I got a real chin scratcher of a problem on this broiler I work on. I have to replace the lower burner sensor every 30-45 days. It is a the same location and I can't find anything wrong with the flame sensor, or the ignition module. As a matter a fact the last flame sensor I removed I installed at another location just to see if it would work and of course it did. When I check my mA they are all over the place unless I remove the sensor and place it in the flame by hand but as soon as I reinstall it, it won't work. I can't see any cracks in the insulation but who knows. Duke is going to have me send back one of the old flame sensors so they can test it and look it over but I don't think there is anything wrong with it. Any ideas?
