My problem is not consistant and works fine when cold and then all of a sudden it wont fire up again when hot and goes into lock out and wont reset until the next day.Works on & off by using the water temp dial so that must be ok.Changed jet,solenoid valve,control box,photocell and next port of call is the transformer as it has to be a spark issue as it stinks of fuel when it locks out.electodes look fine & no cracks & does anyone have the settings for them or any other ideas.Trianco tro mk3 15/19.Thanks.
