Only the obvious, check wiring, if switch pull the switch out and see what's wrong with it. Not really that much help I'm afraid.

Ahh, Jacent - isn't the oven brand, "Smeg", not Smev?

The basic problem is usually dirty igniters. Give the igniter a good clean to remove the cooked-on material that is making it spark continually.

Here's a video of an American fixing his stovetop igniter. Not the same brand, but possibly the identical cause for your problem.

Cheers, Ron.

Hi Ron thanks for the reply, it is actually a smev not smeg brand apparently made for RV and marine. So the issue is only the one inside the oven that lights the griller. I’ll have a look at the video, although this oven doesn’t look like it’s ever been used so I doubt it’s dirty but you never know?

On our mains-ignition gas wall ovens, the igniter continues to spark until the FLAME MONITOR indicates there is actual ignition. The flame monitor on the older one was a wire probe into the flame zone, and a couple of times required tweaking its position to achieve correct sensing. (Haven't been allowed to pull the new one apart yet, it isn't even a week old!).

May not be related to your issue, but worth a look?

The issue is that without even wanting to use the oven at all, the minute I plug the van into power the oven igniter starts sparking on its own and won’t stop regardless of the knob position. So I have to leave the power off until I figure it out.

Jacent - Here's some more discussions around constantly-clicking stove or oven ignitors.

Fixya - Gas hob - constant ignition problem

It seems like the two main sources of problems are a sticky ignitor switch, which actually stays on after it's released - or excessive moisture in the ignitor itself.

I'm hazarding a guess, an oven ignitor has much less chance of getting moisture in it, as a stove hob ignitor would - so maybe the answer is in the sticky switch mechanism.

I'm a little puzzled as to why the ignitor cranks up as soon as the power is switched on.

Most ignitors I've seen are piezo-electric (just pressing the button gives a piece of special crystal a whack, which produces the spark) - and they don't require electric power to operate.

Do you have a Smev manual anywhere, that might have come with the 'van? - or can you find one online (usually located on the manufacturers website) - which might shed some light on ignitor troubleshooting.

Cheers, Ron.
