work for me right now. Can anyone else comment before I get the tool kit out?

On gas cookers the burner may become blocked with grease or other debris. This will restrict the gas flow and give the symptoms that you are having. If you get some stainless steel scourer (not brillo) and rub this up and down the burner this may solve the problem.

The ffd sounds faulty
