Gas cooker ignitions

[psd99]

Hi, Two of the five gas hob burners on my Samsung cooker are not sparking, so I have to use a match to light them.

I have tried cleaning the white ignition electrodes. I managed to get both working briefly, but they then stopped again.

There are two screws on each burner, and I removed them, but the glass hob surface made it difficult to lift the burner assembly out. Is this something I can safely repair myself, or is it time to call a Gas Safe professional?

Also, on some of the burners that do light, the flame ring is not completely even all the way around some sections do not produce a full flame. It has apparently been like this for a while.

Actually the reason behind all of this is to get the gas safety pass for a rental
I did wonder if anyone knows would it completely fail the gas test like this? Suppose it neede to be repaired by a gas safe enginner
I thought id ask on here because i have got some great advice over the years

Thanks

you've lifted off the the iron burner caps where the gas ignites and cleaned /checked for corrosion/scale brush/brass wire brush,
fibre glass pen useful on electrodes, can pull bits of thick thread through burner holes too.

Yes lifted off
There is debris inside ie its kind of under the glass i havent removed that

But let me take a look at the fibre glass pens good suggestion

There is defo debris buildup on the white ignition but i cant seem to clean it properly i tried a wire brush i need something very fine to get in there
Fibre glass pen might do it
