Noisy Gas Cooktop

I have a 7-year old Teknika gas cooktop powered by LPG.

Lately 2 of the burners have starting making a loud noise after being on for a few minutes.
The simmer burner however turns itself off when the noise starts. The noise is so loud the TV can't be heard.
Sorry don't know how to explain the noise.


Is this a major problem which would require a new cooktop or simply parts need to be replaced ?

If its popping then it needs anew regulator. The regulators that come with appliances are usually pretty terrible.

popping - do you mean the sound?
no it's not a popping sound but a constant whoosh or like a huge escape of gas/air, not even a whoosh
sorry just don't know how to describe it......the noise is constant, no stopping/popping, just constant flow of very loud noise

[url=<iframe]<iframe[/url]so i've worked out how to upload a video.......this is the sound my simmer burner is making - it's quite loud - then the gas goes out after about 3 minutes....so this will need a new regulator ?? if so, could someone give me a ballpark figure of cost as I don't want to spend a lot on a cooktop that's rubbish. If it's going to be an expensive exercise then I might be better off putting the money toward a new cooktop ????[url=<iframe]<iframe[/url]
