Thetford Fridge not Lighting on Gas?

[TerryIvybridge]

Supposed to go off grid tomorrow but fridge won't light on gas? Burner box cover off and I can't see any ignition spark with gas on and gas selectected on gas? Any ideas where to look please?

Hi! Just to say this issue is now resolved. A dodgy solennoid being the cause.
