Hi. I worked on a 2.5 year old JW40 last week with FVIR. The tco had opened and i decided to replace it with a new one. Before doing that, i thoroughly clean the the flame arrester grill from the top and bottem. Shook out and vacuumed the burner since it was out and vacuumed the inside combustion chamber and the outsides. A week later the tco opened again and after resetting it, it opend again before hitting the set temperature. Have i missed something in handling this service call? Your advice is appreciated. There is no piping brought in for combustion air but i felt that might not be it as this is the first tco problem they are having.
No announcement yet.
