This cooktop has five burners. When I turn on the front right burner, it lights properly but the igniters keep sparking on the other four burners. After turning on a second burner, the igniters keep sparking.
If I do not turn on the front right burner, the other four work properly, i.e. after turning on any other burner, the igniters stop sparking.
In summary, the problem seems to be restricted to the front right burner - when it’s on the igniters spark. When it’s off, the other four burners and igniters work properly.
Any ideas/suggestions?
