I have a Bosch 60 cm gas cooktop from Harvey Norman. It is several years old. All the igniters have suddenly stopped working. I imagine there is a control module of some kind for these but I can only find information on replacing individual igniters, which is not the issue here.

I am keenly aware of the hazards of gas and electricity but I would like to know more about the design of this cooker and eventual replacement of the igniter module before deciding whether it is worth doing anything. I can’t seem to find a model number anywhere on the cooktop but it looks pretty similar to comparable ones currently on the HN website. Does anyone know more about these?

How many is ‘several’ years old? Is it a possible CGA situation?

Sometimes I just sit and think. Other times I just sit.

These usually plug into a standard 10A 3-pin plug under the bench (probably behind the oven, if you have the standard hob-over-oven setup). Check that it's still plugged in, switched on, and has power at the socket. Also check that, if there's a switch marked 'hob' above the benchtop, that's still switched on. Kids playing with switches causes a lot of nuisance faults.

Gas remains a hazard, but there should IIRC be an isolating valve under the hob that you can easily switch off. The electrical hazard can be easily removed by simply unplugging it.

It sounds like the part in question is probably called a 'spark module'. https://www.searspartsdirect.com/diy/repair-guide/how-to-replace-a-spark-module-on-a-gas-cooktop

Thanks for the replies. I can't remember when the cooktop arrived, but I'm sure it is well past CGA. It does have a standard plug and I have checked all of that. Unfortunately it is not a failure of power.

I made the hazard statement to avoid all the posts yelling at me to get a qualified service person. I know what not to do with gas and electricity. I am just trying to see if I can garner any technical information on the cooker before deciding how to proceed.

The gas connection is to a 9 kg bottle outdoors. However, the hose that connects to the cooker is rigid and the cooker cannot be moved or even raised to see underneath without disconnecting the hose. That means I would also have to reconnect it and I'm not prepared to do that at this stage.

Thanks for the link. This is exactly the kind of information I am looking for. Unfortunately it doesn't seem to apply to the Bosch unit I have, but I will investigate further.

It's likely that the actual component to replace will be similar. Disassembly to replace it appears to be the hard part.

We had a gas hob that started having issues with the igniter years ago. Had the tech come out and he got it going again.

But he mentioned that the heat from the cook top, starts causing the components for the igniter to start breaking down and that they get uneconomic to repair.

Sure enough, another year or 18 months later it stopped working.

We then used this sort of thing (~$6) for many years after - It wasnt really an issue.

And you always want one of these for any possible electricity outages anyway:

I guess it depends on how important the self igniter is to you and what you are prepared to spend on it.

Do not attempt to fix this yourself. These are not user repairable appliances. Get a suitably certified gas appliance service person in to do the repair.

I am not stupid about this kind of thing. I was looking for information to better understand the issue and what was involved in fixing it. Because of where I live, any repair job is likely to cost hundreds more just to have a suitably certified gas appliance service person come out here. Thanks to the above responses I have found what I wanted and know the parts I need and how to do the repair. It is something I probably could safely do myself but it is more trouble than I feel like going to. Using a barbie lighter is an acceptable workaround.

@Rikkitic my post was not about being rude it was about caring. I won't do that again.

I wasn't accusing you of rudeness, but I really do know what I am doing with this sort of thing. The electrical part is well within my abilities and the gas part is just a matter of disconnecting and reconnecting a hose. If I did that I would do it with thread seal tape and carefully check with soapy water afterwards that there was no leak. But in my old age taking the cooker apart is all too much hassle when it is not hard just to use a gas lighter. I just wanted to know what was involved and that question has been answered.

Having any certified repair person come out to my place is expensive and difficult so that is also part of the equation. I apologise if I offended you but I just wanted information and that has now been answered.
