Gas Rangemaster sparking problem

[damurphster]

I have a 110 Gas rangemaster.

All bar one (RHS oven) of the spark lighters have suddenly stopped working.

Anything obvious I should be looking at?

Anyone got a 'take it apart' manual??

They are making the noise but not sparking at all.

I am struggling for access as I cannot pull the oven fully out due to the gas connector pipe not being long enough!!

Any help appreciated.

Edited to add: Both lights and the hotplate all work fine

Just found this:

If you look at page 29 - I don't really understand it all but it looks like there is a lot of earths on the RH oven and the LH oven is separate.

Could it be that the 'spark generator' is knackered on the LH oven and that is the one that works the hobs?
