I have a New World Series 2 Hob. All the burners ignite separately and the gas flame looks normal. However, last week when I tried to turn on more than one burner, the previously lit burner kept going out. This week I seem to be able to light 3 burners simultaneously but when I try to light the forth burner, the gas supply cuts out to all of them!
Do you know what causes this and is it something I can repair myself?
