we have been having on & off problems with our small gas burner on our hob.It used to stay lit but now doesn't even to that.We have replaced the thermocouple but no joy.Stoves won't give us any more info to what the problem is unless we pay £140 for an engineer plus parts.Sorry but we haven't got that sort of money at the moement.Has anyone had the same problem or any ideas to our problem?
